Find the inverse function in slope-intercept form (mx+b):


f(x) = - 3x + 9

13 points

Answers

Answer 1

Answer:

y= 3- x/3

Step-by-step explanation:

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables: y=9−3x so it becomes x=9−3y.

Now, solve the equation x=9−3y for y. You would just need to leave y alone so you divide by 3 on both sides (NOT negative 3. Just 3.)

Answer 2

Answer:

y=(-x/3)+3

Step-by-step explanation:

y=-3x+9

x=-3y+9

x-9=-3y, next division

(x-9)/-3=y

simply and rearrange

y=(-x/3)+3

Answers

Answer:

Angle x is 38.

Step-by-step explanation:

If its congruent it means it is equal. Vertical angles are equal to each other.

The measure of x is 38°.

What are corresponding angles?

The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.

Corresponding angles are equal.

We have,

Vertical angles are congruent.

x° and 38° are vertical angles.

Now,

x° = 38°

Thus,

The value of x is 38°.

The digits of a two-digit number sum to 8. When the digits are reversed, the resulting number is 18 less than the original number. What is the original number?
26
35
53
62

Answers

Answer:

original number = 53

Step-by-step explanation:

In two digits number:

Let the tens place digit be x and units place digit be y.

So,

Original number = 10x + y

Number obtained after reversing the digits = 10y + x

According to the first condition:

x + y = 8.... (1)

According to the second condition:

10y + x = 10x + y - 18

10y + x - 10x - y = - 18

9y - 9x = - 18

-9(x - y) = - 18

x - y = - 18/(-9)

x - y = 2.......(2)

Adding equations (1) & (2), we find

x + y + x - y = 8 + 2

2x = 10

x = 10/2

x = 5

Plug x = 5 in equation (1), we find:

5 + y = 8

y = 8 - 5

y = 3

10x + y = 10*5 +3 = 50 + 3 = 53

Hence, original number = 53

Determine the slope intercept form of the linear equation from its graph.​

Answers

Given:

The graph of linear function.

To find:

The slope intercept form of the linear equation from the given graph.

Solution:

The slope intercept form of a linear function is:

[tex]y=mx+b[/tex]

From the given graph it is clear that the graph passes through the points (1,300) and (4,800).

The equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-300=\dfrac{800-300}{4-1}(x-1)[/tex]

[tex]y-300=\dfrac{500}{3}(x-1)[/tex]

[tex]y-300=\dfrac{500}{3}x-\dfrac{500}{3}[/tex]

Adding 300 on both sides, we get

[tex]y=\dfrac{500}{3}x-\dfrac{500}{3}+300[/tex]

[tex]y=\dfrac{500}{3}x+\dfrac{900-500}{3}[/tex]

[tex]y=\dfrac{500}{3}x+\dfrac{400}{3}[/tex]

Therefore, the required equation is [tex]y=\dfrac{500}{3}x+\dfrac{400}{3}[/tex].

Find the ratio created when AB is partitioned by C.

Write your ratio with a, : and do not include spaces.

Answers

Answer:

Step-by-step explanation:

From the picture attached,

Segment AB has been divided into four equal parts.

Let each part measures equal length = 1 unit

Point C is 2 units apart from both the points A and B.

Length of AC = Length of BC = 2 units

Therefore, point C will be the mid point of segment AB.

And ratio of AC and BC = 1:1

AC:BC = 1:1

Similarly, AC:AB = 2:4

                           = 1:2

And BC:AB = 2:4

                   = 1:2

Write a slope intercept equation for this situation.

A computer technician charges $60 to come to your house and $18 for each hour he works.​

Answers

Answer:

y = 18x + 60

Step-by-step explanation:

The slope intercept equation is:

y = mx + b

For this problem:

y will represent the total cost of the technician

m will represent cost per hour

x will represent number of hours

b will represent the initial cost

With this in mind, we can plug these into our equation

y = 18x + 60

Answer:

in slope intercept this would look like y = 18x + 60

Question: what is the value of x?

Answers

Answer:

x = 48 (in degrees, I assume)

Step-by-step explanation:

Note that the two horizontal lines have those extra arrowheads on them? The red ones? That notation means those lines are parallel to each other.

In geometry, we learn that when two parallel lines are crossed by a third line (called a 'transversal'), alternate interior angles are congruent.

The two angles with labeled quantities are alternate exterior angles. They are 'alternate' because they are on opposite sides of the transversal line, and 'exterior' because they are above and below the the two horizontal lines, not contained in the interior area between them.

Therefore,       2x + 2 = x + 50

                         -x - 2 = -x -  2

                          x       =    48
