Answer:
a = -2
Step-by-step explanation:
Subtract 10 from both sides:
7a + 10 - 10 = 2a - 10
Simplify:
7a = 2a - 10
Subtract 2a from both sides:
7a - 2a = 2a - 10 - 2a
Simplify:
5a = -10
Divide both sides by 5 and simplify:
a = -2
Answer:
yes
Step-by-step explanation:
It is a parabola, Every y has a unique x value
If the number was x, then you could write the expression x-5 since you show five less or subtracted from the number. Hope this helps.
(8z - 10) ÷ (-2) + 5(z - 1) = 8z - 10 ÷ -2 + 5z - 5 = 8z + 5 + 5z - 5 = 13z
