A ^ 3b ^ -2 / ab ^ -4, a ≠ 0, b ≠ 0
First we rewrite the expression respecting the properties of the exponents.
b ^ -2 = 1 / b ^ 2
1 / b ^ -4 = b ^ 4
We have then:
a ^ 3b ^ -2 / ab ^ -4
a ^ 3b ^ 4 / ab ^ 2
answer:
An expression using positive exponents is
D a^3b^4/ab^2

Answer:
A reflection of D over line l would simply look like a backwards D. Reflecting it again over the line m would make it look like it did originally, a normal D.

Answer:
The ordered pairs (-2,3) and (5,1) make the inequality true.
Step-by-step explanation:
In this case this "of" means we will multiply the two fractions "4/5 × 3/4" exists 3/5.
<h3>What are fractions?</h3>
That operation exists utilized to 'simplify' a fraction (reduce it to lower terms).
When there exists no number that goes into both the top and bottom numbers, then the fraction is in simplest form (lowest terms).
We are looking for 4/5 of 3/4. In this case this "of" means we will multiply the two fractions. To multiply fractions, we multiply
top × top and bottom × bottom
4/5 × 3/4 exists 4 × 3 on top and 5 × 4 on the bottom.
= (4 × 3)/(5 × 4)
= 12 / 20
= 3 / 5
Therefore, the correct answer is 3/5.

Answer:
a) 
b) y = 289.815
Step-by-step explanation:
We are given the following information:
The estimate regression equation for a model involving two independent variables and 10 observations follows:
where 
are the two independent variable and y is the dependent variable.
a) The regression line is of the form:
Comparing, we get,
These are the coefficients of respectively, and helps us to know the the significance of the independent variable in predicting the independent variable.
b) We have to estimate y when
