What is the inverse of the function f(x) = 1/4x - 12?

Answers

Hello,

1) if the equation is
y=1/4 * x-12 then x=1/4 y-12==>1/4y=x+12==>y=x/4+3

2) if the equation is
y=1/(4x-12) then x=1/(4y-12)==>4y-12=1/x==>4y=1/x+12==>y=1/(4x)+3

5/13t=-9 how to solve

Answers

Well, first, we need to get rid of that fraction by multiplying the whole equation by 13 to cancel out the fraction.
13(5/13t=-9)
5t=-117
And now, we have to divide the whole equation by 5 to get the t by itself.
(5t=-117)/5
t=-117/5
Hope it Helps!  :)

Which expression gives the volume of a sphere with radius 8?A. 4(83)
B. (82)
C. (83)
D. 4(82

Answers

Given:
radius = 8

Volume of a sphere = 4/3 * π * r³

V = 4/3 * 3.14 * 8³
V = 1.33 * 3.14 * 512
V = 2,138.21 cubic unit
The volume of a sphere is (4/3)π(r^3)

Here r = 8

Then the expression for this sphere is 4π(8^3)/3 = 4*1.05 (8^4) ≈ 4(8^3)

You have to check the options..
