PLZ help!!

Paladinen [302]

Answer:

Step-by-step explanation:

At the self employed store, her monthly expense would be

y = $835

Which would plot as a horizontal line

At the franchise store here expense would be

y = 5x where x is the number of haircuts completed.

This would plot as a straight line of slope 5

The two would intersect when the two y values are equal

5 x = 835

so the same cost per month would occur at y = 835

at the franchise, she would have completed 835/5 = 167 haircuts.

If she plans on doing fewer than 167 haircuts per month, she nets more money at the franchise,

If she completes more than 167 haircuts per month, the self employed store deal keeps more money in her pocket.

Solve the following equation<br>1) 2c + c + 12 = 78

Annette [7]

Step-by-step explanation:

(2c+c) + 12 =78

3c + 12 = 78

78 - 12 = 66

66 ÷ 3 = 22

22 + 22 + 22 + 12 = 78

{ C = 22 }

Use slopes and y-intercepts to determine if the lines 10x+3y=−3 and 5x−4y=−3 are parallel.

kvasek [131]

Answer:

They are not parallel

Step-by-step explanation:

original equation

10x + 3y = -3

subtract 10x

3y = -10x - 3

divide by 3

y = -10/3x - 1

original equation

5x - 4y = -3

subtract 5x

-4y = -5x-3

divide by -4

y = 5/4x + 3/4

the slopes are not equal to each other (5/4x and -10/3x) so they are not parallel

Part 1: The equation of the line is $y=2x+1$

Part 2: The equation of the line in slope intercept form is $y=-3x-1$

Explanation:

Part 1: It is given that the point A is $(1,3)$ and the line B is $y=2 x-2$

To determine the line passing through the point A and parallel to line B, let us first determine the slope and y-intercept.

From the equation of line B, the slope is $m=2$

Substituting the point $(1,3)$ and $m=2$ in slope intercept form $y=mx+b$ , we have,

$3=2(1)+b$

$3=2+b$

$1=b$

Thus, the y-intercept is $b=1$

Let us substitute the values $m=2$ and $b=1$ in the slope intercept form $y=mx+b$ , we get,

$y=2x+1$

Thus, the equation of the line passing though point A and parallel to line B is $y=2x+1$

Part 2: The given two coordinates are $(-1,2)$ and $(1,-4)$

To determine the equation of line in slope intercept form, first we shall find the slope and y-intercept.

From the graph, we can see that the line touches the y-axis at -1.

Hence, the y-intercept is $b=-1$

The formula for slope is $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substituting the coordinates $(-1,2)$ and $(1,-4)$ , we have,

$m=\frac{-4-2}{1+1} =\frac{-6}{2} =-3$

Thus, the slope is $m=-3$

Substituting the values $b=-1$ and $m=-3$ in the slope intercept formula $y=mx+b$ , we get,

$y=-3x-1$

Thus, the equation of the line in slope intercept form is $y=-3x-1$
