Answer:
see explanation
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 3x - 2 ( add 2 to both sides )
y + 2 = 3x ( divide both sides by 3 )
[tex]\frac{y+2}{3}[/tex] = x
change y back into terms of x with x = [tex]f^{-1}[/tex] (x)
[tex]f^{-1}[/tex] (x) = [tex]\frac{x+2}{3}[/tex]
To evaluate [tex]f^{-1}[/tex] (13) substitute x = 13 into [tex]f^{-1}[/tex] (x) , that is
[tex]f^{-1}[/tex] (13) = [tex]\frac{13+2}{3}[/tex] = [tex]\frac{15}{3}[/tex] = 5
3x - 5 = 1 what is the value of x
Answer:2

Juan can walk to school, a distance of 0.75 mile, in 8 minutes. Assuming he walks at a constant rate, write the linear equation that represents the situation.
helpppp
Write an equation that you could subtract from 4x+3y=-7 to eliminate a variable. Then solve the system.
x= 7/4 - 3/4
you just have to subtract on variable and then put it on the other side, eventually you will have to divide it all by 4, which you can't do, so it ends up as a fraction:)

according to the property √a/√b=√a/b, which choice is equivalent to the quotient below? √72/2
According to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex], [tex]\sqrt{\frac{72}{2} }[/tex] = 6.
What is square root?The square root of a number is the value of power 1/2 of that number. In other words, it is the number whose product by itself gives the original number.
Given
[tex]\sqrt{\frac{72}{2} }[/tex]
= [tex]\sqrt{36}[/tex]
= 6
According to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex]
[tex]\sqrt{\frac{72}{2} }[/tex] = [tex]\frac{\sqrt{72} }{\sqrt{2} }[/tex]
= [tex]\frac{6\sqrt{2} }{\sqrt{2} }[/tex]
= 6
Thus, according to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex], [tex]\sqrt{\frac{72}{2} }[/tex] = 6.

Please someone help me quick!!!! It's about Domain and range, Please! Anyone!
Answer:
Step-by-step explanation:
They already said the domain of f(x) is x≥0.
The smallest value of f(x) is f(0) = 9.
Range of f(x) is y≥9.
The radicand of a square root must be non-negative, so the domain of f⁻¹(x) is x≥9.
The range is y≥0.
