Answer:

A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. One absolute rule is that the first constant "a" cannot be a zero.

Two equations are

[tex]\dfrac{50}{x}=\dfrac{10}{20}[/tex]

[tex]\dfrac{10}{50}=\dfrac{20}{x}[/tex]

To find:

The reason for same solutions to the proportions.

Solution:

First equation is

[tex]\dfrac{50}{x}=\dfrac{10}{20}[/tex]

On cross multiplication, we get

[tex]50\times 20=10\times x[/tex]

[tex]1000=10x[/tex]

Divide both sides by 10.

[tex]\dfrac{1000}{10}=x[/tex]

[tex]100=x[/tex]

The second equation is

[tex]\dfrac{10}{50}=\dfrac{20}{x}[/tex]

On cross multiplication, we get

[tex]10\times x=50\times 20[/tex]

[tex]10x=1000[/tex]

Divide both sides by 10.

[tex]x=\dfrac{1000}{10}[/tex]

[tex]x=100[/tex]

Solutions to the proportions are same because both result in the equation 10 x = 1,000, which simplifies to x = 100.

Therefore, the correct option is D.

7.) slope=-2/5   y-intercept= -2  

8.)   slope= -4/9 y-intercept=-3

9.)   slope=1/5  y-intercept=5

10.)m= -3

 11.)m=  2/5

12.)m=2.5

Step-by-step explanation:

The required slope of the line through the points (-6, 3) and (-7,-4) is m = 7.

Given that,
To determine the slope of the line through the points (-6, 3) and (-7,-4).

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The slope of the line is given by,
m = (y₂ - y₁) /  (x₂ - x₁)
Substitute the point in the above equation,
m = 3 + 4/ -6 + 7
m =7 / 1
m = 7

Thus, the required slope of the line through the points (-6, 3) and (-7,-4) is m = 7.

Answer:

(5, -3)

Step-by-step explanation:

when you reflect across x axis the y changes symbols.

The Point A(5, 3) is reflected across the x-axis, then the coordinate of the image is (5, -3).

A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you flipped the form over the line in order to graph a reflection.

Given:

The point A(5, 3) is reflected across the x-axis.

The reflection across the x-axis:

The rule for a reflection over the x-axis is,

(x, y) → (x, −y).

So, the image point,

(5, 3) → (5, −3)

Therefore, the image point is (5, −3).

The value of 0.02 is 10 times greater than the value of 0.002.

If two given numbers are not equal, we use inequality. It means that the first number is either greater than or less than the second number.

Answer:

$33.32

Step-by-step explanation:

f(x)=5.32+0.80(35)

    =5.32+28

    =$33.32

The required cost of mail of the object of 35 pounds is $33.32.

Given that,
f(x)=5.32+0.80x represents the cost of mailing an object that weighs x pounds.
To determine how much would it cost to mail an object that weighs 35 pounds.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
function f(x) represents the cost of mail of x weigh object,
Now for the x = 35
f(x) = 5.32 + 0.80 * 35
f(x) = 5.32 + 28
f(x) = 33.32

Thus, the required cost of mail of the object of 35 pounds is $33.32.

Answer: 127 degrees

Step-by-step explanation:

I hope this helps

E                       F

H                     G

I had to write it out the parallelogram so I could have a better visual.

F and G are consecutive angles in a parallelogram (not on opposite sides).

This means they add to be 180 degrees.

F+G=180

(3x-10)+(5x+22)=180

(3x+5x)+(-10+22)=180

8x       +12=180

Subtract 12 on both sides:

8x           =180-12

Simplify:

8x           =168

Divide both sides by 8:

x              =168/8

x              =21

If x=21 and want the measurement of angle G, then

(5x+22)=(5*21+22)=127.

So angle G has measurement 127 degrees.

The the measure of angle G will be 127°. Then the correct option is D.

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

In parallelogram, the sum of the two adjacent angle is 180 degrees.

In parallelogram EFGH, the measure of angle F is (3x − 10)° and the measure of angle G is (5x + 22)°.

The angle F and angle G are the adjacent angle.

The sum of angle F and angle G is 180°.

             ∠F + ∠G = 180°

3x - 10 + 5x + 22 = 180

                      8x = 168

                        x = 21

Then the the measure of angle G will be

∠G = (5x + 22)°

∠G = (5 × 21 + 22)°

∠G = (105 + 22)°

∠G = 127°

The the measure of angle G will be 127°.

Then the correct option is D.

Answer [tex]\frac{11}{2}[/tex]

Step-by-step explanation:

We must create the equation from the information. Well, we know that there is a 75 dollar fee right off the top, and there is the word "plus" in the information meaning there will be adding.

1. Add the given cost plus the addition sign.

75 + ___ = ?

Now, we must find out what fills in "__." It says that it costs $20 per hour to rent the limo. However, it doesnt tell you how many hours it is being rented for, however it does say that the amount of hours is represented by T. So, fill in that information.

2. Fill in the second number.

75 + 20T = ?

Since there isn't a number to finish the second number to the equation, we know that there isn't going to be a completed answer. So, fill in the final cost with "c" as explained in the equation.

3. Write the answer.

75 + 20T = c

So, the equation to this problem is:

75 + 20T = c

Which is how to find out how much the limo costs to rent it.
