Answer:
1 + 2x = f(x) i believe
Step-by-step explanation:
Answer:
[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 2x + 1 ( subtract 1 from both sides )
y - 1 = 2x ( divide both sides by 2 )
[tex]\frac{y-1}{2}[/tex] = x
Change y back into terms of x
[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Whitney made 7 1/2 quarts of hot chocolate. Each mug holds 5/6 of a quart. How many mugs
will Whitney be able to fill?
Write your answer as a fraction or as a whole or mixed number.
Answer:
15
Step-by-step explanation:
The total of hot choclate made by Whitney = 7 1/2 quarts.
= 7 (2) + 1 15
----------- = ---
2 2
each mug holds 1/2 quarts
Total quarts of the hot chocolate ÷ quarts of hot choclate hold by each mug:

= 15
Whitney will be able to fill 15 mugs
Camden is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 5 points. What would be Camden's test score out of 50 if he got 2 questions wrong? What would be his score if he got x questions wrong
Answer:
Step-by-step explanation:
Score of 2 questions = 2 *5 = 10
He got 2 questions wrong. So, 50 - 10 = 40.
Camden's test score out of 50 = [tex]\frac{40}{50}[/tex]
Score for x questions = x *5 = 5x
Camden's score if he got 'x' questions wrong = 50 - 5x

A president and vice-president for a student organization are chosen from eleven people. How many different president/vice-president combinations are possible?
Answer:
110 combinations.
Step-by-step explanation:
We are going to be choosing without replacement.
Out of 11 people, we can choose one president, but after choosing, we would be left out with 10 people to choose a vice president from.
To calculate the possible combinations of president and vice-president, we multiply 11 by 10
11 x 10
= 110
Therefore we have 110 vice-president/president possible combinations.

1/4a + 1/3a + 8 = 22 what would be the steps to solve this
Answer:
Step-by-step explanation:
first i would combine like terms so 1/4a + 1/3a is equal to 7/12 then the equation would be 7/12a+8=22 simplify the isolate the variable so i think it A=24
Answer:
Hey there!
Step-by-step explanation:
Equation: 1/4a + 1/a + 8 = 22
(The answer is 24)
(You have to do 3 steps in order to solve this question! The steps are below!)
~1. First you have to simplify both sides of the equation.
=> (1/4a + 1/3a) + (8) = 22
=> 7/12a + 8 = 22
~2. Next, subtract 8 from both of the sides.
After you do that you will get, 14
7/12a=14
~3. Lastly, you just multiply both sides by 12/7.
(12/7) x (7/12a)
(12/7) x (14)
~Therefore, A would equal to 24.
A=24
~Hope this helps!
~Good luck! :)

Corinne has a job selling magazines. She earns $7.50 per hour plus 20% of the total amount of her sales. She also gets an allowance of $40 per week for gas. She knows her weekly earnings can be shown using the following expression: 7.50h + 0.20s + 40 Part A: Identify a coefficient, a variable, and a constant in this expression. (3 points) Part B: If Corinne works for 25 hours and sells $300 in magazines, how much does she earn for the week? Show your work to receive full credit. (4 points) Part C: If Corinne gets a raise and begins earning $9 per hour, would the coefficient, variable, or constant in the equation change? Why?
Part A
The coefficient would be the number that is with a variable. The coefficient of 7.50h is 7.50. The variable is h, variables can be a letter or symbol that stands for something in a equation. For this question, h stands for the number of hours Corinne works. The constant is the number that is alone in the equation. That doesn't have a variable with it. In this equation the constant would be the number 40.
Part B
To solve this I will plug in 25 into "h" in and 300 for "s" in the equation 7.50h + 0.20s + 40 and then solve it.
25 × 7.50 = $187.5.
0.20 × 300 = $60
Total: $187.50 + $60 = $247.50 + $40 = $287.50
Part C
If Corrine gets a raise and earns $9 an hour the coefficient would change. It would be 9h instead of 7.50h.

Stacy sent 10 more texts than twice her little sister yesterday together they sent 46 texts how many texts did Tracy send
Answer:
Tracy sent 12 texts
Step-by-step explanation:
hope this helps
Answer:
The answer is 12 texts.
Step-by-step explanation:
Ok, so I'm assuming that Tracy is the little sister.
Stacy's texts: s
Tracy's texts: t
46 = s + t
s = 2t + 10
Substitute 2t + 10 for s in the first equation.
46 = 2t + 10 + t
46 = 3t + 10
-10 -10
36 = 3t
36/3 = 12
Tracy sent 12 texts and Stacy sent 34 texts.

Complete the table for the graph of the equation x + 2y = -1
x f(x)
-2?
0?
3?
[tex]x + 2y = -1\\x=-2,0,3\\f(x)=y\\[/tex]
plug in each value of x in the function y:
[tex]-2+2y=-1\\2y=1\\y=\frac{1}{2}[/tex]
first point is [tex](-2, \frac{1}{2})[/tex]
so when x = -2, f(x) = 1/2
[tex]0+2y=-1\\2y=-1\\y=-\frac{1}{2}[/tex]
second point is [tex](0,-\frac{1}{2})[/tex]
so when x = 0, f(x) = -1/2
[tex]3+2y=-1\\2y=-4\\y=-2[/tex]
third point is [tex](3,-2)[/tex]
so when x = 3, f(x) = -2

Identify the inequality for the given graph.
Answer:
We. can see there's a black point at -3.7 and an arrow going to the left.
As the arrow goes to the left, it must be less than -3.7 or less than or equal to -3.7, now, we will need to see the colour of the point to know which it is.
As there is a black point, -3.7 is also contained in this range...
What does that mean? That means it will be less than or equal to -3.7
So we know the correct option is a) less than or equal to -3.7, what we could write as ([tex]-\infty,-3.7[/tex]].
