Question

Which graph shows the solution set for Negative 1.1 x + 6.4 greater-than negative 1.3? A number line going from negative 10 to 0. An open circle is at negative 7. Everything to the left of the circle is shaded. A number line going from negative 10 to 0. An open circle is at negative 7. Everything to the right of the circle is shaded. A number line going from 0 to 10. An open circle is at 7. Everything to the left of the circle is shaded. A number line going from 0 to 10. An open circle is at 7. Everything to the right of the circle is shaded.

Answer 1

The Correct Answer is C

Explanation:

Answer 2

A number line going from 0 to 10. An open circle is at 7. Everything to the left of the circle is shaded.

Explanation:

We have the following inequality:

-1.1x + 6.4 > -1.3

to solve it, we need to isolate x, as follows:

-1.1x > -1.3 - 6.4

-1.1x > -7.7

x < -7.7/-1.1 (notice that while dividing with a negative number, the sign changes)

x < 7
