Answer:

26.36, 52.72, 65.90

Step-by-step explanation:

write the formula

2x + 4x + 5x = 145

add all the xs together

11x = 145

find x

11x ÷ 11 = 145 ÷ 11

x = 13.1818

subsitute the value of x to 2x, 4x, and 5x to find the side lengths

2(13.1818) = 2.3636

4(13.1818) = 52.7272

5(13.1818) = 65.909

Inverse Function In Exercise,analytically show that the functions are inverse functions.Then use the graphing utility to show th
Anna [14]

Step-by-step explanation:

We need to show whether

f^{-1}(x) = g(x)

or

g^{-1}(x) = f(x)

so we'll do either one of them,

we'll convert f(x) to f^-1(x) and lets see if it looks like g(x).

f(x) = e^x - 1

we can also write it as:

y = e^x - 1

now all we have to do is to make x the subject of the equation.

y+1 = e^x

\ln{(y+1)} = x

x=\ln{(y+1)}

now we'll interchange the variables

y=\ln{(x+1)}

this is the inverse of f(x)

f^{-1}(x)=\ln{(x+1)}

and it does equal to g(x)

g(x)=\ln{(x+1)}

Hence, both functions are inverse of each other!

This can be shown graphically too:

we can see that both functions are reflections of each other about the line y=x.

Solve system if equations
Alexandra [31]

Answer:

(2, 9)

x = 2

y = 9

Step-by-step explanation:

To solve this system, we can either use substitution or graph it. I will be showing how to graph it.

To solve by graphing, we graph both of the equations and find the point at which the lines intersect.
