Answer:
3•10^3 is 3,000, so the answer is 9,000
Answer:
I think the answer is 1
Step-by-step explanation:
-49÷7=-7
-7÷-7=1
Answer:
D
Step-by-step explanation:
10/7 = 1.4285
9/y = 1.4285
Multiply both sides by y.
9 = 1.4285y
Divide both sides by y.
6.3 = y
So discriminant is being counted from that equation:
b^2-4ac = 36-36 = 0
As discriminant is 0, then there is just 1 root -> -b/2a = 6/2 = 3.
The answer is C. You shouldnt cheat and actually learn though it will help you in the future.
