Replace every x you see with 5 and do the math.

f(x) = 2x^2 + 2x - 3

f(5) = 2(5)^2 + 2(5) - 3

f(5) = 2(25) + 10 - 3

f(5) = 50 + 10 - 3

f(5) = 60 - 3

f(5) = 57

Complete the solution of the equation. Find the<br> value of y when x equals -8.<br> 3x + 5y = -59
Dafna1 [17]

Answer:

y = -7

Step-by-step explanation:

To answer this question, we must first plug in -8 for x:

3(-8) + 5y = -59

-24 + 5y = -59

+24           +24

5y = -35

/5      /5

y = -7

MariettaO [177]

Answer:

-2, 4, 36

Step-by-step explanation:

the equation should be:

(x+2)^2 + (y-4)^2 = 36

since the center is (-2, 3) and the radius is 6 units.

always remember:

C(h,k) = (x-h)^2 + (y-k)^2 = (radius)^2
