8(x+2)
8x+16
When you multiply the two together, you get the simplified version.

If you would like to solve 8 * (x + 2), you can do this using the following steps:

8 * (x + 2) = 8 * x + 8 * 2 = 8 * x + 16

The correct result would be 8 * x + 16.

Answer:

f'(1) exists: f'(1) = -2
f'(0) DNE

Step-by-step explanation:

The function is continuous for x > 0 . The derivative is defined on that interval and is equal to ...

f'(x) = -2x . . . . . for x > 0

Then at x = 1, the derivative is ...

f'(1) = -2(1)

f'(1) = -2

The function has a jump discontinuity at x=0, so the derivative does not exist at that point. A condition for the existence of the derivative is that the function is continuous at the point of interest.

What is the equation of a line perpendicular to the line given by y = (3/7)x+ 9

Nikolay [14]

Answer:

B) y = (-7X/5) + 4

Step-by-step explanation:

Recall two lines are perpendicular if their slopes are negative reciprocals (5/7 goes to -7/5).

Assuming in the form y = mx + b:

Solving for b:

-7/5(-5) + x = 11

(5's & negatives cancel out...)

7 + x = 11

x = 4

y = -7/5x + 4

the width of a rectangle is 15 units less than the length. if the area is 76 square units, then find the dimensions of the recta

Lelu [443]

W = L - 15
WL = 76

(L-15)L = 76

L^2 - 15L - 76 = 0
(L-19)(L+4) = 0

L = 19 or -4
Since a length cannot be negative, the length must be 19 units.
The width is 19-15=4 units.
