The first 3 are functions as their x coordinate (number on the left side of the parentheses) is not repeated in any of the other parentheses
Answer:
x - 4
Step-by-step explanation:





Answer:
x = 40
Step-by-step explanation:
x + 100 + x = 180 {Straight line angles}
2x + 100 = 180 {subtract 100 from both sides}
2x = 180 - 100
2x = 80 {Divide both sides by 2)
x = 80/2
x = 40
Answer:
B)
.
Step-by-step explanation:
The vertex form of the equation is given by
.
We plug in the vertex to obtain:
.
Since the graph passes through (5,5) and (9,5), they must satisfy its equation.
.
.

Divide both sides by 4.

Therefore the equation is:
.
