In Exercises 9-12 solve y=f(x) for x then find the input when output is 2 9. F(x)=x+5 10. F(x)=2x-3 11. F(x)= 1/4x -1 12. F(x)= 2/3x+4

Answers

Answer 1

Step-by-step explanation:

Q9 . y = x + 5

x= y-5

× the input

y the output

x= -3

Q10.

y = 2x -3

y+3 = 2x

x = (y+3) ÷ 2

× = 5/2

= 2.5

Q11.

y = 1/4x - 1

y+1 = 1/4 x

4y+4 = x

x = 12

Q 12 .

y = 2/3x + 4

y-4 = 2/3x

3(y-4) = 2x

x = 3(y-4)/2

x = -3

7. Given directed line segment RT below, find the coordinates of S such that the ratio of RS to ST is 5:1. Plot point S​

Answers

A line can be divided in proportions using ratios. The point at which a line is divided in ratios is calculated using: [tex][\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]

The coordinate of S is: [tex](6,\frac{8}{3})[/tex]

Given that:

[tex]RS : ST = 5 : 1[/tex]

The coordinates of RT are not given. So, I will solve using a general explanation.

When a line is divided into ratios, the point (S) at which the line is divided is calculated using the following line ratio formula:

[tex]S = [\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]

Assume the coordinate of R and T is:

[tex]R = (1,6)\\T = (7,2)[/tex]

[tex]RS : ST = 5 : 1[/tex] means:

[tex]m:n = 5:1[/tex]

So, point S is:

[tex]S = [\frac{5\times 7+ 1 \times 1}{5+1},\frac{5 \times 2+ 1 \times 6}{5+1}][/tex]

[tex]S = [\frac{36}{6},\frac{16}{6}][/tex]

[tex]S = [6,\frac{8}{3}][/tex]

Hence, if the coordinates of R and T are:

[tex]R = (1,6)\\T = (7,2)[/tex]

And the line ratio is:

[tex]m:n = 5:1[/tex]

The coordinate of S is:

[tex]S = [6,\frac{8}{3}][/tex]

3. If Adam Ct. is perpendicular to Bertha Dr. and Charles St., what must be true? (1 point)
O Adam Ct. I Edward Rd.
O Bertha Dr. || Charles St.
O Dana La. I Charles St.

Answers

Step-by-step explanation:

Option B. Here Adam Ct. is perpendicular to Betha Dr. and Charles. So, St. Bertha Dr. || Charles St. Since they are parallel to each other

Answer: Bertha Dr. || Charles St.

Step-by-step explanation:

Parallel lines are lines in a plane that do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel.

A line is said to be perpendicular to another line if the two lines intersect at a right angle.

Adam Court is perpendicular to Edward Road.

Bertha Drive is parallel to Charles St.

Dana Lane is perpendicular to Edward Road.

The revenue made by a motorcycle company from the sale of x motorcycles is given by 0.003x^2 + 9x. The cost to produce x motorcycles is given by the polynomial 13x+400,000. Form a polynomial expression written in simplified standard form for the profit from making and selling x motorcycles.

Answers

The profit expression from selling x motorcycles expressed as a polynomial is : -0.003x² + 4x + 400000

The value of profit cab be found using the expression :

Profit = (Cost of production - Revenue)

Profit = (Cost of production - Revenue) Cost of production = 13x + 400000

Profit = (Cost of production - Revenue) Cost of production = 13x + 400000Revenue = 0.003x² + 9x

Profit = (13x + 400000) - (0.003x² + 9x)

Profit = 13x + 400000 - 0.003x² - 9x

Profit = 13x - 9x + 400000 - 0.003x²

Profit = 4x + 400000 - 0.003x²

The polynomial in simplified standard form can be expressed thus : -0.003x² + 4x + 400000

The graph shows the result of matrix operation AB, where the pre-image has dashed lines. Which matrix could represent B?​

Answers

Matrix operations includes the addition, multiplication and subtraction of matrices

The correct option for the matrix that can be used to represent B is option D)

[tex]D) = \left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

The reason the above option is correct is as follows:

From the graph, we have that the coordinates of the preimage are;

(-6, 5), (-3, 9), and (6, 5)

The coordinates of the preimage in matrix form is given as follows;

[tex]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

The coordinates of the image are;

(-6, -5), (-3, -9), and (6, -5)

The coordinates of the image in matrix form is given as follows;

[tex]\left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

The above image matrix can be obtained from the primage matrix as follows:

[tex]\left[\begin{array}{rrr}1&0\\0&-1\end{array}\right]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right] = \left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

Which is of the form AB = C

Where;

[tex]A = \left[\begin{array}{rrr}1&0\\0&-1\end{array}\right][/tex]

[tex]B = \left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

[tex]C = \left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

Therefore, the matrix that could represent B is [tex]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex] which is option D)

If Jordan had his hourly salary increase from $9.25 per hour to $10.75 per hour, which of the following is
closest to the percent increase in Jordan's salary?

Answers

Is this even a question

The solution is,  the percent of the increase is  16.22%.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

If Jordan had his hourly salary increase from $9.25 per hour to $10.75 per hour.

now, we have,

The percent of increase can be calculated as:

vf - vi/ vi * 100

Where vf is the final value and vi is the initial value.

So, replacing vf by 10.75 and vi by 9.25, we get:

1.5 / 9.25 * 100

= 16.22%

Therefore, the percent of the increase is 16.22%
