Consider the function.

f(x)= -2/3x-24

Which conclusions can be drawn about f–1(x)? Select two options.
f–1(x) has a slope of .
f–1(x) has a restricted domain.
f–1(x) has a y-intercept of (0, –36).
f–1(x) has an x-intercept of (–36, 0).
f–1(x) has a range of all real numbers.

Answers

Answer:

c and e

Step-by-step explanation:

The conclusions about f⁻¹(x) are ; f⁻¹(x) has a y-intercept of (0, -36) and (e); f⁻¹(x) has a range of all real numbers.

How to determine the conclusions?

The function is given f(x) = -2/3x - 24

Express f(x) as y;

y = -2/3x - 24

x = -2/3y - 24

Add 24 to both sides;

x + 24 = -2/3y

Make y the subject,

y = -3/2x - 36

Rewrite

f⁻¹(x) = -3/2x - 36

A linear equation is represented y = mx + b

Where, m represents the slope and b represents the y-intercept

This means :

Slope = -3/2

Y-intercept = -36 or (0,-36)

A train covers 165 km in 1.5 hours. Find the constant variation.

Answers

Answer:

Step-by-step explanation:

110

The required value of constant variation would be 110.

What is the distance?

Distance is defined as the product of speed and time.

Direct variation equation can be written as:

y = kx where "k" is a constant variation.

Here y represents the distance covered by the train, and x represents the time duration.

As per the given question,

Since the train covers 165 km in 1.5 hours.

Substitute the values of y = 165 and x = 1.5 in the direct variation equation and solve for k:

⇒ 165 = 1.5k

⇒ k = 165/1.5

Apply the division operation, and we get

⇒ k = 110

Therefore, the required value of constant variation would be 110.

Decide if each pair of values could be a combination of raisins and walnuts that Diego bought.



4 pounds of raisins and 2 pounds of walnuts

Answers

Answer: You could only buy 1 pound of raisins and 1 pound of walnuts

Step-by-step explanation:

$8=1 pound of walnuts

$15-$8=$7

$4=1 pound of raisins

$7-$4=$3

$3 is not enough to buy a pound of raisins since it’s one dollar off but it is also not enough to buy a pound of walnuts because it’s off by $5

Answer:

4 pounds of raisins and 2 pounds of walnuts is not a solution to this equation.

Step-by-step explanation:

4y+8x=15

4(4)+8(2)=?

4(4)=16

8(2)=16

16+16=32

Therefore, 4 pounds of raisins and 2 pounds of walnuts is not a possible solution for the constraints of the eqution.

In golf, shooting par is scored as a 0. A score of 2 below par on a hole in golf is called an eagle. Jacob’s friend Michelle scored an eagle on each of her first five holes. Explain how you would use addition to find the product of –2 and 5 using the integer tiles and the number line. Please help I need this done quick or I get 0 on my test.

Answers

If you want to use integer tiles to find the product of 2(-5), think of it as you having 2 groups of 5 negative tiles, that is

-1 -1

-1 -1

-1 -1

-1 -1

-1 -1

Think of it as you having each of the -1 inside it's distinct tile. Now adding up these tiles you have -10.

Therefore 2(-5) is -10 using integer tiles.

If we are to use the number line, first draw your number line, then think of it as jumping twice while each jump is -5 big.

So the first jump from 0 will land on -5 and the second jump will land on -10 and that is the required answer using the number line.

Step-by-step explanation:

x-5 + 2x+ 5 + 75 = 180

3x + 75= 180

3x= 105

x= 35

Hope this helps

Answer:

Angle OXP = 105 degrees.

Step-by-step explanation:

Let's start figuring out the angles in the triangle.  We know that the sum of the interior angles of a triangle add up to 180.

(x - 5) + (2x + 5) + 75 = 180

x - 5 + 2x + 5 + 75 = 180

3x = 105

x = 35

So angle FXO = 2x + 5 = 2(35) + 5 = 70 + 5 = 75

We know that angle FXO and OXP are supplementary angles, so they add up to 180 degrees as well.

OXP = 180 - 75 = 105

width in inches. Make a table showing the area of the rectangles with a 5-inch length and a
width of 2, 4, 6, and 8 inches. What would be the ordered pairs on the table.

Answers

Answer:

Width 2 4 6 8

Area 10 20 30 40

Step-by-step explanation:

Area of a rectangle = length × width

Calculate width when length = 5 inches

When length = 5 inches and width = 2 inches

Area of a rectangle = length × width

A = 5 × 2

= 10 square inches

When length = 5 inches and width = 4 inches

Area of a rectangle = length × width

A = 5 × 4

= 20 square inches

When length = 5 inches and width = 6 inches

Area of a rectangle = length × width

A = 5 × 6

= 30 square inches

When length = 5 inches and width = 8 inches

Area of a rectangle = length × width

A = 5 × 8

= 40 square inches

Given the same length and different width

Width 2 4 6 8

Area 10 20 30 40

Matthew and Mark were selling cups of lemonade. Matthew sold 15 more cups of lemonade than Mark. Together they sold 81 cups. How many cups did Matthew sell?

Answers

Answer:

48 cups

Step-by-step explanation:

Matthew and Mark were selling cups of lemonade.

Let the number of cups that Matthew sold = x

The number of cups Mark sold = y

Together they sold 81 cups.

= x + y = 81 cups...... Equation 1

Matthew sold 15 more cups of lemonade than Mark.

x = y + 15 cups

Substituting y + 15 for x in Equation 1

y + 15 + y = 81 cups

2y +15 = 81 cups

2y = 81 -15

2y = 66 cups

y = 66 cups/2

y = 33 cups

Hence, the number of cups Mark sold = 33 cups.

The number of cups Matthew sold is calculated as:

= x = y + 15 cups

x = 33 cups + 15 cups

x = 48 cups

find the equation of the line with the slope m= -6 that passes through the point (-3, -5). Write the equation in the form Ax+ By=C

Answers

Answer:

y=mx+b

-5= -3(-6)+b

-5=18+b

-23=b

3x-5y=-23

The equation of the line with slope m = -6 that passes through the point (-3, -5) in the form Ax + By = C is 6x + y = -23.

We have,

To find the equation of a line given its slope and a point on the line, we can use the point-slope form of the equation, which is:

y - y1 = m(x - x1)

Where (x1, y1) represents the coordinates of the given point and m is the slope.

Given the slope m = -6 and the point (-3, -5), we can substitute these values into the point-slope form:

y - (-5) = -6(x - (-3))

Simplifying:

y + 5 = -6(x + 3)

Expanding the equation:

y + 5 = -6x - 18

To write the equation in the form Ax + By = C, we need to rearrange it:

6x + y = -18 - 5

6x + y = -23

The coefficients of x and y are 6 and 1 respectively, so the equation can be written as:

6x + y = -23

Therefore,

The equation of the line with slope m = -6 that passes through the point (-3, -5) in the form Ax + By = C is 6x + y = -23.
