Question

ALGEBRA 2 HELP PLEASE
QUESTION WILL BE IN THE DISCUSSION

Answer 1

The function p(x) = 2x +1 determines how many pizzas need to be purchased for an after school meeting, where x is the number of students at the meeting. The club leader uses r(p(x)) to find the amount of money to bring for the pizza purchase. The function r(x) = 4x − 3. Solve for how much money to bring when there are 9 students in the meeting

Answer 2

@perl

Answer 3

so you need to find r(p(9))

Answer 4

I have been on this question for 10 minutes. I honestly dont know how to work this out. can you please walk me through it

Answer 5

lets find an expression for r(p(x))

Answer 6

p(9) = 2(9) + 1 = 19
p(x)=19
r(p(9)) = r(19) = 4(19) - 3 = 73

Answer 7

Thank you @moralmer000

Answer 8

you are very welcome

Answer 9

On the graph of the equation 5x − 2y = 20, what is the value of the y-intercept?

Answer 10

@moralmer000 @perl

Answer 11

y=-5/2x-10
y= mx+b
M= slope
b= y-intercept

Answer 12

so y-intercept = -10

Answer 13
