Answer:
134 degrees
Step-by-step explanation:
Line PQS is 180 degrees. That being said, the addition of <PQR and <SQR equal 180 degrees.
Now you need to set up an equation to find out what angle PQR is. Since there is an X, you need to solve for X. The equation looks like this:
[tex](3x+5) + (x+3) = 180[/tex]
Solve for x
[tex](3x+5) + (x+3) = 180\\4x+8=180\\4x=172\\x=43[/tex]
Now plug in 43 where you see x. For this question, you only need to focus on (3x+5)
3(43) + 5 = 134
m<PQR = 134°
Do this every, single, time when you see these questions. Remember that line PQS is 180 degrees, and both of those angles are equal to 180 degrees.
If you want to check if this is true, plug in 43 into our equation we made to see if it equals 180 degrees. If it doesn't equal 180, your equation is incorrect.
3(43)+5+43+3 = 180
134 + 46 = 180
180 = 180 ✅

Write a system of equations to describe the situation below, solve, and write as an ordered pair (with number of months as x).
Two friends, Ann and Malia, are growing out their hair. They plan to cut it off at a certain point and donate it to a charity that makes wigs for people with cancer. Ann's hair is already 23 centimeters long and grows at a constant rate of 3 centimeters per month. Malia's hair is 27 centimeters and growing at a speed of 1 centimeter per month. If the girls get their hair cut on a certain day, they will have exactly the same length to donate. How long will their hair be? How long will that take?

Ann's hair length: y = 23 + 3x
Malia's hair length: y = 27 + x
Thus: 23 + 3x = 27 + x
23 + 2x = 27
2x = 4
x = 2
Ann's hair length: y = 23 + 2(3) = 29
Malia's Hair length: y = 27 + 2 = 29
Solution: (x, y) = (2, 29)
In 2 months both Ann's and Malia's hair will be 29 centimeters long.

Let's start with Ann's hair: 23 centimeters + 3 centimeters per month
Malia's hair: 27 centimeters + 1 centimeter per month
Now we can substitute the number of months for "x"
Ann's hair length = 23 + 3x
Malia's hair length = 27 +1x
We know that we want both girls to have the same hair length at the end so we can set these two equations as equal to each other:
23 + 3x = 27 + 1x Subtract 23 from both sides
3x = 4 + 1x Subtract 1x from both sides
2x = 4 Divide by 2
x=2 Now we know it will take 2 months for their hair to be the same length!
Let's plug that in to our original equations:
Ann's hair length = 23 + 3(2) = 29 centimeters
Malia's hair = 27 + 1(2) = 29 centimeters
It will take 2 months for the girls to grow their hair to the same length of 29 centimeters.
As ordered pairs, with x as the number of months, we can use the length of the girls hair as the y value.
At 0 months, Ann's hair is 23 cm and Malia's is 27 cm so the first ordered pairs are (0, 23) and (0, 27).
At 1 month, Ann's hair grows 3 cm and Malia's grows 1 cm so the second pairs are (1, 26) and (1, 28).
Finally, at 2 months Ann's hair is at 29 cm and so is Malia's so the final ordered pair is (2, 29) for both girls.
If you were to draw these equations on a graph, (2, 29) is where the lines would intersect.

5y + 30 = x
you subtract x from both sides
- x + 5y + 30 = 0

Given:
The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
To find:
All the ordered pairs that could be used to show that this claim is incorrect.
Solution:
We need to find the ordered pairs that can be replaced with (6,-10) and for which the set is not a function.
A relation is called function if there exist a unique output for each input.
If (-9,-6) is replaces with (6,-10), then the set has two outputs y=1 and y=-6 for x=-9. So, the claim is incorrect.
If (1,12) is replaces with (6,-10), then the set has two outputs y=12 and y=3 for x=1. So, the claim is incorrect.
If (-10,-10) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (4,7) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (-5,1) is replaces with (6,-10), then the set has two outputs y=1 and y=2 for x=-5. So, the claim is incorrect.
Therefore, the correct options are (a), (b) and (e).
