1. Solve the system by Elimination: -10x-8y=6
10x+8y=-8

2. Solve the System of Equations by Graphing:
y=-2x+3
x-2y=4
and please add the graphing points too each and show work for each

Janie has $3. she earns $1.20 for each chore she does and can do fractions of chores. she wants to earn enough money to buy a cd for $13.50.

Factor the polynomial expression x6 – x3 – 20

Multiply and simplify. (x - 4) (x^2 – 5x – 6) i will mark brainliest if your answer is right. show how you got the answer. if your answer is correct but does not show how you got the answer you will not be marked brainliest.
