4a² + 6a + 1) + (4a2 + 2 – 7a)

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

1=b 2=c 16=c can i get brainliest

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
