Answer:
y=5x+13 is the answer
Step-by-step explanation:
so you have to use the y=mx+b method
you plug in 3 for y and -2 for x
3=5(-2)+b,
multiply 5 and -2 to get -10
and it should leave you with 3=-10+b
add -10 to both sides, 10 + 3= 13 and 13 is your b (which is your y-intercept)
13=B
Ok so
t=number of text messsages
p=number of picture messages
total number is 33
t+p=33
if text is 0.18 per pic and picture is 0.45 per text
total cost is 8.3
0.18t+0.45p=8.3
times 100 both sides for ease
18t+45p=830
we now have 2 equations
t+p=33
18t+45p=830
multiply first equation by -18 and add to second equation
18t+45p=830
<span>-18t-18p=-594 +</span>
0t+27p=236
27p=236
divide both sides by 27
p=8.740740740740744
this is impossible becasue you can't send 0.740740740740744 of a message so you did a mistype somewhere
