I need help with this question, one cell phone plan is costs 29.94 per month plus 0.10 for each text message sent, Another plan costs 65.98 per two months plus 0.05 for each text message sent. For what number of text messages will the monthly bill for both plans be the same?

61 text messages

Step-by-step explanation:

Plan A:

29.94 + 0.10m

Plan B:

65.98 per two months

Per month = 65.98 / 2

= 32.99

32.99 + 0.05m

Where, m = number of text messages

Equate both expressions

29.94 + 0.10m = 32.99 + 0.05m

29.94 - 32.99 = 0.05m - 0.10m

-3.05 = -0.05m

Divide both sides by -0.05

m = -3.05 / -0.05

= 61

m = 61 text messages

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
