What is the slope of the line that contains the point (13,-2) and (3,-2)
ra1l [238]

The slope of the line that contains the point (13,-2) and (3,-2) is 0

<em><u>Solution:</u></em>

Given that we have to find the slope of the line

The line contains the point (13,-2) and (3,-2)

<em><u>The slope of line is given as:</u></em>

m = \frac{y_2-y_1}{x_2-x_1}

Where, "m" is the slope of line

Here given points are (13,-2) and (3,-2)

(x_1, y_1) = (13, -2)\\\\(x_2, y_2) = (3, -2)

<em><u>Substituting the values in formula, we get,</u></em>

m = \frac{-2-(-2)}{3-13}\\\\m = \frac{-2+2}{3-13}\\\\m = 0

Thus the slope of line is 0

A roof repairman charges a $60 consult fee, and then $45 per hour to complete repairs. if the homeowner pays a total of $195, ho
Thepotemich [5.8K]

The time spent by the repairman there will be 3 hours so the correct answer is option D.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that:-

A roof repairman charges a $60 consult fee, and then $45 per hour to complete repairs. if the homeowner pays a total of $195.

The time will be calculated as:-

Total amount =  $195

Now the fixed consulting cost will be $60 and will be deducted from the

total amount.

Variable cost = 195 - 60 = 135

The $45 per hour charge so for $145 the time will be:-

Time = 135 / 45

Time =  3 Hours

Therefore the time spent by the repairman there will be 3 hours so the correct answer is option D.

Solve the equation -7(2m-6) + 21=-77
Svetllana [295]

Answer:

m=10

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−7(2m−6)+21=−77

(−7)(2m)+(−7)(−6)+21=−77(Distribute)

−14m+42+21=−77

(−14m)+(42+21)=−77(Combine Like Terms)

−14m+63=−77

−14m+63=−77

Step 2: Subtract 63 from both sides.

−14m+63−63=−77−63

−14m=−140

Step 3: Divide both sides by -14.

-14m/-14=-140/-14

m=10
