Answer:

B

Step-by-step explanation:

To evaluate (f ○ g)(- 4), first evaluate g(- 4) then substitute this value into f(x)

g(- 4)  = 3(- 4) - 5 = - 12 - 5 = - 17, then

f(- 17) = 4(- 17) + 7 = - 68 + 7 = - 61 → B

PLZ ANSWER ASAP! What is the solution of the system of equations? {7/2x−1/2y=9/2 3x−y=5 Enter your answer in the boxes.
Reil [10]

\frac{7}{2} x -  \frac{1}{2} y =  \frac{9}{2}  same \: as \: 7x - y = 9
7x-y=9
3x-y=5 (multiply by -1 both sides of the equation)

7x-y=9
-3x+y=-5 (now add both equations)

7x-3x-y+y=4
4x=4 (divide by 4 both sides of the equation)

x=1

y=3x-5=3×1-5=-2

y= -2

answer: x=1, y=-2
