How does the relationship between multiplication and division help you divide rational numbers?

To divide rational numbers, you turn the division problem into a multiplication problem by flipping the second rational number. Then you go ahead and multiply the tops and bottoms together to get your answer. If you can simplify your problem before multiplication, you can go ahead and do so to make your problem easier.

A rational number is one which can be represented using fractions. The opposite of division is multiplication and vice versa. Knowing this information, you can easily go about turning a division of two fractions into the multiplication of two fractions.
Ex.
(1/2) / (3/4) = ?
multiply the denominator of your fraction by the reciprocal of the denominator.
(1/2)*(4/3) / (3/4)*(4/3)
(4/6) / 1 = 4/6
So when dividing rational numbers, you can multiply the denominator by its reciprocal. This would be an example of converting a division problem into a multiplication one

Answer:

unbounded region

A feasible region that cannot be enclosed in a closed figure is known as an unbounded region. A feasible region is a set of all possible points of an optimization problem that satisfy the problem's constraints; feasible sets may be bounded or unbounded.

- 6x - 1

distribute parenthesis and collect like terms

- 2x - 3 - 4x + 2

= (- 2x - 4x) + (-3 + 2) = - 6x - 1

AEFI Is dilated by a scale factor of with the center of dilation at point F. Then, it is reflected over line a to create AHFG. B
Pavel [41]

Answer:

C

Step-by-step explanation:

It's stated that EFI is dilated by a scale factor of 1/3.

Dilating gives the following

FH = 1/3×FE

FG = 1/3×FI

HG = 1/3×EI

Sense ΔEFI is reflected over a line FG/FH = (1/3×FI)/(1/3×FE) = FI/FE

Notice that the following shows triangle similarity, meaning ΔEFI ~ ΔHFG.

The only answer choice that shows this would be FE/3 = FH, FI/3 = FH, and

EI/3 =HG ΔEFI ~ ΔHFG.
