Answer 1

Answer:

C (-5,[tex]\frac{8}{3}[/tex])

Step-by-step explanation:

I uses demos graphing calculator

First, found the slope using point (0,6) and (3,8)

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m = [tex]\frac{8-6}{3-0}[/tex]

m = [tex]\frac{2}{3}[/tex]

m = slope

Now I will be able to form a linear equation:

y = mx + b (is our y-intercept, when x is 0) When x is 0, y is 6 (0,6)

y = [tex]\frac{2}{3}[/tex]x + 6

I graphed that on demos, and that's how I got my final answer.

I would attach the link to the graph, but brainly deleted my answer before. So, try to write that in to demos (y = [tex]\frac{2}{3}[/tex]x + 6) if you want to see the graph.  

Hope that helps!

Leticia spends $18. 45 on a shirt. She spends at least $3. 00 more than Humberto spends. If h represents the amount Humberto spends, which symbol can be used to complete the inequality below to represent this situation? 18. 45 blank 3 h > < Greater-than-or-equal-to Less-than-or-equal-to.

Answers

Inequality is the comparison of mathematical expressions which are not strictly equal. The needed inequality is: 18.45 ≥ 3 + h

How to form mathematical expression from the given description?

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For the given case, we've got:

Amount spent by Leticia = $18.45

Amount spent by Humberto = h dollars

Since amount spent by Leticia is at least $3. 00 more than what  Humberto spends, thus:

18.45 is at least h + 3 (all in dollars)

(we usually skip stuffs like currency sign or units in equations or inequalities, to keep things as minimized as possible. It is known from the context what unit or currency or such thing is being discussed).

At least can be thought of as equal to that quantity or greater than that quantity but not less than that quantity.

This more than or equal to is written as ≥

Thus, the inequality we get is:

18.45 ≥ 3 + h

someone please give a step by step way on how to solve this problem

Answers

Answer:

10

Step-by-step explanation:

There are several ways to solve this problem which I’ll demonstrate these ways and see which method is way easier to understand.

First Method

This method is to convert the fractional expression to a single exponent expression using a law of exponent.

[tex]\displaystyle \large{\frac{m^a}{m^b} = m^{a-b}}[/tex]

In words, it means if both divisor (denominator) and dividend (numerator) have same values or are same, we can subtract the exponent from dividend (numerator) with divisor (denominator).

The dividend (numerator) exponent is unknown, let’s say it’s got ‘x’ as an exponent and this ‘x’ is what we are going to find since we don’t know its value.

Now we have the equation:

[tex]\displaystyle \large{\frac{m^x}{m^7} = m^3}[/tex]

Apply the exponent rules above.

[tex]\displaystyle \large{m^{x-7} = m^3}[/tex]

Solve an exponential equation - If both sides of equation have same base, we can solve the exponents.

Since LHS (Left-Handed Side) and RHS (Right-Handed Side) both have same base which is ‘m’ therefore, solve exponents.

[tex]\displaystyle \large{x-7=3}\\\displaystyle \large{x=7+3}\\\displaystyle \large{x=10}[/tex]

Therefore, the missing exponent is 10.

Additional Info

You can also use logarithm to solve an exponential equation.

[tex]\displaystyle \large{m^{x-7} = m^3}[/tex]

Take a logarithm of base ‘m’ both sides so we can apply other properties.

[tex]\displaystyle \large{\log_m m^{x-7} = \log_m m^3}[/tex]

From the property [tex]\displaystyle \large{\log_a b^n = n \log_a b}[/tex]

[tex]\displaystyle \large{(x-7) \log_m m = 3 \log_m m}[/tex]

From the property [tex]\displaystyle \large{\log_a a = 1}[/tex]

[tex]\displaystyle \large{(x-7)1 = 3 \cdot 1}\\\displaystyle \large{x-7=3}\\\displaystyle \large{x=10}[/tex]

______________________________

Second Method

This method is to isolate the term with missing exponent.

