22.90*1.05=24.045
sales tax is 5% added to 100% of the original cost making the actaul cost including tax $24.045
List the hours from 1 to 8
Multiply the hours by how much she is paid per hour ( $12)
X: 1, 2, 3, 4, 5, 6, 7, 8
y: 12, 24, 36, 48, 60, 72, 84, 96
The lines y = 2x - 1 and y = -2x + 3 intersect at exactly one point which means this system has exactly one solution. so the system is consistent and independent
Answer:
4x^2-81y^2 is NOT a perfect square trinomial, factored. You know this because if you factor this to (2x+9y)(2x-9y) then you will see that the signs between terms in the parenthesis are DIFFERENT.
Step-by-step explanation:
Taking notes as you go through the course will help you retain and process the information much better than getting "help" from a site that is probably badly named.
