$12 per hour

He works 28 hours.

Multiply the hours by the money he makes per hour.

28 * 12 = $336

you would simply multiply $12 by 28, and you get $336.

What are the x and y intercepts for the equation 3y=12+2x

Finger [1]

Answer:

Step-by-step explanation:

Given that,

3y=12+2x

To find the x-intercept will set y=0 because, at the intercept of x, the value of y is 0

Then, y=0

3y=12+2x

3(0)=12+2x

0=12+2x

2x=-12

divide both sides by 2

x=-12/2

x=-6

Also, to get the y-intercept, let set x=0, because, at the intercept of y, x = 0

3y=12+2x

3y=12+2(0)

3y=12

Divide both sides by 3

y=12/3

y=4

So, y-intercept 4

Also, the x-intercept is -6

Fina Question 1. Write the equation of the line that goes through the points (-2,1) and (4,2)

SpyIntel [72]

If we have two coordinates that are in the line we can find the slope with this equation:

$m=\frac{y_2-y_1}{x_2-x_1}$

So now we replace the coordinates so:

$\begin{gathered} m=\frac{2-1}{4-(-2)} \\ m=\frac{1}{6} \end{gathered}$

Now with the slope and any point we can find the intercept in the y axis by replacing x=0 so:

$\begin{gathered} \frac{1}{6}=\frac{y-2}{0-4} \\ -\frac{4}{6}=y-2 \\ -\frac{2}{3}+\frac{6}{3}=y \\ \frac{4}{3}=y \end{gathered}$

So the equation is:

$y=\frac{1}{6}x+\frac{4}{3}$

Find the average rate of change of f(x)= x^2-4x from x of one =5 to x of two =9

ICE Princess25 [194]

The rate of change of function is: 10

Further explanation:

The formula for rate of change is:

$Rate\ of\ change = \frac{f(x_2)-f(x_1)}{x_2-x_1}$

Given

$f(x) = x^2-4x\\x_1 =5\\x_2=9\\So,\\f(x_1) = f(5) = (5)^2-4(5)\\=25-20\\=5\\f(x_2) = f(9) = (9)^2-4(9)\\=81-36\\=45$

Putting the values in the formula:

$Rate\ of\ change = \frac{f(9)-f(5)}{9-5}\\=\frac{45-5}{9-5}\\=\frac{40}{4}\\=10$

The rate of change of function is: 10
