Answer:
Step-by-step explanation:
1
Given x³, we can write the equivalent expression -----------
x^(-3)
1
Given y^(-4) we can rewrite this as ----------
y^4
Here we're applying the "rule of negative exponents."
If the variables disappear and you get a statement that is never true,such as 0=5 or 4=7 then there is no solution meaning when graphed the two equations will form parallel lines which never interact
Answer:
x = -75
Step-by-step explanation:

Answer and Step-by-step explanation:
7. 70 - 180 = 110
8. 39 - 180 = 141
9. 81 - 180 = 99
10. 81 - 180 = 99
11. 115 - 180 = 65
12. 41+36 = 77 - 180 = 103
x = answer
