Answer:
z² = x² + y²
Step-by-step explanation:
Given
z² - y² = x² ( isolate z² by adding y² to both sides )
z² = x² + y²
Answer:
Step-by-step explanation:
A proportion is being directly related to something, meaning that there is just multiplication or division (just a coefficient in front of the x-coordinate, nothing more).
In a graph, a proportional graph is a graph that goes straight through the origin.

Answer:
x = 8.7
Step-by-step explanation:
Reference angle = 30°
Opposite side length = x
Adjacent side length = 15
Apply trigonometric function, TOA:
Tan 30° = Opp/Adj
Plug in the values
Tan 30° = x/15
Multiply both sides by 15
15*Tan 30° = x
8.66025404 = x
x = 8.7 (nearest tenth)
Answer:
-16
Step-by-step explanation:
4a+(-8)
4(-2)+(-8)
