The scale factor of the dilation is 1/5
in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our
so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases
y intercept is 5
slope is 2
pls mark as brainliest
hello from mrbilldoesmath!
25x^2 + 90x + 84
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!
