Type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar(s).

first box is x+3

second box is 5

Step-by-step explanation:

To find the first f(x) equation , lets pick two points from the slanting line

(-3,0)(-2,1)

lets find the equation of this line

we need find equation y=mx +b

m=1  and point is (-3,0)

use formula y-y1=m(x-x1)

y-0 = 1(x-(-3))

y= 1(x+3)

y= x+3

another line is a horizontal line

for horizontal line , slope is always 0

we have line at 5 on y so equation is y=5

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

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

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
