Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers cost $0.05 each. How much would Mrs. Algebra’s single order be? Use the expression below to calculate the total.

13.63

Step-by-step explanation:

I. E 12.99 +0.49 +0.10 +0.05

=13.48+0.10+0.05

=13.58+0.05

=13.63 dollars

I. E Mrs. Algebra's single order will be 13.63 dollars

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

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
