-4x-y=24 can you guys please help me pretty please!?
Answer:
x=-y/4 +6
Step-by-step explanation:
First, y to each side.
-4x=y+24
Second, leave the x by itself by dividing both sides by - 4.
x=-y/4 +6
5. Given y = -1/2x + 10, determine if -2x +2y = 20 is parallel, perpendicular, or neither.
Answer:
Neither
Step-by-step explanation:
-2x+2y=20
First, you need to transfer the [-2x+2y=20] equation to slope intercept form. First, get the y variable on one side by subtracting -2x from the left side.
So then you have
2y= 2x+20
Then you divide the 2 from the y on BOTH side
y= x+10
Now compare the slope of both equations
y= -1/2x+10 (slope= -1/2)
y=x+10 (slope= 1)
Since the parallel slope to -1/2 is the same slope
Since the perpendicular slope to -1/2 is equal to 2/1 or 2,
Neither of them work

PLEASE HELP!!
1y+14=-4y+9 for y. Round your answer to the nearest tenth.
Answer:
y = -1.0
Step-by-step explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, add 4y and subtract 14 from both sides:
1y (+4y) + 14 (-14) = -4y (+4y) + 9 (-14)
1y + 4y = 9 - 14
Combine like terms:
5y = -5
Isolate the variable, y. Divide 5 from both sides:
(5y)/5 = (-5)/5
y = -5/5
y = -1
y = -1 is your answer.

Step-by-step explanation:
Stephon is buying some snacks for his siblings at a convenience store. He wants to buy at least 6 items, but he has only $12 in his pocket. One bag of chips costs $2.25, and one candy bar costs $1.50. Which graph represents the number of bags of chips and candy bars Stephon can buy?
Answer:
Stephon can buy total 4 chips bag and 2 candy bar
Given as :
The money which Stephon has in his pocket = $ 12
The cost of one chips bag = $ 2.25
The cost of one candy bar = $ 1.50
The total number of items he can buy = 6
So, Let the number of chips bag he can buy = x
∴ The number of candy bar he can buy = 6 - x
Now, according to question
The number of chips bag×The cost of one chips bag + The number of candy bar×The cost of one candy bar = $ 12
Or, x × $ 2.25 + (6-x) × $ 1.50 = $ 12
Or, x × $ 2.25 + 9 - x × $ 1.50 = $ 12
or, x × $ 0.75 = 12 - 9
or, x = = 4
The number of chips bag he can buy = x = 4
And The number of candy bar he can buy = 6 - x = 6 - 4 = 2
Hence Stephon can buy total 4 chips bag and 2 candy bar .

Answer:
3/4
Step-by-step explanation:
The mean of a data set is synonymous with the average. To find the mean, add up all the values in the data set and then divide by the number of elements.
From the table, there is 12 values. Thus, add up all the 12 values and then divide by 12:
[tex]\bar x=\frac{(-3)+4+8+(-1)+(-4)+(-2)+0+2+5+2+(-3)+1}{12}[/tex]
Simplify:
[tex]\bar x=\frac{9}{12}[/tex]
Reduce:
[tex]\bar x=3/4[/tex]
Therefore, the mean of the data set is 3/4.
For the data set, this means that the average person guesses the temperature too high by about 3/4°F.
(Note: the symbol of x with a bar over it denotes the mean of a set)

Last month Bill spent $6,000. How much did bill spend on taxes last month? (1) The total amount Bill spent on taxes was 70% of the amount he spent on groceries. (2) 40% of the total amount Bill spent last month was spent on taxes and groceries.
Answer:
Bill spent $988 on taxes.
Step-by-step explanation:
First, you have to find the total amount that Bill spent last month on taxes and groceries as the statement says that he spent 40% of the total amount on that:
$6,000*0.4=$2,400
Then, the statement indicates that the total amount Bill spent on taxes was 70% of the amount he spent on groceries.
Let's consider that:
x=taxes
y=groceries
With the information we can write the following:
x+y=2,400 (1)
x=0.7y (2)
You can replace 2 in 1:
0.7y+y=2,400
1.7y=2,400
y=2,400/1.7
y=1,412
Then, you can replace the value of y in 2:
x=0.7(1,412)
x=$988
According to this, Bill spent $988 on taxes.

