Answer:
3/2
Step-by-step explanation:
to get 3/2 you would flip the fraction and change it's sign to get it's negative reciprocal or "opposite"
Hey there!
For this problem, I believe that they're saying that a number divided by –2/3 is equal to –9/10.
We can tell immediately that the mystery number is a positive number, since two negative numbers being divided by one another will give you a positive quotient.
For actually solving the problem, you can refer to what you learned (presumably) a while ago about number families:
9 / 3 = 3
3 * 3 = 9
Using that, you can assume the following will get you your mystery number:
x / –2/3 = –9/10
–9/10 * –2/3 = x
For multiplying fractions, all you need to do is multiply the numerators and the denominators together. The denominator doesn't have to be the same on both fractions.
(–9/10) * (–2/3) = 18/30 = 9/15
To check, all you have to do is remember the original problem:
(9/15) / (–2/3) =
(9/15) * (–3/2) = –27/30 = –9/10
When multiplying fractions, remember that the negative applies to both the denominator and numerator. Also, when dividing fractions, you will multiply the (untouched) first fraction by the second fraction with the numerator and denominator, aka the reciprocal.
Hope this helped you out! :-)
I’m not sure if it’s right but I got (x+1)(x+2)(x+3) as an answer.
Explanation: factor by grouping (x+1)(x^2+5x+6)
Find one factor use factor by grouping and that’s how I got the answer (x+1)(x^2)(x+3) I hope this helps you

This relation is a function because a function, in fact this is a linear function. We have that:
![\left[\begin{array}{cc}x & y\\2 & 3\\4 & 4\\6 & 5\\8 & 6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Dx%20%26%20y%5C%5C2%20%26%203%5C%5C4%20%26%204%5C%5C6%20%26%205%5C%5C8%20%26%206%5Cend%7Barray%7D%5Cright%5D)
As you can see below, all the points have been plotted an this is a linear function. Therefore, with two points we can get the equation, so:
Finally, the equation is:
4 1/4 = 17/4
17/4 • 5 = (17•5)/4
17•5 = 85
85/4 = 21 1/4
