Answer:

y=2x-2

Step-by-step explanation:

slope = rise/run which is going up 8 and over 4

slope = 8/4 = 2

y intercept is -2

formula of a line y=mx+b

m is the slope  

b is the y intercept

in this case it would be

Find the measure of an angle between 0º and 360º coterminal with an angle of –110º in standard position
kondor19780726 [428]
<h2>Answer:</h2>

An angle measures how how much you have to rotate one line called <em>initial side</em> so it lies on the top of other line called the <em>terminal side. </em>Angles whose vertex is located at the origin having the initial side on the positive x-axis is said to be in standard position. On the other hand, coterminal angles are angles in standard position having the same terminal side. In this way, for the angle:

-110^{\circ} \\ \\ Its \ coterminal \ is: \\ \\ \alpha=360^{\circ}-110^{\circ}=\boxed{250^{\circ}}

Jason's business computers need servicing. The expression 81x + 108 represents a contractor's total charges in dollars for fixin
Zielflug [23.3K]

Answer:

The Jason's company charges more than the contractor's company.

Step-by-step explanation:

There are two expressions given for total charges for two companies as 81 x+108 and 103 x+64.

Here x represents number of hours.

We are asked to find difference in total charges if that takes 45 minutes.

45 minutes = \frac{3}{4} hours.

Plug in this value for x.

81x+108 =81*\frac{3}{4} +108

Simplify it

60.75 +108 =168.75

Now, for 103x+64 =103 *\frac{3}{4} +64

Simplify it,

77.25+64=141.25

If we see the total charge for both companies for 45 minutes, the Jason's business computers charges more than contractor's company.
