Question

Here is an inequality: -2x>10

Select all the values in the list for x that would make this inequality true

-10
-4
2
-6
-5
-8
0
-43

Answer 1

-10

-6

-8

-43

Explanation:

(-2)*(-10)=20, 20>10

(-2)*(-4)=8, 8<10

(-2)*2=-2, -2<10

(-2)*(-6)=12, 12>10

(-2)*(-5)=10, 10=10, so it is not true

(-2)*(-8)=16, 16>10

(-2)*0=0, 0<10

(-2)*(-43)=86, 86>10

hope this helps :D

Answer 2

The answer is -6, -8, -10 and -43.

Explanation:

You can solve it :

-2x > 10

x < 10 ÷ -2

x < -5

(take note: you have to change symbol when it is divided by a negative no.)

Then choose the numbers from the options that satisfies the inequality, x < -5
