Consider the solution to the system of inequalities below.
ſy s0.5x+2
Ly> 3x-3
Which of the following functions could be added to the system without changing the solution set?
o y> 2
o y<3
o y<2
o y=3

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

part a: 1.08

part b: 27.59

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

you,

i can answer this if i have the answer choices
