The answer of all of this is 18 because 18.1 months so if you do the math you get 18-7x+20^2
Answer:
x = 1/4
Step-by-step explanation:
-7x - (-5-x) = -9(2x-1) -1
-7x + 5 + x = -18x + 9 - 1
combine like terms:
-6x + 5 = -18x + 8
add 18x to each side of the equation:
12x + 5 = 8
subtract 5 from each side:
12x = 3
divide both sides by 12:
x = 3/12 = 1/4
2, 6, 8) → D
each element in the domain ( - 1, 3, 5) maps to exactly one value in the range (2, 6, 8)
"A" is the correct answer
