Find x- and y-intercepts. write ordered pairs representing the points where the line crosses the axes. x+y=6

Step-by-step explanation:

x + y = 6

x-intercept is for y = 0. Substitute:

x + 0 = 6

x = 6

y-intercept is for x = 0. Substitute:

0 + y = 6

y = 6

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

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
