44/5 is the number as an improper fraction
1. (-4)^-6 * (-4)^7 = (-4)^(-6+7) = (-4)^1 =
B. -4
2. (3*10^6)*(8*10^-4) = (3*8)*10^(6-4) = 24*10^2 =
B. 2.4*10^3
Answer:
The answer is A. You just have to plug in.
Step-by-step explanation:
5x - y/3= 13
(2,-9) and (3,-6)
5(2) - -9/3 = 13
10 + 3 = 13
13 = 13 (true)
5(3) - -6/3= 13
15+ 2 = 13
17 = 13 (wrong)
