Answer:

Domain = All real numbers

Range = y ≥ 0

Step-by-step explanation:

As for the domain... you can substitute any value for x and get a mathematical response. Therefore... the domain is all real numbers

Because we are finding the absolute value of the entire function... we know that the final answer cannot be negative. (Don't forget that it <em>can</em> still be 0) Since y can only be positive... we define the Range as y ≥ 0

(-5,2) (-5,-1) how to find the slope-intercert form

Novay_Z [31]

The slope-intercept form of (-5,2) (-5,-1) is undefined

<u>Solution:</u>

Need to find the slope intercept form of line passing through two point (-5,2) (-5,-1).

Slope intercept form of line passing through $\left(x_{1}, y_{1}\right) \text { and }\left(x_{2}, y_{2}\right)$ is given by

$y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\left(x-x_{1}\right)$

$\text { Here in this problem } \mathrm{x}_{1}=-5, \mathrm{x}_{2}=-5, \mathrm{y}_{1}=2 \text { and } \mathrm{y}_{2}=-1$

On Substituting the values we get the slope intercept form of given points,

$\begin{array}{l}{y-2=\frac{-3}{0}(x+5)} \\\\ {y-2=-\frac{3(x+5)}{0}}\end{array}$

= undefined

Hence the slope intercept form of given points is undefined

jon used a gift card to pay for an $18 shirt.The remaining balance on the card is $28.write and solve an equation that represent

denis-greek [22]

Take note that they spent $18 afterwards having $28 on the card so they're spending money off the card so...

x-18=28

would be the equation for this and to solve do the following.

First add 18 to both sides making the equation.

x=46

Solve for x. The triangles in each pair are similar please question number 14

Brilliant_brown [7]

Given that the triangle CDE is similar to triangle CML, it means that the ratio of their corresponding sides are equal. It means that

CD/CM = DE/ML = CE/CL

CD = 20 + 12x + 2 = 12x + 22

CE = 30 + 12 = 42

20/12x + 22 = 12/42

By cross multipying, it becomes

12(12x + 22) = 20 * 42

144x + 264 = 840

144x = 840 - 264 = 576

x = 576/144

x = 4
