So first add the multiple choice together to get 15 and the true/false together to get 10. Then add those together to get 25. Since there was 15 multiple choice, divide 15 by 25 to get 3/5. This is .8 in decimal form and to convert it to a percent multiply it by 100 to get 80%. Hope this helps!

Which equation is equivalent to
marshall27 [118]
Answer:

C) 29x=5

reason:

first, distribute the parentheses
this will make your equation 8-20x=6-3+9x
simplify to get 8-20x=3+9x
add 20x to both sides to get 8=3+29x
subtract 3 from both sides to get 5=29x

Assume f is a one to one function of f(x)= 4-6x find f^-1(-32)​
OleMash [197]

Answer:

f^-1(-32)=6

Step-by-step explanation:

<u>Find the inverse of the function f(x)=4-6x:</u>

f(x)=4-6x

y=4-6x

x=4-6y

x-4=-6y

(x-4)/-6=y

-1/6x+2/3=y

y=-1/6x+2/3

f^-1(x)=-1/6x+2/3

<u>Plug in f^-1(-32) for f^-1(x) and simplify:</u>

f^-1(-32)=-1/6(-32)+2/3

f^-1(-32)=16/3+2/3

f^-1(-32)=18/3

f^-1(-32)=6
