Answer:

f(-5)=90

Step-by-step explanation:

We are given the function:

f(x)=4x^2+x-5

In order to find f(-5), substitute -5 for <em>x: </em>

<em />f(-5)=4(-5)^2+(-5)-5<em />

Evaluate:

f(-5)=4(25)-10=100-10=90

Therefore:

f(-5)=90

V125BC [204]

Answer:

B and E

Step-by-step explanation:

A. 8x = 2

8(4) = 2

32 = 2

B. 19 + x = 23

19 + 4 = 23

23 = 23

C. 40/x = 5

40/4 = 5

10 = 5

D. -3x = 12

-3(4) = 12

-12 = 12

E. x - x - x - x = -8

4 - 4 - 4 - 4 = -8

0 - 4 - 4 = -8

-4 - 4 = -8

-4 + (-4) = -8

-8 = -8
