Plug in 3 to x:
f(x) = 3³ - 7
Solve:
f(x) = 3³ - 7
f(x) = 3 · 3 · 3 - 7
f(x) = 9 · 3 - 7
f(x) = 27 - 7
f(x) = 20

Answer:
The answer is A
Step-by-step explanation:
The rectangular has a height of 4 unit and has a width of 7 units. Area of the rectangular is:

28 unit square.
The point of (2,2) is on the middle height of rectangular shape. The point has 2 unit distance to base and ceiling of the rectangular.
The line y=2 is passing thought on (2,2) and also divides rectangular into two rectangular which have 14 unit square area.
Therefor, the slope is 0
Answer:
z score for Maria is higher than Stephanie
Step-by-step explanation:
for Stephanie

Answer:
v = √(
)
Step-by-step explanation:
E=1/2mv²
v² = (
)
v = √(
)
Using the first equation:
4x = y + 3 ---> y = 4x - 3
We then substitute this into the second equation:
7x - 9(4x-3) = -2 ---> 7x - 9x + 27 = -2 ---> -2x = -29 ---> x = 14.5
