Answer:

10.58

Step-by-step explanation:

Asume her electric bill was $A in june.

in July: A+18.02

in Augest: (A+18.02)+1.03

in September: ((A+18.02)+1.03)-0.44

and so on...

After 5 months it should be:

((((A+18.02)+1.03)-0.44)-6.84)-1.19 = A + 10.58

So after 5 months the total change is 10.58

Answer:

18.02+1.03=19.05

19.05-0.44=18.61

18.61-0.84=17.77

17.77-1.19=16.58

Solve the system. <br> y= -2x + 1<br><br> y= 2x - 3
Neporo4naja [7]

Equation 1: y = -2x + 1

Equation 2: y = 2x - 3

Since both equations already have y isolated, we are able to simply set the right side of both equations equal to each other. Since we know that the value of y must be the same, we can do this.

-2x + 1 = 2x - 3

1 = 4x - 3

4 = 4x

x = 1

Then, we need to plug our value of x back into either of the original two equations and solve for y. I will be plugging x back into equation 2 above.

y = 2x - 3

y = 2(1) - 3

y = 2 - 3

y = -1

Hope this helps!! :)
