Solve the equation below for y.
8x - 2y = 24
A. y= 4x - 12
B. y= 12 - 4x
C. y = 8x - 24
D.y = 4x - 8

Answers

Answer 1
A

Because 8x - 2y = 24 is equal to -2y = -8x + 24 is equal to y = 4x - 12.

Answer 2

The given equation, when solved for y gives y = 4x - 12.

Hence, option A is correct.

Given is an equation 8x - 2y = 24, we need to solve for y.

To solve the equation for y, you need to isolate y on one side of the equation.

Let's do that step by step:

Start with the original equation:

8x - 2y = 24

Get rid of the constant term on the left side by subtracting 8x from both sides:

-2y = -8x + 24

Now, we want to solve for y, so we need to get rid of the coefficient of y (-2).

To do that, divide both sides by -2:

y = (-8x + 24) / -2

Simplify the right side of the equation:

y = -8x / -2 + 24 / -2

Simplify further:

y = 4x - 12

So, the solution for y is:

A. y = 4x - 12

A farmer wishes to enclose a pasture that is bordered on one side by a river (so one of the four sides wont require fencing) She has decided to create a rectangular shape for the area and will use barbed wire to create the enclosure there are 600 feet of wire availible for this project and she will use all the wire. what is the maximum area enclosed by the fence then find the maximum of the function. ...?

Answers

The area enclosed is (2x)(600-2x).(2x)(600−2x)=1200x−4x2
In order to maximize we need the derivative to be equal to 0.y′=1200−8x=0
1200=8x
x=150
Therefore the sides for maximum area are 150*300.
The area is: 45000

Answer:

Area is 45000 square feet.

Step-by-step explanation:

Let x be the length of fenced side parallel to the river side.

Let y be the length of other two sides.

Then,

[tex]x+ 2y 600[/tex]

So, we get [tex]x=600-2y[/tex]

Area of this rectangle = xy

= [tex]y(600-2y)[/tex]

[tex]x=-2y^{2}+600y[/tex]

Now attached is the graph of the area function, which is a parabola opening downward.

We can see ta the maximum area occurs when y=[tex]-600/[2(-2)][/tex] = 150

And [tex]x = 600-2(150)[/tex]

x =[tex]600-300=300[/tex]

Therefore, to maximize the area, the side parallel to the river is to be 300 feet long, and the other two fenced sides should be 150 feet long.

The area is = [tex]300\times150= 45000[/tex] square feet.

A ball on a string moves around a complete circle, once a second, on a frictionless, horizontal table. The tension in the string is measured to be 6.0N . What would the tension be if the ball went around in only half a second?

Answers

The tension in the string balances out, and thus equals the centripetal force of the ball 

T = mv^2/r 

if it only takes half the time to finish one orbit it has to be moving at twice the original speed. 

And since v is squared T will increase by 4 

T' = m(2v)^2/r 

T' = 4mv^/r = 4T 

T' = 24.0 N

I hope my answer has come to your help. Have a nice day ahead and may God bless you always!
Final answer:

If the ball went around in half a second, the tension in the string would be 24.0 N.

Explanation:

To find the tension in the string if the ball went around in half a second, we can use the equation for centripetal force. The tension T in the string provides the centripetal force, which is equal to the mass of the ball times the square of its velocity divided by the radius of the circle:

T = (m * v^2) / r

In this case, the mass of the ball and the radius of the circle remain the same, but the velocity changes. Since the ball takes half the time to complete the circle, the velocity is twice as fast. Therefore, the tension in the string would be four times greater:

Tension = 4 * 6.0 = 24.0 N

Using the 28/36 ratio, determine the maximum allowable recurring debt for someone with a monthly income of $4,850.
a. $388
b. $776
c. $970
d. $1,358

Answers

Answer:

The correct answer is A. $388

Step-by-step explanation:

The 28/36 Rule states that : A household should spend a maximum of 28% of its gross monthly income on total housing expenses and not more than 36% on total debt service.

Maximum expense on housing expense = 28% of 4850

                                                                    = $1358

Maximum expense on total debt service = 36% of 4850

                                                                    = $1746

Therefore, the maximum allowable recurring debt with a monthly income of $4,850 = 1746 - 1358 = $388

Hence, The option A is correct.

The intensity I of light bulb varies inversely as the square of the distance d from the light bulb. Suppose I is 250 w/m^2 when the distance is 5 m. How much farther would it be to a point where the intensity is 40 w/m^2? ...?

Answers

Final answer:

The intensity of a light bulb varies inversely as the square of the distance from the light bulb. To find the distance where the intensity is 40 w/m², use the inverse square law formula to solve for the distance.

Explanation:

The intensity of a light bulb varies inversely as the square of the distance from the light bulb. This means that as the distance increases, the intensity decreases.

