Answer:
f⁻¹(x) = (4x)/5
Step-by-step explanation:
f(x) = 2x - 3x/4.
Assume y=f(x). Therefore:
y = 2x - 3x/4.
Make x the subject in the above equation.
y = (2x(4) - 3x)/4.
y = 5x/4.
4y = 5x.
(4y)/5 = x.
x = (4y)/5.
Therefore:
f(y) = (4y)/5.
Replace y with x.
f⁻¹(x) = (4x)/5.
Therefore, the inverse of f(x) = 2x - 3x/4 is f⁻¹(x) = (4x)/5!!!
Answer:
whats the question
Step-by-step explanation:
If a circle has a radius of 
, it is true that: <u>D. The </u><u>circumference </u><u>of the </u><u>circle </u><u>is </u>
<u />
<em><u>Recall the following about a </u></em><em><u>circle</u></em><em><u>:</u></em>
- Area of a circle =
- Circumference of a circle =
If a circle has a radius of 
, the area and circumference of the circle would be the following:
- Area of a circle =
- Substitute
into the area formula
- Circumference of a circle =
- Substitute into the circumference formula
Therefore, if a circle has a radius of , it is true that: <u>D. The </u><u>circumference </u><u>of the </u><u>circle </u><u>is </u><u />
