Answer:

c

Step-by-step explanation:

Note that line M is the same equation as line R and hence there are infinitely many solutions.

Line R : 2x + 2y = 18

Line M : x + y = 9 ⇒ 2x + 2y = 18

Svetach [21]

Answer:

C

Step-by-step explanation:

You need to isolate the y variable. The first thing you need to do is move the 2 and 3x to the other side of the equation.

3x + 1/5y - 2 = 0

1/5y = -3x +2

Then you need to get rid of the 1/5 so you multiply both sides equation by the reciprocal of 1/5 which is 5/1 or 5.

y = ( -3x +2) 5

then you distribute the 5 to get

y = -15x+10

A cell phone company has a basic monthly plan of $40 plus $0.45 for any minutes used over 700. Before receiving his statement, J
Serga [27]

Ok so we know he used over 700 because he was charged more than 40. Then we take the $8.10 and divide 0.45 into it. This then gives you 18 more minutes. Then add 18 to 700 and you get 718 min.
