Melissa bought 3 loaves of freshly baked bread at a specialty bread shop. she paid twice as much for the whole grain bread as for the french bread, and $2.50 more for the cinnamon raisin bread than for the whole grain bread. she spent a total of $11.25 for the 3 loaves. if f represents the price of a loaf of french bread, which equations describe this situation? select two answers.
a. f +f (f + 2.50) = 11.25
b. f + 2f+(f + 2.50)= 11.25
c. f + 2f + (2f + 2.50) = 11.25
d. 2f + 2.50 = 11.25
e. 5f = 8.75

207/8 is the right

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!

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
