<u>Length</u><u> </u><u>is</u><u> </u><u>6</u><u>√</u><u>2</u><u> </u><u>units</u><u> </u><u>or</u><u> </u><u>8</u><u>.</u><u>4</u><u>9</u><u> </u><u>units</u>

Step-by-step explanation:

Length formular:

$length = \sqrt{ {(x _{2} - x_{1}) }^{2} + {(y_{2} - y_{1})}^{2} }$

x1 is 2

x2 is -4

y1 is 3

y2 is 9

$length = \sqrt{ {( - 4 - 2)}^{2} + {(9 - 3)}^{2} } \\ \\ = \sqrt{ {( - 6)}^{2} + {6}^{2} } \\ \\ = \sqrt{36 + 36} \\ = \sqrt{2 \times 36} \\ = \sqrt{2} \times \sqrt{36} \\ { \boxed{ \boxed{= 6 \sqrt{2} }}} \\ = 8.49 \: units$

Write an algebraic expression to represent the pay (in dollars) for working "x" hours at a rate of eight dollars and seventy-fiv

Olenka [21]

Step-by-step explanation:

Hours worked = X

Money earned per hour = $8.75

Your answer would be A.

E.g.) Say that there is another part to this question.

You work for 3 hours, how much money would you earn after three hours? Use your equation "8.75x"

We know that "x" is equal to the hours worked, so plug in 3 for x.

8.75x = 8.75 *x

8.75 * 3= 26.25

So, if you worked 3 hours, your total pay would be $26.25 (Note: this is not part of your answer, just an example to show you how equations work)

Hope this helps :)
