Answer:
I think 37.5
Step-by-step explanation:
I think 37.5 because 40% of x=75 is 30, and 50% of 75 is 37.5, I suppose!
SORRY IF WRONG ;c
(Edit) wAIT tHE AaNSWER HAS TO BE A PERCENTAGE?
Well then idk
y=-2x-13
y-y1=m(x-x1)
y-(-13)=-2(x-0)
y+13=-2x
separate the x from the numbers it will make the equation easier
