Answer:
False, true
Step-by-step explanation:
A str. line on a coord. plane does NOT always represent a function. The vertical line x = 6, for example, represents a case in which there are more than one y-values for each x value. FALSE.
y = 2x + 1 represents a function. For any input, x, the equation y = 2x + 1 returns exactly one y value. TRUE
Answer:
2 1/6
Step by step: subtract 1 1/2 from 3 2/3
Answer: 9x - y = -1
y = 10
10x=180
x=18
Angle B: 18(6)=108
Angle A: 18(2)=36
Angle C: 18(2)=36
**Angle C would equal 36**
You can't factor anything out of this. At least I don't think
