Answer:
A
Step-by-step explanation:
-3x²y² × y⁴x³
When multiplying, add the exponents:
-3x⁽²⁺³⁾y⁽²⁺⁴⁾
-3x⁵y⁶
Answer is A.
Answer:
-7
Step-by-step explanation:
First, we need to substitute x in as 14 since that is what x is equal to.
1. x / y => 14 / y
Next, we need to substitute y in as -2 since that is what y is equal to.
2. 14 / y => 14 / -2
Now to solve it;
3. 14 / -2 => -7
So now we now that x / y equals -7 when x = 14 and y = -2.
