Which system of inequalities with a solution point is represented by the graph?
Oy>2r-2 and y < -x-1: (3, 1)
Oy>2r-2 and y < r+1:(3, 1)
Oy>2r+2 and y < -x-1: (3, 1)
Oy>2x+2 and y < -x+ 1: -3, 1)

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

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
