Answer: 200 messages

========================================================

Check out brainly.com/question/11754609 for a similar problem

Plan A's cost equation is y = 0.10x + 30

Plan B's cost equation is y = 50

Equate the two right hand sides, then solve for x

0.10x + 30 = 50

0.10x = 50-30

0.10x = 20

x = 20/0.10

x = 200

If you send/receive 200 messages, then the two plans will both cost the same ($50) per month.

(3,4) and (0, 5)<br> write a linear equation
Nina [5.8K]

Answer:

y=-1/3x+5

Step-by-step explanation:

<u>Slope-intercept form</u>

y=mx+b

m => slope

b => y-intercept

<u>Slope</u>

m=(y2-y1)/(x2-x1)=(5-4)/(0-3)=1/(-3)=-1/3

<u>Y-intercept</u>

y=-1/3x+b

5=-1/3(0)+b

5=b

<u>Final equation</u>

y=-1/3x+5
