which of the following are solutions to the equation below x^2+4x-9=x+1 check all that apply a. 2 b. 4 c. -7 d. -3 e. -5 f. -4

a. and e.

Step-by-step explanation:

Hello, there are two ways to handle this kind of question.

... Either you solve the equation ...

So the right answers are a. and e.

... Or, you check which answer can be right.

We replace x by 2 and the two expressions are equal.

So this is a. 2

We replace x by 4 and the two expressions are not equal.

So this is not b. 4

We replace x by -7 and the two expressions are not equal.

So this is not c. -7

We replace x by -3 and the two expressions are not equal.

So this is not d. -3

We replace x by -5 and the two expressions are equal.

So this is e. -5

We replace x by -4 and the two expressions are not equal.

So this is not f. -4

Thank you.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
