Answer: y=3x+8

Step-by-step explanation:

(1 11) and (-2 2)

Find slope first "m"

M= y2-y1/x2-x1

M= 2-11/-2-1

M= -9/-3

M=3

Now use one the points with slope to find b

Y=mx +b with point (1,11) and slope 3.

Y=mx+b

11=3(1)+b

11=3+b

11-3=b

8=b

Now substitute to make equation

Y=3x+8

Step-by-step explanation:

8/9(54x - 36) +2=-3/4(-40+ 16x) + 90x

or,432x-288+18/2 =120-48x+360x/4

or,4(42x-288+18)=2(120-48x+360x)

or,168x-1080=240-624x

or,162x+624x=1080+240

or,792x=1320

or,X=1320/792

or,X=5/3

Licemer1 [7]

Answer:

the cost of the plan in the case when 388MB is used is $101.64

Step-by-step explanation:

The computation of the cost of the plan in the case when 388MB is used

Given that

One time fee is $35

And, it involves 150 MB of data usage

Also for the extra megabyte it charges $0.28

So for 388MB, the cost of the plan is

= $35 + 0.28 × (388 MB - 150 MB)

= $35 + $66.64

= $101.64

Hence, the cost of the plan in the case when 388MB is used is $101.64
