Answer:
y = -7/4 x + 5
Step-by-step explanation:
(54000 ÷ 6 ÷ 10 − 30 ∙ 6) ∙ (10 ∙ 20 ∙ 5 ∙ 10 − 99 ∙ 101) = (980 - 180) · (10000 - 9999) = 720 · 1 = 720
Pretty sure that the answer is B because if you plug in x+1 into 4x^2 you get 4(x+1)^2
-4= Contraction
2.5=Expansion
2/3= Contraction
-3/4= Contraction
Best way to solve this, if the scale factor is less than one, is a contraction. If it is greater than one, than it is an expansion.
