Answer: B
Step-by-step explanation:
Answer a is incorrect because only the seniors were questioned and answer c is incorrect because nothing was mentioned in the question about only testing males.
Your answer is B
Answer:
13/2
Step-by-step explanation:
Answer: Yoko=24, Rafael=57, Jim=19
<u>Step-by-step explanation:</u>
Yoko: x + 5
Rafael: 3x
Jim: x
Yoko + Rafael + Jim = Total text messages
x + 5 + 3x + x = 100
5x + 5 = 100
5x = 95
x = 19
************
Yoko: x + 5 = (19) + 5 = 24
Rafael: 3x = 3(19) = 57
Jim: x = 19
Using the two given solutions and the general absolute value function we will get:
|x + 9| = 27
<h3>
Which absolute value function has that solution set?</h3>
The two solutions are:
x = 0 and x = -18.
Remember that the absolute value equation is something like:
|x - a| = b
If we want to have these solutions, then:
|0 - a| = b
|-18 -a| = b
From the first one, we have:
|-a| = b
Replacing that on the second equation we get:
|-18 -a| = |-a|
Notice that if we take a = -9, then we have:
|-18 + 9| = |+9|
|-9| = |+9|
This is true, so a = -9.
Then we find the value of b:
|18 + 9| = b = 27
Then the absolute value equation is:
|x + 9| = 27
