Answer:
Step-by-step explanation:
y = 25x +100
y- is the total money spent on the phone
x-is the number of months you had service
the relationship between x and y is proportional ( if x grows, y grows)
For example: after 2 months you would had payed $100 for the phone + the $25 each of the 2 months. y= 25*2 +100 = $150
Approximately 7 people.
Make a proportion of x/6 and divide 40 by 6. We get 6.23333...
This is approximately 7 people.
32
Step 1: Multiply Both sides by 4: result is 96 = 3r
Step 2: Divide both sides by 3: result is 32 = r
and there is your answer!
I hope this helped, and please mark this as brainliest!
let b =x^2
b^2+10b+25
b^2+5b+5b+25
b(b+5)+5(b+5)
(b+5)^2
therefore
(x^2+5)^2
