For what values of the variables are the following expressions defined? 18/y

Step-by-step explanation:

A function is undefined when its denominator is equal to zero.

Therefore, to determine where the function is defined, we find out for what values the function is undefined and remove it.

If y=0, the function is Undefined.

Therefore, the function is defined for all values of y such that

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
