We have two rational expressions. One in numerator and one in denominator.
Dividing by a fraction is equivalent to multiplying by its reciprocal. The rational expression in the denominator can be multiplied by taking its reciprocal to simplify the overall expression as shown below.

There are no common factors, so the expression can be simplified any further.
Answer:
7. Positive association
8. No association
Step-by-step explanation:
7. In this scatterplot, the points form a rough line that goes higher as the x values increase. In other words, it's tilting up, and its slope is positive. This signifies a positive association or correlation.
8. In this scatterplot, there seems to be no particular pattern; the points are random. Notice how there is no rough line or shape formed by these points. Since there is no relationship between "Salary" and "Height," there is no association or correlation.
Answer:
15
Step-by-step explanation:
Given that a1 = 6
an = 3 + 2(an-1),
Substitute n = 2 into the formula
a2 = 3 + 2(a1)
a2 = 3 + 2(6)
a2 = 3+12
a2 = 15
Hence the second term of the sequence is 15
Answer:
-1y+1x-2
Step-by-step explanation:
if you are combining like terms this is how you do it at all of the same variables together to simplify the expression
