Triangle ABC is shown on the grid below.
Which value best represents the length of AB?
a 8 units
b 12 units
c 15 units
d 21 units
Answer:
15 units
Step-by-step explanation:
you have to use pythagoras to solve (c²=a²+b²)
AB is the longest side of the triangle which is c in the pythagoras
so counting the units for AC, you get 9 units, and CB you get 12 units
now solve for c in pythagoras
c²=9²+12²
c = 15 units
list the sides of the triangle from smallest to largest.

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?
Answer:
See below!
Explanation:
distance = speed * timespeed = distance/timetime = distance/speedequation 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
someone please give a step by step way on how to solve this problem
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.

Graph this line using the slope and y-intercept: y = 1/8x + 4
(1/8 is a fraction)
Answer:
Two points, (0,4) & (8,5)
Step-by-step explanation:
In this equation, we can easily find the first point by looking at the +4 in this equation. This should automatically signal to you that the point is (0,4)
Now, we have to look at the 1/8x in the equation.
This 1/8 means that the slope is 1/8!
Now we use the slope and to rise/run to find our next point
We go up 1 from 4 (this is the rise) to get to 5 on the y-axis
Next, we go over 8 horizontally to get to 8 for your x-axis point.
So therefore, our next point is, (8,5)
You can use this rise/run system infinitely and is very useful

The figure is made up of 2 rectangles and 2 right triangles
What is the area of this figure
132 units^2
156 units^2
168 units^2
216 units^2
Answer:
total area = 132 units²
Step-by-step explanation:
Area of a rectangle = width x heightArea of a triangle = 1/2 x base x height
Area of largest rectangle = 4 x 15 = 60 units²
Area of smallest rectangle = 4 x 6 = 24 units²
Area of largest triangle = 1/2 x (15 - 6) x (4 + 4) = 36 units²
Area of smallest triangle = 1/2 x 6 x 4 = 12 units²
Total area of the figure = sum of areas of 2 rectangles and 2 triangles
⇒ area = 60 + 24 + 36 + 12 = 132 units²

What is the value of x?
Enter your answer as a decimal in the box.
Answer:
[tex]x = 22.5[/tex]
Explanation:
Given Sides:
HB = 6HD = 6+15 = 21HM = 9HT = 9 + x-----------------------------
using all these sides, create similarities equation:
[tex]\frac{HB}{HD} = \frac{HM}{HT}[/tex]
[tex]\frac{6}{21} = \frac{9}{9+x}[/tex]
[tex]6(9+x) = 9(21)[/tex]
[tex]54 + 6x = 189[/tex]
[tex]6x = 189 - 54[/tex]
[tex]6x = 135[/tex]
[tex]x = \frac{135}{6}[/tex]
[tex]x = 22.5[/tex]
The function y = f (x) is linear.
Given f-¹ (0) = 3 and f (1) = - 4, find the formula of
f (x) and f-¹ (x)
Answer:
[tex]f(x)=2x-6[/tex]
[tex]f^{-1}(x)=\dfrac{x+6}{2}[/tex]
Step-by-step explanation:
Using slope-intercept form of linear function: [tex]y = mx + b[/tex]
[tex]\implies f(x)=mx+b[/tex]
[tex]\textsf{if} \ \ f(1) = -4[/tex]
[tex]\implies m + b=-4[/tex]
[tex]\implies b = -4-m[/tex]
Find inverse of slope-intercept form:
swap x and y: [tex]x = my + b[/tex]
Make y the subject:
[tex]\implies x - b = my[/tex]
[tex]\implies y = \dfrac{x-b}{m}[/tex]
[tex]\implies f^{-1}(x) = \dfrac{x-b}{m}[/tex]
[tex]\textsf{if} \ \ f^{-1}(0) = 3[/tex]
[tex]\implies \dfrac{0-b}{m}=3[/tex]
[tex]\implies b=-3m[/tex]
[tex]\textsf{equation 1:} \ \ b = -4-m[/tex]
[tex]\textsf{equation 2:} \ \ b=-3m[/tex]
Equate the equations and solve for [tex]m[/tex]:
[tex]\implies b=b[/tex]
[tex]\implies -4-m=-3m[/tex]
[tex]\implies -4=-2m[/tex]
[tex]\implies m=2[/tex]
Substitute found value for [tex]m[/tex] into one of the equations and solve for [tex]b[/tex]:
[tex]b = -4-2=-6[/tex]
Substitute found values of [tex]m[/tex] and [tex]b[/tex] into equations for [tex]f(x)[/tex] and [tex]f^{-1}(x)[/tex]:
[tex]f(x)=2x-6[/tex]
[tex]f^{-1}(x)=\dfrac{x+6}{2}[/tex]

Answer:
1st row = 10 = y
2nd row = 12 = y
3rd row = 18 = y
4th row = 22 = y
Step-by-step explanation:
Given:
y = 4x + 6
since the y-intercept is 6, we know that when the input value(x) is equal to 0, the output value(y) is equal to 6.
so now we plug in the equation for each row,
starting with the first one.
in the first row it says x is equal to 1 so the equation would look like this:
y = 4(1) + 6
simplified the equation to get
y = 4 + 6 = 10
meaning for the first row, y = 10!
since the x value is constant, and only goes up by 1 each row, this means we can just add 4 more each time.
However, I am going to write the equation for each row anyways.
Second row:
y = 4(2) + 6
simplifys into
y = 8 + 6 = 12
y = 12
Third row:
y = 4(3) + 6
simplifys into
y = 12 + 6 = 18
y = 18
Fourth row:
y = 4(4) + 6
simplifys into
y = 16 + 6 = 22
y = 22
So to recap, the answers to each row are...
1st row = 10 = y
2nd row = 12 = y
3rd row = 18 = y
4th row = 22 = y

Write the equation of the line in fully simplified slope-intercept form.
Answer:
y = - 6x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 10) and (x₂, y₂ ) = (- 1, - 2) ← 2 points on the line
m = [tex]\frac{-2-10}{-1-(-3)}[/tex] = [tex]\frac{-12}{-1+3}[/tex] = [tex]\frac{-12}{2}[/tex] = - 6
the line crosses the y- axis at (0, - 8 ) ⇒ c = - 8
y = - 6x - 8 ← equation of line
