Solve: -4 < -2x < 10
Minchanka [31]
<h3>Answer:   -5 < x < 2</h3>

Explanation:

The expression -2x means -2 times x. To undo this, we divide all parts of the inequality by -2. Dividing by a negative number will flip the inequality sign. We go from "less than" to "greater than"

-4 < -2x < 10

-4/(-2) > x > 10/(-2) .... inequality signs flip

2 > x > -5

-5 < x < 2

This unknown number x is between -5 and 2. It cannot equal -5. It cannot equal 2.

Which represents a linear function? a. Y=2x b. 2x^2 c. Y=1/x
Kobotan [32]

Answer:

Step-by-step explanation:

Y=2x is linear (also proportional) since it involves only the first power of x

2x^2 is not linear, due to the second power of x (x^2); it is quadratic

Y = 1/x is not linear, due to x being in the denominator.
