5x + 2y = 8
How do I solve for y
Answer:

Is (y=x^2) a function
Answer:
YES!
y=x² is a function.
Step-by-step explanation:
We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
Given the equation
y=x²
Here, for every value of x, there is a unique y-value or output.
For example,
when x = 3, y = 9, when x = 6, y = 36
In other words, it does not matter which x value of chose, there will be only output.
Therefore,
YES!
y=x² is a function.

3n -11 > 5n -18 (linear inequalities)
Answer:
n< 7/2 or n< 3.5
Step-by-step explanation:
3n -11 > 5n -18
subtract 3n on both sides:
-11 > 2n-18
Add 18 on both sides:
7 > 2n
7/2 > n
n< 7/2

Given the following sequences state the next number 1, 18, 16, 32 ____
1, 1, 2, 3, 5, 8, 13, 21 ____
-26, -15, -4, 7____
256, 225, 196, 169, ____
Answer:
Not sure about the 1st sequence
Second sequence: 34
Third sequence: 18
Fourth sequence: 144
Step-by-step explanation:
The second sequence is the Fibonacci sequence. You find the next term by adding to two previous terms, so you have 13+21 which is equal to 34.
The third sequence is an arithmetic sequence that has a common difference of 11. Knowing this, we can add 11 to the last term to find the next one. This gives us 7+11 which is 18
The third sequence is the square of numbers starting form 16 and decreasing by one each time. This can be written with the formula [tex]t_{n}[/tex]=[tex](17-n)^2[/tex], where n is the term of the sequence you are solving for. Since you need to solve for the fifth term of the sequence the equation becomes, [tex]t_{5}[/tex]=[tex](17-5)^2[/tex] which is the same as [tex]13^2[/tex], so the 5th term is 169.
x+y=5
5x - 3y - 17
answer
9514 1404 393
Answer:
(x, y) = (4, 1)
Step-by-step explanation:
We assume you want to solve ...
x +y = 55x -3y = 17Multiply the first equation by 3 and add the second:
3(x +y) +(5x -3y) = 3(5) +(17)
8x = 32 . . . . . . simplify
x = 4 . . . . . . . . .divide by 8
4 +y = 5 . . . . . . substitute into the first equation
y = 1 . . . . . . . . .subtract 4
The solution is (x, y) = (4, 1).

Jordan and Ben exercise at the same gym. The table below shows the number of calories they burned in each of their last five workouts. How many calories would Ben need to burn in his next workout to have the same average as Jordan?
Answer:
Step-by-step explanation:
Ok so find the mean of bens workout by adding 716,635,802,687,630 next divide by the number of numbers which is 5 so =3,470 divided by 5 =694 that is the mean =average now the question asks how much calories he will need to burn to average Jordan so that mean you will need to find the mean=average of Jordan by adding 850, 674 729 658 614 =3525 now divide by 5= 705 now find the difference between 705 and 694= 11 so Ben needs to burn 11 more calories to get to jordans average/ mean
Ben needs to burn in his next workout to have the same average as Jordan is 55 calories more.
What is subtraction?It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.
Jordan and Ben exercise at the same gym.
The table below shows the number of calories they burned in each of their last five workouts.
Total calories burned by Jordon in the last five days will be
Jordon's calories burn = 850 + 674 + 729 + 658 + 614 = 3525
Total calories burned by Ben in the last five days will be
Ben's calories burn = 716 + 635 + 802 + 687 + 630 = 3470
Ben needs to burn in his next workout to have the same average as Jordan will be
→ 3525 – 3470 = 55
Ben needs to burn in his next workout to have the same average as Jordan is 55 calories more.

Which expression is equivalent to 17x − 8x + 2 and why?
A. 2 − 9x, because (17x − 8x) + 2 = −9x + 2 = 2 − 9x
B. 2 + 9x, because (17x − 8x) + 2 = 9x + 2 = 2 + 9x
C. 11x, because 17x − 8x + 2 = 9x + 2 = 11x
D. 7x, because 17x − 8x + 2 = 17x − 10x = 7x
Answer:
17x − 8x + 2 = 9x + 2 ...............combine like terms

It’s a hot summer day. Darius is babysitting and has promised his sweet little sister that he will fill her wading pool. He plans to soak his feet in the water as he sips a cool soda and watch little sister as she plays in the water. Sounds great, right? All he needs to do is get the pool filled. Unfortunately, little sister is impatient and starting to whine. Darius has a hose ready in the backyard to fill the pool, but he decides he will also drag the hose from the front-yard, so the two hoses can work together to fill the pool faster. Nobody wants their darling little sister to be unhappy!
Darius knows from experience that if he only uses one hose at a time, the front-yard hose takes 10 minutes longer to the fill the pool than the back-yard hose. With the two hoses working together, the pool is filled in 12 minutes. Once Darius is comfortable with his toes dangling in the water, he starts to wonder how long it would have taken to fill the pool if he had only used one of the hoses.
Darius thinks, “Hmmm. Usually when I think about how long it takes to do something I have to think about the rate it is going.”
1. What is the combined rate of the two hoses in filling the pool? What are the units of the rate?
2. What is the rate of the back-yard hose when it is working alone? What are the units of the rate?
Answer: The rate should normally be in
Gallons per Minute. But here, it might have to be "Pool per Hour" since the total volume is not given.
With two hoses taking 12 minutes, the rate is 5 pools per hour.
Step-by-step explanation:
Take the time to fill with two hoses, double that to get the time for two hoses with equal rates. 24 minutes. But one takes 10 minutes more, so split that. 24 + 5 is 29 minutes. 10 less is 19 minutes. Or try 27 and 17.
If you assume a typical kiddie pool 4 ft diameter and 1 ft deep, not quite full, that would hold around 84 gallons.
84÷12 = 7 gallons per minute.
84÷ 17 = about 4.9 gpm
84 ÷ 27= 3.1 gpm
So 16 and 6 might be possible times to try for realistic rates.
I realize this is not a complete answer, but it might help.
