2 + 3w < -1 < 3w + 5 |subtract 3w from all sides

2 < -1 - 3w < 5 |add 1 to all sides

3 < -3w < 6 |change the signs

-3 > 3w > -6 |divide both sides by 3

-1 > w > -2 → -2 < w < -1 → w ∈ (-2, -1)

What x values would be good to use so she does not get fractions for her y values when making the table of ordered pairs.

Ber [7]

Answer:

-3, 0, 3

Step-by-step explanation:

Given, $y = -\frac{4}{3}x + 2$ , the set of x values that will make Kayda not to get y values that are not fraction are -3, 0, 3.

This is so, because,

when x = -3, $y = -\frac{4}{3}(-3) + 2 = \frac{12}{3} + 2 = 4 + 2 = 6$

when x = 0, $y = -\frac{4}{3}(0) + 2 = -0 + 2 = 2$

when x = 3, $y = -\frac{4}{3}(3) + 2 = \frac{-12}{3} + 2 = -4 + 2 = -2$

The correct response is -3, 0, 3
