Answer:
1 solution
Step-by-step explanation:
I think the answer is d. -11
Explanation:
Replace the variable x with 3 in the expression.
f(3)=-2•3-5
Multiply -2 by 3
f(3)=-6 -5
Subtract 5 from -6
f(3)= -11
Then the answer should be -11.
Answer:
6x + 1
Step-by-step explanation:
g(f(x))
f(x) = 3x - 1
g(f) = 2x + 3
= 2(3x - 1) + 3
= 6x - 2 + 3
= 6x + 1
Answer:
y = 1/2 x -4
Step-by-step explanation:
x - 2y = 8
Subtract x from each side
x -x - 2y = -x +8
-2y = -x+8
Divide each side by -2
-2y/-2 = -x/-2 +8/-2
y = 1/2 x -4
It depends on what its asking for and what dimension it is. If its 2D, the area is lengthXwidth, and perimeter you would add all the side lengths. If its 3D, volume is lengthXwidthXheigth.
