Evaluate. Use x=-2 y=6
5x-3y

-28

Step-by-step explanation:

x=-2 y=6

5x-3y

5(-2) -3(6)
= -10 -18
= -28

-28

Step-by-step explanation:

Basically, this question is asking you to substitute the variables (x and y in this case) with numbers to solve the equation. Before we solve, let's replace those variables. So, if x = (-2), and y = 6, then:

5(-2) - 3(6).

We need to solve the equation from left to right. But we can't solve for the subtraction yet, because we need to solve for the multiplication first. So:

5 x (-2) = (-10) and 3 x 6 = 18.

Now we can subtract.

-10 - 18 = (-28).

Let me know if you have any more questions, I hope that this helps.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
