Step-by-step explanation:
∵ DE∥FG
∴∠EDF=∠GFH
∵∠DFE=180º-∠DEF-∠EDF
and ∠FHG=180º-∠FGH-∠GFH
∴∠DFE=∠FHG
<span>3(2y - 4) = 8y + 9 - 9y
Distribute 3:
6y - 12 = 8y + 9 - 9y
Combine like terms:
6y - 12 = -y + 9
Add y to both sides:
7y - 12 = 9
Add 12 to both sides:
7y = 21
Divide both sides by 3:
y = 3</span>
F^-1 (x)= sqrt(5x)/ sqrt(5x), -sqrt(5x)/5 is the inverse of the function y=5x^2
