Answer: -12r-12

Step-by-step explanation: There is no equals sign so you can't solve it but you can simplify it. You start out with -3(4r-8)-36. Then, you use PEMDAS. (-3×4r)+(-3×-8)-36. Then, it turns into -12r×+24-36. You just continue to simplify until you can't anymore. You end up with -12r-12.

Answer:-5

Step-by-step explanation:

You need to distribute on both sides so u get

9c-15=20-2c

Move variable to left side and change the sign

-9c+2c-15=20

Move constant to right side and change the sign

-9c+2c=20+15

Connect like terms

-7c=35

Divide

Here's a graph of a linear function. Write the equation that describes that function. (Express it in slope-intercept form.)

Answer:

$y=\frac{1}{2}x+4$

Step-by-step explanation:

The equation of a linear function in a slope-intercept form is written as

$y=mx+q$

where

m is the slope of the line

q is the y-intercept

We proceed as follows. First of all, we find the y-intercept, which is the value of y at which the line touches the y-axis.

From the graph, we see that this occurs at y = 4, therefore the y-intercept is

$q=4$

Now we have to find the slope. We do that by choosing two points along the line, with coordinates $(x_1,y_1)$ and $(x_2,y_2)$ and by using the equation
