Answer:

6 or -6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

  • v^2 = 12^2 + 2(-3)(18)
  • v^2 = 144 + (-6)(18)
  • v^2 = 144- 108
  • v^2 = 36

Step 2: Take square root of both sides.

  • \sqrt{v^2} = ± \sqrt{36}
  • v =  ± \sqrt{36}
  • v = 6 or -6

Therefore, the answer is 6 or -6.

Use the graph below to answer questions 1 and 2.
saul85 [17]

Answer:

x-intercept is x = -4; y-intercept is y = -2

Step-by-step explanation:

1.

The zero or x-intercept is when the line touches the x-axis or horizontal line axis or is when y = 0.

x = -4

2.

The y-intercept is when the line touches the y-axis or vertical line axis or is when x = 0.

y = -2

-129 = -48 - n <br> Thank you
Flauer [41]

−129=−48−n

Simplify:

−129=−48+−n

Flip the equation.

−n−48=−129

Add 48 to both sides.

−n−48+48=−129+48

−n=−81

Divide both sides by -1.

−n/−1  =  −81/−1

n=81
