The answer is -3.
Plug the x into the expression-
x=-1
x^2+7/x+5
-1^2+7/-1+5
-1+7/(-1)+5
-1-7+5
-8+5
-3
Your Welcome!!
(Hopefully they're all right)
Plug in -2 for y then solve for x. The answer should be x= -2
Answer:
y= -2x+23
Step-by-step explanation:
Subtract 2x over
Answer:
D
Step-by-step explanation:
A)
3(2) + 4(-2) = -2 2(2)-4(-2) = -8
6 - 8 = -2 4 + 8 = -8
Correct Incorrect
B)
3(6) + 4(-5) = -2 2(6) - 4(-5) = -8
18 - 20 = -2 12 + 20 = -8
Correct incorrect
C)
3(4) + 4(4) = -2
12 + 8 = -2
incorrect
D)
3(-2) + 4(1) =-2 2(-2) - 4(1) = -8
-6 + 4 = -2 -4 - 4 = -8
Correct Correct
