Select the inequality that corresponds to the following graph:
a. 4x+3y≥12
b. 3x+4y< 12
c. 3x-4y< 12
d. 4x+3y≤12

d. 4x+3y≤12

Step-by-step explanation:

To solve the problem we need to find the equation of the red line, since it is part of the inequality.

This should be like the following y=mx+b, where 'm' is the slope.

The slope can be obtained using the following equation:

If we use the points given by the graph (0,4) and (3,0) we will obtain that m=-4/3

Now, to find 'b' we just need to evaluate any point ine equation y=mx+b. iike (0,4).

4=-4/3*0 + b.

b=4

Our line has the following equation: y= -(4/3)*x +4, that can be written in standard form as 3y+4x=12

The region is below the graph, hence our inequality shoul be 3y+4x<=12.

The iqual sign part comes watching the graph, the line is drawn using solid line, hence the line is included in the region.

its c or d   take a lucky guess my dude

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
