bryan runs 2 miles every 40 minutes. At this rate, how many minutes did Bryan run if he ran 8 miles?

Answer:

y = 2x + 2

Step-by-step explanation:

First solve for the slope using [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

[tex]\frac{8-2}{3-0}[/tex] = 2

Plug the slope into the slope intercept form equation y = mx + b

y = 2x + b

To solve for b, plug in any (x, y) point on the table.

2 = 2(0) + b

2 = b

Now you can plug the b value into your equation.

y = 2x + 2

Step-by-step explanation:

8x-7+3x-11=180

11x-18=180

x=18

2y+23=4y+8

2y=15y=15/2

4y+8=3z²-5

y=15/2=> 30+8=3z²-5

43=3z²

z=±√(43/3)

Answer:

120 gallons of gasoline needs 180 ounces of oil

Step-by-step explanation:

Since the label for the chain saw reads to mix 3 ounces of oil with 5 gallons of gasoline, it means we have a ratio of 3 ounces of oil to 5 gallons of gasoline. That is

3 ounces of oil = 5 gallons of gasoline

Using the the unity method, by dividing both sides by 5,

3/5 ounces of oil = 1 gallon of gasoline.

So, for 120 gallons of gasoline, we have

120 × 1gallon of gasoline = 120 × 3/5 ounces of oil

So, 120 gallons of gasoline = 60 × 3 ounces of oil

So, 120 gallons of gasoline = 180 ounces of oil

So, 120 gallons of gasoline needs 180 ounces of oil

Hi I had the same question on my test and the answer is  c or b

The solution is, The initial payment will be  $437.50.

Here, we have,

given that, Steven has obtained a $105,000 5/1 30-year ARM at 5%. During the first 3 years, he has an option of paying interest only.

so, we get,

Steven has obtained a $105,000, 5/1 30-year ARM at 5%.

During the first 3 years, he has an option of paying interest only.

So, it is simple interest.

Simple interest is given as :

I = p*r*t/100

here, p = 105000

r = 5%

t = 30

Putting values in formula:

= $157500

As this is interest for 30 years or 360 months.

So, for initial interest we will divide the interest with 360.

$157500/360

≈$437.50

Therefore, the initial payment will be $437.50

Answer:

[tex]T(x)=84-2x[/tex]

Step-by-step explanation:

Linear Modeling

The initial temperature outside is 84 degrees.

We are told the temperature drops 2 degrees every hour.

Let's call x to the number of hours elapsed. After x hours, the temperature would have dropped by 2x degrees, since it's a rate of 2 degrees per hour.

That drop is subtracted from the initial temperature to produce the linear model as follows:

[tex]\mathbf{T(x)=84-2x}[/tex]

This is the linear equation that represents the described situation.

Answer:

slope of the line is 50

Step-by-step explanation:

The slope of a line (gradient) is determined by the rise/run so

(y2 - y1) / (x2 - x1)

We simply substitute in our coordinates and solve. So:

(4000 - 3000) / (60 - 40)

= 1000 / 20

= 100/2 = 50

Gradient is 50

Answer:

$1.25 dollars per day added to the coin jar

Step-by-step explanation:

the given equation is: 56 – 4y = –5x

we can rewrite it:

4y = 56 + 5x

y = (56 + 5x) / 4

y = 14 + ⁵/₄x

the slope of the equation is ⁵/₄, which gives us how much money is added into the coin jar every day. We can write ⁵/₄ as 1.25 or $1.25 dollars per day added to the coin jar

Answer:

The values of k that make the given equation having imaginary roots are:

k < -18, or (-∞,-18).

Step-by-step explanation:

Nature of the Roots of a Quadratic Equation

The standard representation of a quadratic equation is:

[tex]ax^2+bx+c=0[/tex]

where a,b, and c are constants.

Solving with the quadratic formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

The expression:

[tex]d=b^2-4ac[/tex]

Is called the discriminant. The discriminant determines the nature of the roots of a quadratic equation as follows:

If d=0, there is only one real root.

if d>0, there are two different real roots

if d<0, there are two different imaginary (complex) roots

We are given the equation:

[tex]-2x^2+12x+k=0[/tex]

Comparing with the standard quadratic equation, we have:

a=-2, b=12, c=k

Calculating the discriminant:

[tex]d=12^2-4(-2)k[/tex]

[tex]d=144+8k[/tex]

If the equation has imaginary roots, then d<0, thus:

144 + 8k < 0

Subtracting 144:

8k < -144

Dividing by 8:

k < -18

The values of k that make the given equation having imaginary roots are: k < -18, or (-∞,-18).

The inverse of a function reverses the operation of a function

The statement that provides the correct analysis of Maggie's claim is the following option;

Maggie's claim is incorrect because when g(x) is substituted into every occurrence of x in f(x), f(g(x)) = x - 8; therefore, g(x) is not the inverse of f(x)

Question: The functions in the question are presented as follows;

[tex]g(x) = \dfrac{x}{3} - 4[/tex]

f(x) = 3·x + 4

Required:

The statement that provides a correct analysis of Maggie's claim

Solution:

The inverse of f(x) is found as follows;

y = 3·x + 4

[tex]x = \dfrac{y - 4}{3}[/tex]

Therefore;

[tex]f^{-1}(x) = \dfrac{x - 4}{3}[/tex]

The inverse of a function above was found by making x the subject of the

function f(x), therefore, when the inverse f⁻¹(x) is substituted into all

occurrence of x in f(x), we get x

However, when g(x) is substituted into every occurrence of x in g(x), we get;

[tex]f \left (g(x) \right) = 3 \times \left (\dfrac{x}{3} - 4 \right)+ 4 = x - 8 \neq x[/tex]

Therefore, the given function g(x) is not the inverse of the function f(x) and the correct option is as follows;

Maggie's claim is incorrect because when g(x) is substituted into every occurrence of x in f(x), f(g(x)) = x - 8; therefore, g(x) is not the inverse of f(x)
