For f(x) = -x + 8, which statement is true?
Group of answer choices
f(x + k) = f(x) + k
f(x + k) = f(x) + f(k)
f(x - k) = f(x) - k
f(x - k) = f(x) + k
I think it’s f(x+k) = f(x) + k correct if I’m wrong
(5x + 2) 6x
Solve for x and y
X =
y =
Answer:
x = 8
y = 138

Jeremy wrote this equivalent equation to solve for x:
x = negative 11 y minus 140
Which of these equations might have been Jeremy’s original equation? Check all that apply.
y + 7x = 23
y + 11x = 140
2x – 22y = –140
3x + 33y = –420
x + 140 = –11y
Answer:
3x + 33y= -420 and x + 140 = -11y

Given that Jocelyn saved $60 in 8 weeks, predict the number of weeks it will take Jocelyn to save $90. Include in your explanation any assumptions that must be made in order to make the prediction. Enter your explanation in the space provided.
number of weeks: w is the x value, and the number of money saved: m is the y value. First, we need to find out how much she makes in 1 w and because k = y/x, we need to divide 60 by 8, which gives u 7.5, so she saves $7.50 every week Finally, we figure out the number of weeks it takes her to save $90, and to do that, we use the formula x = y/k. Using that formula, we get the expression $90/$7.50 or $90/$7.5. 90/7.50 = 12, so x = 12. It will take her 12 weeks to save $90. In order to check our answer, we can say that we didn't know the number of m she saved, but we do know how many weeks. To find a solution, we use the formula y = kx (the blank between kx means that we are multiplying). Using that formula, we get the equation 12 X 7.50. When we solve this equation, we get 90, and since it is the same answer as the real problem, that means the answer for the real problem is correct. (BTW sorry this is so long)

A track team contains sprinters numbered 1,2,3,4,5 and distance runners numbered 1,2. Let S be the event of selecting a sprinter, D the event of selecting a distance runner, E the event of selecting an even numbered runner, and the event of selecting an odd runner. Selecting the sprinter numbered 1 is one outcome of which of the following events? Select all correct answers. Select all that apply: O DANDO ODORE DORO 00 OE' OS AND E
Answer:
D or O
E'
Step-by-step explanation:
Because the runner is a sprinter and the number is odd, the runner is an example of S and O. Therefore, it is also an example of E′ (not even) and D OR O.
For sprinter numbered 1 is outcome of S, D and O events.
Events to be determine that contain sprinter number 1. We have number of events that is for sprinter, distance runner, odd numbered, even numbered as S,D,O and E respectively.
Sample space = (1, 2, 3, 4, 5).
Probability can be defined as the possibility of the desired event to be happened.
Here, Numbered 1 is odd number, a sprinter and also a distance runner.
So, Numbered 1 is contain in S, D and O.
Thus, for sprinter numbered 1 is outcome of S, D and O events.

Use trigonometry to resolve the following vectors into components. Describe the vectors

In 1986 a family member invested$ 100 each month into savings account with an interest rate of 0.25% that didn't change. In 2016 you decided you needed to use that saved up money for a big purchase so you cash the savings account out
Complete question is;
In 1986, a family member invested $100 each month into a savings account with an interest rate of 0.25% (that didn't change). In 2016, you decided you needed to use that saved up money for a big purchase, so you cash the savings account out.
How much money should be in the account using the FV formula?
Answer:
FV = $107.78
Step-by-step explanation:
We are given;
Present value; PV = 100
Interest rate; r = 0.25% = 0.0025
We are told the PV was in 1986 and In 2016 you decided you needed to use that saved up money .
This is a period of 30 years.
Thus, the number of compounding periods is n = 30
Formula for FV is;
FV = PV(1 + r)ⁿ
FV = 100(1 + 0.0025)^(30)
FV = $107.78
the spinner has three regions 5 0 and 20to play the game you spin one time and then you win the amount in the region that the spinner lands on. what is the expected valuse of the game
Answer:
Step-by-step explanation:
Each region is equally likely.
5 * 1/3 = 5/3 = 1 2/3 = 1.67
0 * 1/3 = 0
20*1/3 = 6 2/3 = 6.67
Total = 8.34
So if this really were a game you should be willing to put up 8.34 to play it.
You can create a simulation. Let the computer play 10000 times (which will take seconds). I'm going to try this for you. and see what happens.
You throw 0 3309 times
You throw 5 3394 times
You throw 20 3290 times
The net result is that you will win 2.71 as you pay, which is what it should be.

Answer:
m = -7/4
Step-by-step explanation:
-2m - 6 = 6m + 8
Add -6 to both sides.
-2m = 6m + 14
Subtract 6m from both sides
-8m = 14
Now divide -8 from 14

What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that a quadratic function given the roots (4,0) and (2, 0). The quadratic equation will be formed as below:-
The two roots of the quadratic equation are 2 and 4 then the two factors will be ( x- 2 ) and ( x - 4).
y = -4(x-2)(x-4)
y = -4x² + 24x - 32.
Therefore, the expression for the quadratic function will be y = -4x² + 24x - 32.