If the intensity is 250 w/m² at a distance of 5 m, and we want to find the distance where the intensity is 40 w/m², we can use the inverse square law formula:

I₁d₁² = I₂d₂²

Plugging in the values, we get:

250 × (5)² = 40 × (d₂)²

Simplifying, we find that d₂² = 250 × (5)² / 40

d₂² = 312.5

Therefore, d₂ = √312.5 ≈ 17.68

So, it would be approximately 17.68 - 5 = 12.68 meters farther to a point where the intensity is 40 w/m².

#SPJ12

Sure, let's solve it step by step.

First, we know that the initial intensity (I1) is 250 w/m^2 and the initial distance (d1) is 5 m. We are asked to find a distance where the intensity is 40 w/m^2, which would be our final intensity (I2).

According to the inverse square law, the intensity of light is inversely proportional to the square of the distance from the source, i.e., I ∝ 1/d². Therefore, we can say that I1 * d1² = I2 * d2². This equation allows us to find the distance at which the intensity is I2.

So, substituting the given values in the equation, we have 250 * (5)² = 40 * d2².

Now, we can solve for d2. Rearranging terms, d2 = √((250 * (5)²) / 40), which will give us d2 = 12.5 m.

So, the distance at which the intensity of light is 40 w/m^2 is 12.5 m.

However, we have been asked to find the additional distance that needs to be traveled to reach a point where the intensity is 40 w/m^2. This additional distance is the difference between the final distance (d2) and the initial distance (d1), that is, distance_travelled = d2 - d1 = 12.5 - 5 = 7.5 m.

Therefore, you would need to travel an additional 7.5 m to reach a point with an intensity of 40 w/m^2.

Farmer tom’s chickens and sheep are all in a jumble. he counts 48 heads and 134 legs, how many sheep does he have?

Answers

Chickens have 2 legs and sheep have 4 legs. If x is the number of chickens and y is the number of sheep, then we have the system of equations: x + y = 48, 2 x + 4 y = 134. We can solve this system : x = 48 - y, then we will put it into the 2nd equation: 2 * ( 48 - y ) + 4 y = 134, 96 - 2 y + 4 y = 134, 2 y = 134 - 96, 2 y = 38, y = 38 : 2, y = 19. Answer: Farmer Tom has 19 sheep.

You travel 2,557 km in 190 days how far did you travel per hour

Answers

You travel 1.78 km per hour. I came up with this by takin 190 and multiplying it by 24(the amount of hours in a day). Then, I divided that by 2557 and came up with 1.78.
What it is asking for is a distance over time in HOURS. 
It isn't specific about the distance units so, we can assume km is OKAY to use!

Now we need to convert 190 days to hours. Let's set up some conversion factors. 

1 Day = 24 Hours

[tex] \frac{190 days}{1} * \frac{24 hours}{1 day} [/tex]

I recommend setting up conversions like the way I did above. To do so simply make the units cancel out. Similar to how 3/3 cancel out, units also cancel out in the same way. So when you are trying to figure out whether or not you divide or multiply by the conversion factor simply use this method. Say we had 190 hours, the hours unit would need to be on the bottom, and the days on top. It'd be 1/24, thus you would divide by 24. 

[tex] \frac{190 days}{1} * \frac{24 hours}{1 day} [/tex] = 4560 hours.

Now what it is asking for his a rate of distance per hour. This rate is also called speed. Remember in the statement it said how far per hour. Meaning when dividing the units should look like this: [tex] \frac{km}{hour} [/tex]

[tex] \frac{2557km}{4560hour} [/tex] = 0.5607[tex] \frac{km}{hour} [/tex]

The answer is: 
0.5607[tex] \frac{km}{hour} [/tex]

Lets say I had an 80% in a class, yet I got a 100% percent on the midterm, which is 10% of my grade. What would my new grade be?

Answers

you can do a quick calculation of the grades with their weighted percent!!

if you assume that your grade combines to 100% total, and the midterm that's 10% of your grade has yet to be factored in, this would mean that you've received 90% of your grades. in this 90%, you got an 80.

so, at 90% you scored an 80%. at 10% you scored a 100%. you need to combine the two of these to represent how your assignments/tests/homework combine to 100% (90 of that finished, 10 of that coming from your midterm). create an addition problem that represents this, converting percents to decimals:

(0.90)(0.80) + (0.10)(1.00) = .82, or 82%

your final grade would be an 82% in the class.

Erica went shopping for new clothes for school. She bought a pair of jeans for $70.19 and several shirts for $8.63 each. If x represents the number of shirts she bought, which of the following equations should be used to find y, the total cost of Erica's shopping trip? Explain your choice.

it's at least y=$8.63x+$70.19
Y=70.19+(8.63*X)

To find the total she spent all you have to do is add everything together. The cost of the pants was $70.19, to find how much she spent on shirts you take the amount each shirt was, which in this case is $8.63, and multiply it by how many shirts she bought. We don't know how many shirts she bought so we use the varriable of X to represent that number.
