The expression Joelle should use to find the tip amount is 38(0.20).

<h2>Expression </h2>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.  

<h2>Given to us</h2>

Percentage tip of Joelle hairdresser = 20%,

Joelle's haircut costs = $38,

<h3>Percentage Conversion</h3>

As we know that  percentage shows a part of something, therefore,

20\%\ of\ \$38\\= 20\% \times 38\\\\= \dfrac{20}{100}\times 38\\\\= 0.2 \times 38

Hence, the expression Joelle should use to find the tip amount is 38(0.20).

knowing the points a(1, 6), b(−5, −2), c(−1, −5), and d(5, 3), and that segment ab is parallel to segment cd, what is the length
denpristay [2]
Length of a line given two points is given by:
 l= &#10;\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}  \\ AB= \sqrt{(-5-1)^2+(-2-6)^2}  \\ = &#10;\sqrt{(-6)^2+(-8)^2}  \\ = \sqrt{36+64}  \\ = \sqrt{100}  \\ =10 \\  \\ &#10;CD= \sqrt{(3-(-5))^2+(5-(-1))^2}  \\ = \sqrt{(3+5)^2+(5+1)^2}  \\ = &#10;\sqrt{8^2+6^2}  \\ = \sqrt{64+36}  \\ = \sqrt{100}  \\ =10
Since |AB| = |CD|, points A, B, C, D form a parallelogram.

Match the one-to-one functions with their inverse functions.
Nady [450]
The inverse of a function is obtained by making x the subject of the formular of the function.

Given the function
f(x)= \frac{x}{8} -7
the inverse of the function is obtained as follows:
y= \frac{x}{8} -7 \\  \\ y+7=\frac{x}{8} \\  \\ x=8(y+7) \\  \\ \bold{f^{-1}(x)=8(x+7)}

Given the function
[tex[f(x)=x+7[/tex]
the inverse of the function is obtained as follows:
y=x+7 \\  \\ x=y-7 \\  \\ \bold{f^{-1}(x)=x-7}

Given the function
f(x)=1- \frac{x}{3}
the inverse of the function is obtained as follows:
y=1- \frac{x}{3} \\  \\  -\frac{x}{3} =y-1 \\  \\ x=-3(y-1) \\  \\ \bold{f^{-1}(x)=-3(x-1)}

Given the function
f(x)=20-0.25x
the inverse of the function is obtained as follows:
y=20-0.25x=20- \frac{1}{4} x \\  \\ \frac{1}{4} x=20-y \\  \\ x=4(20-y) \\  \\ \bold{f^{-1}(x)=4(20-x)}
