Answer:

Equation of line passing through points is: [tex]y=\frac{7}{2}x-6[/tex]

Step-by-step explanation:

Given points are;

(-4, -20) and (12, 36)

First we will find slope of the equation,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m = \frac{36-(-20)}{12-(-4)}\\\\m = \frac{36+20}{12+4}\\\\m = \frac{56}{16}\\\\m = \frac{7}{2}[/tex]

Equation of a line is given by;

y = mx + b

Putting (-4, -20) in this equation to find b.

[tex]-20=\frac{7}{2}*-4+b\\-20 = -14 + b \\-20+14 = b \\b = -6[/tex]

The equation is;

[tex]y = \frac{7}{2}x - 6[/tex]

Hence,

Equation of line passing through points is: [tex]y=\frac{7}{2}x-6[/tex]

Answer: C

Step-by-step explanation: As you most likely know, the matrix represents the system of equations. If you assume that x is the far left column, that y is the column adjacent to it, and that y is to the left of the line, you can assume that these are the equations represented:

1x-3y+2z=-9

1x+0y+1z=1

0x+2y-1z=7

which can be simplified to

x-3y+2x=-9

x+z=1

2y-z=7

Step-by-step explanation:

Put it in Desmos, and it’ll show you

The reasonable domain of the function is 8 ≤ x ≤ 24.7.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = -0.5x² + 16x – 96

The function represents the height of a rocket as a function of its horizontal position.

It is reasonable to assume that the rocket is launched from the ground

(x = 0) and that it has some minimum height (above ground level) before it is launched.

Now,

We can find this minimum height by finding the vertex of the parabola, which is given by.

x = -b / (2a)

where a = -0.5 and b = 16.

Plugging in these values, we get.

x = -16 / (2(-0.5))

x = 16

Now,

The vertex occurs at x = 16.

To find the minimum height, we can plug this value into the function.

f(16) = -0.5(16)² + 16(16) - 96

       = 128

Therefore,

The rocket has a minimum height of 128 feet above ground level before it is launched.

To find the reasonable domain of the function.

Since the rocket is launched from the ground at x = 0 and has a minimum height of 128 feet, it is reasonable to assume that the rocket will remain above ground level for all values of x greater than or equal to 8, since the rocket must clear a height of 128 feet by the time it reaches x = 8.

Now,

We can find the x-value where the rocket reaches ground level

(i.e., its height is zero) by setting f(x) = 0.

Solving for x.

-0.5x² + 16x - 96 = 0

Using the quadratic formula.

x = ( -16 ± √(16² - 4(-0.5)(-96)) ) / (2(-0.5))

x = ( -16 ± √(1216) ) / (-1)

x ≈ 24.7 or x ≈ 7.3

Since the rocket is launched from the ground at x = 0, it is not reasonable to consider values of x less than 0.

Therefore,

The reasonable domain of the function is 8 ≤ x ≤ 24.7

This means,

The rocket will remain above ground level for all values of x between 8 and approximately 24.7.

Thus,

The reasonable domain of the function is 8 ≤ x ≤ 24.7.

Solve

In laws of indices, we have:

[tex]\frac{x^m}{x^n} = x^{m-n}[/tex]

Answer: 3

Step-by-step explanation:

I took 4 1/2 and made it an improper fraction which is 9/2 and then I took 3 3/4 and turned it into an improper fraction which is 15/4, so now you need to find the common denomerator which is 8 then you add the numerators which is 9 and 15 is 24 so can be divided by 8 so 24 divided by 8  is 3 and 8 divided by 8 is 1 so now you have another improper fraction 3/1 which is just 3.

Answer:

8/4 or 2

Step-by-step explanation:

2 solutions

The equation 2x - 4 = 4 - 2x has a single solution, x = 2.

The equation 2x - 4 = 4 - 2x can be simplified and analyzed to determine the number of solutions.

First, let's simplify the equation by combining like terms:

4x - 4 = 4

Next, we can add 4 to both sides of the equation to isolate the variable:

4x - 4 + 4 = 4 + 4

This simplifies to:

4x = 8

Now, we divide both sides of the equation by 4 to solve for x:

(4x) / 4 = 8 / 4

This yields:

x = 2

Therefore, the equation 2x - 4 = 4 - 2x has a single solution, x = 2.

This means that when we substitute x = 2 into the original equation, both sides will be equal. Thus, the equation has a unique solution, indicating that the two sides of the equation represent the same line or point of intersection.

In summary, the equation has one solution, which is x = 2.

Let x be the smallest even integer.

Then (x + 2) and (x + 4) are the other even integers.

We have x + (x + 2) + (x + 4) = 138.

Answer:

$0.37

Step-by-step explanation:

You can write this equation as, x=$5.20÷14.

This is because we know we are trying to find the x value for 1 candy bar. and 14 costs $5.20 in total. 14÷14=1. Therefore, we essentially divided the total sum among each individual candy bar. (example: if you wanted to find the value of 2 candy bars, you would take half of 14 and divide $5.20 by 7). $5.20÷14=$0.37 or 37 cents per candy bar.

Writing this as a rate is simple; it's $0.37/candy bar

Answer:

Surface area: 250

Volume: 1375

Step-by-step explanation:

Scale factor: 4:5

This means that the dimensions of the larger figure are 5/4 of those in the smaller figure.

Surface area:

The surface area is found multiplying the square of the change(5/4) by the original surface area(160). So

[tex]S = (\frac{5}{4})^2 \times 160 = \frac{25}{16} \times 160 = 25 \times 10 = 250[/tex]

Volume:

The volume is found multiplying the cube of the change(5/4) by the original volume(704). So

[tex]S = (\frac{5}{4})^3 \times 704 = \frac{125}{64} \times 704 = 125 \times 11 = 1375[/tex]

Answer:

The answer is below

Step-by-step explanation:

Let x be the diameter of the semicircle. radius = x/2

The window is a combination of a rectangle and semicircle.

Width of window = diameter = x, let length of the window = y.

Perimeter of semicircle = πr = πx/2

Perimeter of window = x + y + y + πx/2

20 = x + 2y + πx/2

2y + x + πx/2 = 20

2y = 20 - x(1 - π/2)

y = 10 - x(1 - π/2)/2

Area of semicircle = (1/2)πr² = (1/2)π(x/2)²

Area of window = xy + (1/2)π(x/2)²

A = x(10 - x(1 - π/2)/2) + πx²/8

A = 10x - x² - πx²/4 + πx²/8

A = 10x - x² - πx²/8

The maximum area is at dA / dx = 0

dA / dx = 10 - 2x - 2πx/8

0 = 10 - 2x - πx / 4

2x + πx / 4 = 10

2.785x = 10

x = 3.59 feet

Maximum area = 10x - x² - πx²/8 = 10(3.59) - 3.59² - π(3.59²) / 8

Maximum area = 17.95 feet²

Answer: 0.7, 0.2, 0.1

Step-by-step explanation:

For this question, you have to convert each of the fractions into decimals.

You can directly convert 7/10 into a decimal, this is 0.7

You cannot directly convert 1/5 into a decimal, so you have to convert it into tenths first.

To do this, multiply the numerator and denominator by 2

1 x 2 = 2

5 x 2 = 10

2/10

Now you can convert 2/10 directly into a decimal, this is 0.2

And finally you can convert 1/10 into a decimal, this is 0.1

hope this helps :)
