There are 10 desks, 12 chairs and 4 cabinets. What's the ratio of chairs to all
items?

Step-by-step explanation:

By simply adding all of the items, you end up with 10 + 12 + 4, or 26 items.  Then, simply set the number of chairs to the number of total items, or 12 : 26.  This ratio can also be expressed as the fraction 12/26, and can be simplified into 6/13, or 6 : 13, by dividing both the numerator and denominator by 2.

Hope it helps :) and let me know if you want me to elaborate.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
