Answer:
the first step is wrong
it should be 4(x-4)/(x+1)(x-4) - (x+2)/(x-4)(x+1)
Answer:
80
Step-by-step explanation:
80 divided by 1/2 = 40 therefore 40 is 50% of 80
Direct variation is of the form y=kx. We are given the point (8, -4) so we can solve for k, the constant of variation...
-4=8k, divide both sides by 8
-4/8=k
k=-0.5, so our equation is:
y=-0.5x,
