Answer:

y=2/7x-4

Step-by-step explanation:

Write in Slope intercept form

y=mx+b

m = slope

b = y intercept

x = x intercept

y = (0,-4)

So,

y = 2/7x+(-4)   substitute

y = 2/7x-4

Jane’s cell phone plan is $40 each month plus $0.15 per minute for each minute over 200 minutes of call time. Janes cell phone b
san4es73 [151]

Answer:

The equation is 40+0.15m = 58.00 whose solution is m =120\:minutes.

Step-by-step explanation:

Let us call m the number of minutes the phone is used over 200 minutes, then we have

\boxed{40+0.15m = 58.00} <em>(this says monthly bill of $40 plus the cost of phone usage over 200 minutes must equal $58 )</em>

This equation can be used to solve for  m u as follows:

0.15m = 58-40

m = \dfrac{18}{0.15}

\boxed{m = 120\:minutes}

I need help with this please and thank you.
SashulF [63]

Answer: I believe the answer would be as follows:

8.431 grams

5.46 seconds

980 meters

900 miles

Step-by-step explanation:

it would first be which has the largest number after the decimal point, so if there’s three it goes first (0.12*3*). Then you would pick the one that is the smallest form of measurement, which would be meters in this case.


Hope this helped!

Two angles of a quadrilateral are of measures 75° and 117° respectively and the other two angles are equal find the measure of e
insens350 [35]

<u>Answer:</u>

<u>Step-by-step explanation:</u>

The sum of interior angles of a quadrilateral is 360°.

If we consider the measure of one of the unknown angles to be x°, we can set up the following equation:

x + x + 75^\circ + 117^\circ = 360^\circ

Now we can solve for x:

⇒ 2x + 192^\circ = 360^\circ

⇒ 2x = 360^\circ - 192^\circ        [subtracting 192° from both sides]

⇒ 2x = 168^\circ

⇒ x = \frac{168^\circ}{2}                      [dividing both sides by 2]

⇒ x = \bf84^\circ

Therefore, the other two angles each have a measure of 84°.

drek231 [11]
<h2>Answer:</h2>

Four points are always coplanar if:

A. They lie in the same plane.

C. all of them are collinear.

<h2>Step-by-step explanation:</h2>

<u>Coplanar--</u>

The points are said to be coplanar if all of them lie in the same plane.

<u>Collinear-</u>

The points are said to be collinear if all of them lie on a straight line.

Also as we know that a line always lie in one plane and so all the points that lie on that line will also lie in the same plane.

Hence, we may say that Four points will be coplanar if all of them are collinear.

      Hence, the correct options are:

         Option: A and Option: C
