Answer:

Step-by-step explanation:
On a unit circle, the only points where y =
have an x coordinate of
or
. Since only one of those is an option, the answer is
.
10x - 3 = x + 2 + 2x - 1
10x - 3 = 3x + 1
-3x on both sides
7x - 3 = 1
-1 on both sides
7x - 4
(Check 7x - 4 by adding them all up to equal 10x - 3)
x + 2 + 2x - 1 + 7x - 4 = 10x - 3
combine liked terms
10x - 3 = 10x - 3
Answer:
D) 7x - 4
Step-by-step explanation:
1/5x-12=0
1/75-12=0
1-900=-899/75