[tex]\displaystyle \large{\frac{m^x}{m^7} = m^3}[/tex]

Transport m^7 to multiply with m^3 via transportation property.

[tex]\displaystyle \large{m^x = m^3 \cdot m^7}[/tex]

We also have to apply another law of exponent as well.

[tex]\displaystyle \large{m^a \cdot m^b = m^{a+b}}[/tex]

Similar to the one with division (fraction), this one, when same bases multiply each other, we have to add both exponents while the other one subtracts exponents.

[tex]\displaystyle \large{m^x = m^{3+7}}\\\displaystyle \large{m^x = m^{10}}[/tex]

In the first method, we know that when solving an exponential equation, if two bases from left and right sides are same, we solve the exponent.

Therefore, [tex]\displaystyle \large{m^x = m^{10} \to \boxed{x=10}}[/tex]

______________________________

Summary

  Laws of Exponent

[tex]\displaystyle \large{a^m \cdot a^n = a^{m+n}}\\\displaystyle \large{\frac{a^m}{a^n} = a^m \div a^n = a^{m-n}}\\[/tex]

For what I demonstrate in my explanation only.

  Exponential Equation

When two bases from left side and right side are same, we can solve through exponents.

Examples:

[tex]\displaystyle \large{2^{x-3} = 2^{4}}\\\displaystyle \large{x-3=4}\\\displaystyle \large{x=4+3}\\\displaystyle \large{x=7}[/tex]

You can also substitute x-value in an equation to see if both sides are equal or not.

[tex]\displaystyle \large{2^{x-4} =2^3}[/tex]

Substitute x = 7 for check.

[tex]\displaystyle \large{2^{7-4} = 2^3}\\\displaystyle \large{2^3 = 2^3 \ \ \checkmark}[/tex]

  Logarithm

This is not necessary used in this question. This is mostly used for converting to exponential and more advanced mathematics.

[tex]\displaystyle \large{\log_a b^n = n\log_a b}\\\displaystyle \large{\log_a a = 1}[/tex]

Only from what I demonstrate in my explanation.

Ben and Landon took turns driving on a 820 mile road trip. Ben averaged 60 miles per hour and Landon averaged 56 miles per hour. The trip took them 14 hours. How many hours did Landon drive?

Answers

Answer:

See below!

Explanation:

distance = speed * timespeed = distance/timetime = distance/speed

equation for distance:

Lets Ben hours be x and Landon hours be y,

60x + 56y = 820 .........equation 1

equation for time:

[tex]\frac{60x}{60}+ \frac{56x}{56} =14[/tex]

x + y = 14 .........equation 2

Make x the subject:

60x + 56y = 820

x = (820 - 56y)/60 ..........equation 3

x + y = 14

x = 14 - y ........equation 4

Solve equation 3 and 4 simultaneously:

14 - y =  (820 - 56y)/6060(14 - y) = 820 - 56y840 - 60y = 820 -56y840 - 820 = -56y + 60y20 = 4yy = 5

             [ Therefore Landon drove 5 hours ]

Extra's further investigated:

if y = 5

x = 14 - yx = 14 - 5x = 9

              [ Therefore Ben drove 9 hours ]

Answer:

Landon drove 5 hours (and Ben drove 9 hours)

Step-by-step explanation:

Let B = number of miles Ben drove

Let L = number of miles Landon drove

Given The trip took them 14 hours

⇒ B + L = 14

Given, Ben averaged 60 miles per hour and Landon averaged 56 miles per hour. Ben and Landon took turns driving on a 820 mile road trip:

⇒ 60B + 56L = 820

Rewrite B + L = 14 to make B the subject, substitute into 60B + 56L = 820, and solve for L:

⇒ B = 14 - L

⇒ 60(14 - L) + 56L = 820

⇒ 840 - 60L + 56L = 820

⇒ 20 = 4L

⇒ L = 5

Therefore, Landon drove for 5 hours

Two punches are made from steel bar stock 9 7/16 inches long. If one punch is 4 1/64 inches long and the other is 4 3/32 inches long, how many inches of stock are wasted?
a. 1 1/16 inches
b. 1 5/16 inches
c. 1 15/64 inches
d. 1 21/64 inches

Answers

Answer:

d. 1 21/64 inches

Step-by-step explanation:

Add the lengths of the two punches.