Q: Is there a relationship between the sum of each pair of integers and the distance between them? If so, explain.
A: No
I don't know if this is right but I just put this because no one answered this question. Hope this helps someone! :)
Answer:
No, there is no relationship
Step-by-step explanation:
Since there are no pairs of integers, I will give a general answer.
The distance between any two numbers is the absolute value of their difference.
For example we need a distance between numbers of x and y, then we just subtract them in any order and take absolute value of it:
d= | x - y |or
d = | y - x |There is no relationship between the sum of the numbers.
It would make sense only in case one of the numbers is zero. Then the sum or difference would be same.
A 10 ounce box of cheerios cost $2.80 ounce box of cheerios cost $5.20. which is cheaper by the ounce.
Answer: 20 ounces box of cheerios is cheaper.
Step-by-step explanation:
If 10 ounce box of cheerios cost $2.80 and 20 ounce cost $5.20 then to find which is cheaper, you need to find the unit price which is the cost of an ounce.
Divide the money by the amount of ounces.
2.80 / 10 = 0.28 which is 28 cents per ounce.
5.20/20 = 0.26 which is 26 cents per ounce.
So the 20 box of cheerios is cheaper because it is 2 cents less.

Which statement describes function composition with respect to the commutative property?
O Given f(x) = x2 - 4 and g(x) = x-3, (fºg)(2) = -3 and (gºf)(2) = -3, so function composition is commutative.
O Given f(x) = 2x-5 and g(x) = 0.5x - 2.5, (fºg)(x) = x and (gof)(x) = x, so function composition is commutative
Given f(x) = x? and g(x)=xx. (fºg)(0) = 0 and (gºf)(0) = 0, so function composition is not commutative.
O Given f(x) = 4x and g(x) = x? (fog)(x) = 4x2 and (gºf)(x) = 16x?, so function composition is not commutative
Answer:
Given f(x) = 4x and g(x) = x², (f ∘ g)(x) = 4x² and (g ∘ f)(x) = 16x², so function composition is not commutative.
Step-by-step explanation:
Option D is correct, given f(x) = 4x and g(x) = x², (fog)(x) = 4x² and (gof)(x) = 16x², so function composition is not commutative.
What is a function?A relation is a function if it has only One y-value for each x-value.
Function composition is not commutative in general, meaning that (fog)(x) is not equal to (gof)(x) for all functions f and g.
Let f(x) = 4x and g(x) = x², for which function composition is not commutative.
If we compose f and g, we get:
(fog)(x) = f(g(x)) = f(x²) = 4x²
If we compose g and f, we get:
(gof)(x) = g(f(x)) = g(4x) = (4x)² = 16x²
Since (fog)(x) is not equal to (gof)(x) for all x, we can conclude that function composition is not commutative in this case.
Hence, f(x) = 4x and g(x) = x², (fog)(x) = 4x² and (gof)(x) = 16x², so function composition is not commutative, option D is correct.

Remove all perfect squares from inside the square root. Assume bbb is positive. \sqrt{80b^2}= 80b 2
Answer:
Step-by-step explanation:
sqrt(80b^2) can be also written as sqrt(16(5)b^2).
The property sqrt(x*y) = sqrt(x) * sqrt(y) allows us to factor out square root of 16. Thus,
sqrt(16) * sqrt(5) * sqrt (b^2)
4*sqrt(5)*sqrt(b^2)
Sqrt(b^2) is the same as b^2/2, so Sqrt(b^2)= b
final answer 4b * sqrt(5)

Find the arc length of the semicircle. Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi and enter your answer as a decimal.
Answer:
[tex]3.14r[/tex] or [tex]\pi r[/tex]
Step-by-step explanation:
Given:
A semicircle.
To find:
Arc length of the semicircle = ?
Solution:
Formula for angle subtended by an arc on the center of circle is given as:
[tex]\theta = \dfrac{l}{r}[/tex]
where [tex]l[/tex] is the arc length and
[tex]r[/tex] is the radius of semicircle.
Angle of full circle is [tex]2\pi[/tex]
So, angle of semicircle = [tex]\pi[/tex]
Using the formula, we can see that:
[tex]l = \theta \times r[/tex]
[tex]\Rightarrow l = \pi \times r\\\\OR\\\Rightarrow l = 3.14r[/tex]
So, the answer is:
Arc Length of semicircle = [tex]3.14r[/tex] or [tex]\pi r[/tex]

solve the equation for k-2/4 = 10 Help solve this question please.
Answer:
I think K = 10.5
Step-by-step explanation:
First you would do the division of 2/4 which equals 0.5. Now the equation is k-0.5 = 10. If you flip the equation around it is 10 + 0.5 = k. Now you would know that k = 10.5 to check it does 10.5 - 0.5 = 10? Yes.
