Question

Select the inequality that corresponds to the given graph.



5x + 7 ≥2 and 10x ≤30

6x + 7 ≥ 25 or 2x - 8 < -4

4x + 10 ≤ 6 or 5x - 6 ≥ 14

37 ≤ 8x - 3 ≤ 61

Answer 1

where is the graph ?

Answer 2

@AravindG theres the graph

Answer 3

Okay, we've got two filled-in circles, so our answer must have <= or >= in both inequalities. That eliminates the 2nd choice. Now look at the others and try some points. I like to use 0 as a test point, because the arithmetic is easy. Looking at the last choice,

\(37 \le 8x -3 \le 61\)

if we plug in 0, does it satisfy it?

\(37 <= 8(0) -3) \le 61\)

is false, so that can't be our answer. Repeat for the rest of the choices, until you find one that works.

Answer 4

Nuts, that should be
\[37 \le 8(0)-3 \le 61\]
