You are selling concessions at a local swim meet. hot dogs are being sold for $1.00 and soda is being sold for $0.50. at the end of the day you made $150. let x represent the number of hotdogs sold and y represent the number of sodas sold. write an equation that can be used to find the number of hotdogs and sodas sold at the swim team.
a) standard form:
b) slope-intercept form:
c) if you sold 40 hot dogs how many sodas did you sell?
d) using the standard form, identify the x-intercept of the graph and explain how the x-intercept relates to the number of hot dogs and sodas sold.
e) using standard form, identify the y-intercept of the graph and explain how the y-intercept relates to the number of hot dogs and sodas sold.

use this equation: 150=1x+0.5y

Step-by-step explanation:

a) standard form equation above

b) 150=1x+0.5y

subtract 1x from both sides

then divide all by 0.5 to get slope intercept form

c) plug it in: 150=1(40)+0.5y and solve to get 220

d) take the y intercept from answer b. and the y intercept shows how many you have to sell of each to reach you $150(I think, this part might be wrong...idk)

i dont know

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
