Answer:

You have not added the options, therefore, I cannot provide an exact answer. However, I can help you with the concept.

In any fraction, the denominator cannot be equal to zero because this would make the fraction undefined.

Excluded values are the values that would make the denominator equal to zero.

We are given that the excluded values are 2 and 5, this means that the factors of the denominator are (x-2) and (x-5)

This means that the denominator is x² - 7x + 10

Pick the fraction which has this denominator.

Hope this helps :)

Suppose you bought a pizza for $8.00. You also bought a salad but you can not remember how much you paid and you can not find th
Darina [25.2K]
The best equation would be A.

with A you get to calculate what is the value of $. 

8 + $ = 10 (10 is the total value of your receipt and 8 is the price of pizza)
$ = 10 - 8 (we transfer the price of pizza on the other side to the total amount of your receipt and calculate the remaining amount)
$ = 2

We see that the remaining amount is 2$, which means the salad cost s2$ :)

Find the measure of the missing angles.
Alenkinab [10]

Answer:

d = 69°, e = 32°, f = 79°

Step-by-step explanation:

the 69° angle and d are vertical angles, so d is 69°.

same with e and the 32° angle, so e is 32°.

the 69° angle and f are on a straight angle, which means they, and e, add up to 180° when combined.

69 + 32 = 101

180 - 101 = 79

so f is 79°.

K (3x - 2) = 4 - 6x<br> Find the value of k
svlad2 [7]

Hello!

In this case, you are looking for a value of K so the left side of the equation is equal to the right.

The left side of the equation is K (3x - 2), and the right is 4 - 6x. To get the left side to equal the right, you can set K = -2. This is because of the <u>distributive property</u>: a number just outside of the parenthesis can distribute to everything in the parenthesis like so:

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

Therefore, your answer is K = -2.

Hope this helps!

(Side note: a better way to do this would be to divide both sides by 3x - 2)
