Answer:

y = -3,-4

Step-by-step explanation:

Factor the equation, which gives you (y+3)(y+4)=0

Then, all you do is find the values that give the equation an answer of 0.

Since anything times 0 is 0, all you have to do is make one of the (y+x) values equal 0.

Since -3 and -4 added to 3 and 4 make 0 the answers are -3 and -4.

You can check by plugging it back into the equation or graphing it.

Answer:

School A gave 12 correct and 12 incorrect answers. School B gave 12 correct answers and the competition was tied.

Step-by-step explanation:

We are given the following information:

School A points = 174

School B points = 102

Every correct answer is awarded 10 points and every incorrect answer reduces 6 points.

Let x be the number of correct answer given by school A and thus x is the number of  incorrect answer given by school A. The, school B also gives x number of correct answer.

Thus, the scored can be modeled with the following equations:

School A: [tex]174 + 10x - 6x = 174 + 4x[/tex]

School  B: [tex]102 + 10x[/tex]

Since, both the schools tied, equating both the equations:

[tex]174 + 4x = 102 + 10x\\\Rightarrow 10x - 4x = 174 -102\\\Rightarrow 6x = 72\\\Rightarrow x= 12[/tex]

Thus, school A gave 12 correct and 12 incorrect answers. School B gave 12 correct answers and the competition was tied.

Answer:

$1,953

Step-by-step explanation:

So, we need to figure out how many times the big warehouse is actually bigger than the small one, in order to calculate the air conditioner cost for the large warehouse.

Let's say x represents the dimensions of the small warehouse, and y represents the dimensions of the large warehouse.

We have y = 2.5x, for every dimension (length, width, height)

The formula to calculate the volume of a cubic space is the following:

volume = length * width * height

Now, we don't know the exact measurements involved, but we know the large warehouse is 2.5 times bigger in every dimension, so...

volume = 2.5x * 2.5x * 2.5x = 2.5³x³ = 15.625 x³

So, the larger warehouse is 15.625 times larger than the small one.  We then multiply that by the cost of cooling down the small warehouse:

cost for large warehouse = 15.625 * $125/month = $1,953.25

Rounded to the nearest dollar: $1,953

Final answer:

The input value for an output of -4 for the function g(x) = 28/x - 7 is x = 28/3.

Explanation:

To find the input value for a given output value of a function, we need to set the function equal to the output value and solve for the variable. The student is asking for the input value that results in an output of -4 for the function g(x) = 28/x - 7. To solve for x, we follow these steps:

Set the function g(x) equal to -4: g(x) = -4.

Substitute g(x) with the function definition: -4 = 28/x - 7.

Isolate the term with x by adding 7 to both sides: -4 + 7 = 28/x.

Simplify the left side of the equation: 3 = 28/x.

To find x, multiply both sides by x and then divide by 3: x = 28/3.

Therefore, the input value for an output value of -4 for the function g(x) = 28/x - 7 is x = 28/3.

Answer:

The solution in point form is (9,7) and the equation would be x+9, y=7

Step-by-step explanation:

By using moving the -4y to the right side and by flipping the signs you can turn the equation -x-4y=-37 into x=37-4y.

With this new equation you can use the substitution method and replace the x in -2x-5y=-53 with 37-4y, making it look like this: -2(37-4y)-5y=-53.

Then you solve for y getting y=7.

With the value of y, you can plug that into the equation x=37-4y so it will look like x=37-4(7)

Then you solve for x getting x=9

And with that you get the point (9,7)

[tex]slope=\dfrac{15-3}{5-1}=\dfrac{12}{4}=\boxed{3}[/tex]

4) Average rate of change is the slope of the given interval:

a) when x = 0, y = 0 and when x = 1, y = -3

   [tex]Slope=\dfrac{-3-0}{1-0}=\dfrac{-3}{1}=-3[/tex]

b) when x = -2, y = 0 and when x = -1, y = 3

   [tex]Slope=\dfrac{3-0}{-1+2}=\dfrac{3}{1}=3[/tex]

c) when x = 0, y = 0 and when x = 2, y = 0

   [tex]Slope=\dfrac{0-0}{2-0}=\dfrac{0}{2}=0[/tex]

Answer:

A: y = 4x + 7

Step-by-step explanation:

Step 1:  Our line is parallel to this line, so it has the same slope, but a different  y-intercept, so set up the equation...

  y = 4x + b      

We are given a  point (x, y) of (2, 15), so plug that in and solve for b.  

 15 = 4(2) + b

    15 = 8 + b      (simplify)

        7 = b      (subtract 8 from both sides to isolate b)

So the equation of our line is  y = 4x + 7

Step-by-step explanation:

1. When a number is divisible by 2 it must end with even digit 0, 2, 4, 6 or 8.

So the number 24,515 is not divisible by 2.

2. When a number is divisible by 5 it must end with  digit 0,  or 5.

The number 24,515 ends with 5 so it is divisible by 5.

3. When a number is divisible by 3, the sum of all digits must be divisible by 3.

The sum of all digits of the number 24,515 is 2+4+5+1+5=17. 17 is not divisible by 3, so the number 24,515 is not divisible by 3.

4. When a number is divisible by 9, the sum of all digits must be divisible by 9.

The sum of all digits of the number 24,515 is 2+4+5+1+5=17. 17 is not divisible by 9, so the number 24,515 is not divisible by 9.

Answer:

The length of its diagonal is [tex]27.01\ m[/tex]

Step-by-step explanation:

Let

b------> the length side of the square

d-----> the diagonal of the square

we know that

The perimeter of the square is

[tex]P=4b[/tex]

[tex]P=76.4\ m[/tex]

Find the value of b

[tex]4b=76.4[/tex]

[tex]b=76.4/4=19.1\ m[/tex]

Applying the Pythagoras theorem find the length of the diagonal

[tex]d^{2}=19.1^{2}+19.1^{2}\\ \\d^{2}=729.62\\ \\ d=27.01\ m[/tex]

The length of the diagonal of a square is approximately 27.02m.

The perimeter of a square is the total length of all four sides of the square. Since we know that the perimeter is 76.4 meters, we can calculate the length of one side by dividing the perimeter by 4.

Length of one side = Perimeter ÷ 4 = 76.4m ÷ 4 = 19.1m.

To find the length of the diagonal, we can use the Pythagorean theorem for a square, which is a² + a² = diagonal². Here, a is the length of one side of the square. Thus, diagonal² = 2 × (19.1m)².

Diagonal = √(2 × (19.1m)²) = √(2 × 364.81m²) = √729.62m² = 27.02m (rounded to two decimal places).

Therefore, the length of the diagonal of the square is approximately 27.02 meters.
