Answer:
-1
Step-by-step explanation:
F(x)=(4x-3)^-1(10))
(-4x+3(10))
(-4x(30))
i think that's how you would solve it i can't quite remember if you substitute the x with the 10 but if you do it would be
f(x)=4(10)-3
40-3
37
but im pretty sure it's the first way.
Divide 3/4 by 5/8
= 6/8 / 5/8 = 6/8 * 8/5 = 6/5
Unit rate is 1 to 6/5 = = 1 to 1.2
