Explain how addition and subtraction of rational expressions is similar to and different from addition and subtraction of rational numbers.
Choose the correct answer below.
O A. When subtracting rational expressions, the resulting denominator is the ratio of the original denominators, whereas when subtracting rational numbers, the
difference is obtained by adding the negative and the resulting denominator is the LCM of the original denominators.
O B. The process of adding both rational numbers and rational expressions involves factoring the donorninators to identify the LCM of the original denominators
and then rewriting the fractions with the LCM as the denominator. The process of factoring a rational expression's polynomial denominator is similar but
more complex than the process for factoring the integer denominator of a rational number.
OC. When adding rational expressions, the rational expressions are rewritten with a common denominator and the numerators are added. However, when
adding rational numbers, the numerators are added and the denominators are multiplied.
OD. When adding rational expressions, the rational expressions are rewritten with a common denominator and the numerators are added. However, when
adding rational numbers, the numerators are added and the denominators are not changed. The resulting rational expression does not need to be simplified
whereas a rational number is always simplified until the numerator and denominator have no common

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.

step-by-step explanation:

your exact question is kind of difficult to understand, so maybe an example will explain what you're supposed to do? i'll work through the first problem on the worksheet.

suppose you have a tray of 652 brownies, and you have 5 friends that you want to feed without picking favorites. how many brownies can you dole out to each of your friends in equal amounts? how many will be left over for you to eat?

what you're doing here is finding a way to arrange the number 652 as the sum of integer multiple of 5 and some remainder:

here ("q" for quotient) is the number of brownies each of your friends get, and is the remainder. that's the basic idea behind division.

we break up the number 652 into parts so that the leading digit stands on its own:

652 = 600 + 52

first we check if it's possible to hand out exactly 100 brownies to each friend. with 5 friends, this means we want to know if we can take out 500 brownies from the tray. we can do this 1 time because we have 600 brownies to take from, and when we do that we're left with 100 + 52 brownies to divvy up. so we know that

652 = 1*500 + 152

next we want to know if it's possible to hand out exactly 10 brownies per friend. if we can, we have to remove 50 brownies from the tray each time until we can't. we have 152 brownies left, and we know that 3(50) = 150, so

152 = 3*50 + 2

now we have 2 brownies left in the tray. is it possible to hand 1 out to each of your 5 friends? no, you'd need a minimum of 5 brownies to do that. so the last 2 are yours.

putting everything together, we found that

652 = 1*500 + 3*50 + 2

and we can rearrange this to write

652 = 5*100 + 5*30 + 2

652 = 5(100 + 30) + 2

652 = 5*130 + 2

so and .

you might be more accustomed to the table depicting the algorithm. that's just a compact way of organizing what we've done above. you can consult the image i've attached below.