4 1/64 + 4 3/32 = 4 1/64 + 4 6/64 = 8 7/64

Subtract the sum from the length of the bar stock.

9 7/16 - 8 7/64 = 9 28/64 - 8 7/64 = 1 21/64

Answer: d. 1 21/64 inches

The 1 15/64  inches of stock are wasted (option c).

To find out how much stock is wasted, we need to subtract the sum of the lengths of the two punches from the original length of the steel bar.

Original length of the steel bar = 9 7/16 inches

Length of the first punch = 4 1/64 inches = 4 + 1/64 inches

Length of the second punch = 4 3/32 inches = 4 + 3/32 inches

Total length of the two punches = (4 + 1/64) + (4 + 3/32) inches

Now, add the lengths of the two punches:

Total length of punches = 8 + 1/64 + 3/32 inches

Convert the fractions to a common denominator (64):

Total length of punches = 8 + 1/64 + 6/64 inches

Total length of punches = 8 + 7/64 inches

Now, subtract the total length of punches from the original length of the steel bar:

Wasted stock = 9 7/16 - (8 + 7/64) inches

Convert 9 7/16 to an improper fraction:

Original length of the steel bar = 9 * 16/16 + 7/16 = 151/16

Now, subtract the total length of punches:

Wasted stock = 151/16 - (8 * 16/16 + 7/64)

Wasted stock = 151/16 - (128/16 + 7/64)

Wasted stock = 151/16 - 130/16 - 7/64

Wasted stock = 21/16 - 7/64

Wasted stock = (21 * 4)/(16 * 4) - 7/64

Wasted stock = 84/64 - 7/64

Wasted stock = 77/64 inches

Now, let's simplify 77/64:

77/64 = 64/64 + 13/64 = 1 + 15/64 inches

Let use the other equation to manipulate data

3p + 2q = 7

:3p + 2 (2p - 7) = 7

:3p + 4p - 14 = 7

Given the function f(x)=3x^2+4x−4

find the following.

Step-by-step explanation:

Sometimes, it works well to find the general solution first, then use that to solve the specific problem. That's what we'll do here.

(b)

The average rate of change on the interval [x, x+h] is defined as ...

  m = (f(x+h) -f(x))/h

For the given f(x), this is ...

  [tex]m=\dfrac{((3(x+h)^2+4(x+h)-4)-(3x^2+4x-4)}{h}\\\\m=\dfrac{3x^2 +6xh+3h^2+4x+4h-4-3x^2-4x+4}{h}\\\\m=\dfrac{6xh+3h^2+4h}{h}\\\\\boxed{m=6x+4+3h}\qquad\text{average rate of change on $[x,x+h]$}[/tex]

__

(a)

Using the above result for the interval [-4. 0], we have x=-4 and h=4. The average rate of change on that interval is ...

  m = 6(-4) +4 +3(4) = -24 +4 +12 = -8

The average rate of change on [-4, 0] is -8.

_____

Additional comment

In the above, we worked the generic problem first. That way, we only needed to expand f(x+h)-f(x) once. If you're not terribly comfortable with doing algebra on literal expressions, sometimes it is more comfortable to work the numerical problem--as this question would have you do. This lets you get an idea of the kinds of operations that are involved and the way terms combine.

We note that the average rate of change is the instantaneous rate of change (derivative of the function) at the midpoint of the interval. That derivative is the value of m when h=0: 6x+4. The midpoint of the interval [-4,0] is x=-2, and the derivative there is 6(-2)+4 = -8, as above.
