Answer:
C
Step-by-step explanation:
To solve, use inverse operations:

Now we solve for both +/- 7.
x+6=7
x=1
x+6=-7
x=-13
Answer:
(-5-3/2,3+1/2)
(-13/2,7/2)
option A is correct
Step-by-step explanation:
Hope it helps
The correct answer is B because after you simplifiy the expression, you would get that answer:
7x + 3y - 2 + 6x + 1 + y^2
combine all the like terms to one side first
7x + 6x - 2 + 1 + y^2
then simplify
13x - 1 + y^2 or y^2 + 3y + 13x - 1
1.5 hours=60+30=90 minutes
30 pages : 90 minutes = 0.3 pages/minute
5x-1=19
1st you add the one over to the 19 and you'll get 20
then you do 5x=20
divide the 5x over to the 20 and your final answer is 4.
