Are we finding x? Or are we solving the equation with x
The Power of a Power Rule. In this case, you basically multiply the two exponents together, and simplify (x^4)^9 to equal x^36
Answer:
2) 11
3) 21
4) 7
Step-by-step explanation:
2) (-6) -(-17) = 17 - 6 = 11
3) 19 - (-2) = 19 + 2 = 21
4) (-13) + 20 = 20 - 13 = 7
The answer is no. Because solution (a,b) means x=a, y=b.and we have a-b=5. And (b,a) would mean x=b and y=a but then x-y=b-a=-(a-b)=-5≠5. So the pair (b,a) is not a solution.
