What is the slope of the line?
answer choices:
a.1
b.3
c.1/3
d.-3

B

Step-by-step explanation:

You could plug in the point given with another point but for simplicity, you can count how far away you are from the vertex. (Since the y intercept is at 0,0)

Go up 3 spots from the vertex, and then go one spot to the right. Ay now you're at (1,3)

You went up 3 and right 1, which translates to simply 3

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

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
