Answer:
y=3x- 3/2
Step-by-step explanation:
4.2x−1.4y=2.1
Subtract 4.2x from each side
4.2x-4.2x−1.4y=-4.2x+2.1
-1.4y = -4.2x +2.1
divide each side by -1.4
-1.4y/-1.4y = -4.2x/ -1.4 +2.1/-1.4y
y=3x- 3/2
I believe it’s 9 but unsure sorry
The formula for direct variation is y = kx<span> where k </span>≠ 0
y = 9/x is an inverse relation
The correct answer should be A because you have to have a common denominator in order to solve so you take 5/6x and 4/6x and solve.
