Solve: −8x−7/ 3 =11
VladimirAG [237]

Answer: x=-\frac{5}{3}

Step-by-step explanation:

Given the equation -8x-\frac{7}{3}=11, you need find the value of the variable x.

Then, you have to solve for x:

 Add \frac{7}{3} to both sides of the equation.

Divide by -8 to both sides of the equation.

Once you do this proccedure, you will get the value of the variable x.

Then:

-8x-\frac{7}{3}+\frac{7}{3}=11+\frac{7}{3}

-8x=\frac{40}{3}\\\\\frac{-8x}{-8}=\frac{\frac{40}{3}}{-8}\\\\x=-\frac{5}{3}

Given f(x)=8x^5, find f^-1(x) <br> Then state whether f^1(x) is a function.
irina1246 [14]

Answer:

f^-1(x) = (x/8)^(1/5) is a function

Step-by-step explanation:

The inverse of a function is the function reflected across the line y=x. This results in the coordinate points (x,y) of the function becoming (y,x) for the inverse function. Algebraically to find the inverse, switch the x and y locations and solve for y.

y = 8x^5

x = 8y^5

x/8 = y^5

(5)√(x/8) = y

This is a fifth root of (x/7) also written in exponents as y = (x/8)^(1/5).

This is a function. While it appears not to be a function because the middle portion over the origin appears vertical, it is a function because the middle portion over the origin is changing and graphing software shows it has no input with more than one output. Without graphing software you would rule it is not a function.

Solnce55 [7]
Because the design is scaled by 3, the new dimensions are 9*3 X 12*3 = 27 X 36

Since the dimensions are 27 X 36, the area is equal to 27*36 = 972 square inches.
