A local store buys used video games. For each game bought, they will pay $18 less than the original price paid for the game. Which expressions represent the total amount Jordan will receive if he sells “n” games that originally cost “d” dollars each? Check all that apply.

Please find below the given equation-

y + 2 = -2 ( x - 3 )

y + 2 = -2 x - 2(- 3)

y + 2 = -2 x + 6

y = -2 x + 6 - 2

y = -2 x + 4

Let's compare this equation with the form y = mx +c

By comparing we get,

m = -2 and c = 4

We know, in y = mx + c , slope of the line is given by m

Here m = -2, as discussed above

Therefore the slope of the given line is -2

Hope it helps ..!!

Answer:

A circle is the set of all points in a plane that are the same distance from a fixed point called the center.

Step-by-step explanation:

see picture

Circle can be defined as a set of all points in a plane that are the same distance from a fixed point called the center.

A circle has defined the set of all points in a plane that are the same distance from a fixed point called the center. The circle is a 2D shape.

In geometry, the circle is defined as the closed 2-dimensional curved shape. The distance from between the center of the circle to any point on the circle is known as the radius of the circle.

As we have discussed the definition of a circle, therefore, the correct option is 'A circle is the set of all points in a plane that are the same distance from a fixed point called the center.'

Answer:

number of markers Camden has = [tex]5[/tex]

number of markers Carly has = [tex] 25[/tex]

Step-by-step explanation:

Let the number of markers Camden has = x

now it is given that Carly has 5 times as many markers as Camden has

Number of markers Carly has = 5 ( number of markers Camden has )

                                                   = [tex]5x[/tex]

now the total number of markers = 30

number of markers with Carly + number of markers with Camden = 30

so we have

[tex]5x+x = 30[/tex]

[tex]6x =30[/tex]   ( adding like terms x and 5x)

[tex]x=\frac{30}{6}[/tex] ( dividing both sides by 6)

[tex]x= 5[/tex]

hence we have

number of markers Camden has = [tex]x=5[/tex]

number of markers Carly has = [tex]5x= 5(5) = 25[/tex]

Final answer:

Carolyn would use a ruler to measure the length of the piece of ribbon.

Explanation:

To measure the length of a piece of ribbon, Carolyn would use a ruler as the instrument. A ruler is a tool used for measuring small items and distances. It is commonly used for measuring in inches, which is the appropriate unit for short lengths like a piece of ribbon. Carolyn can align one end of the ribbon with the zero mark on the ruler and then extend the ribbon along the ruler to measure its length accurately.

The ruler's precision in measuring small distances, typically in inches, allows Carolyn to obtain a detailed and accurate measurement for the ribbon's length. Aligning the ribbon's end with the ruler's zero mark ensures a standardized starting point for consistency in measurements. This straightforward method showcases the practicality and ease with which rulers facilitate precise length measurements, making them essential tools for tasks requiring accuracy in determining dimensions.

The height of the rocket after 3 seconds is 171 feet.

A function is defined as a relation between the set of inputs having exactly one output each.

The height = -16t² + 91t + 42

After 3 sec means, t = 3, so we substitute t with 3

In order to find the height of the rocket after t seconds we plugin t = 3 in the function.

height H = -16t² + 91t + 42

H = -16(3)² + 91(3) + 42

   = -144 + 273 + 42

   = 171 feet

Thus, the height of the rocket after 3 seconds = 171 feet.

Answer:

Pentagon and an OCTAGON

Step-by-step explanation:

Polygons are are plane figures with three or more sides. Since plane figures with 3sides are triangles and those with 4sides are quadrilaterals, I will take a plane figure of 5sides as one of the two polygons Ellen is drawing

A plane figure with 5sides and 5angles is a PENTAGON

If one of the polygons has 3 more angles than the other, then the other polygon she is drawing was a polygon with (5+3) i.e 8sides and 8angles. This polygon is known as an OCTAGON

Based on the conclusion, the shape Ellen could be drawing is a PENTAGON and an OCTAGON

part A

the x intercept 0 is the point where the ball was hit, the x intercept 20 is the point where the ball fell back to the ground, 20 feet away from the kicker.

the function is increasing in the interval x∈(0, 10) and decreasing in x∈(10, 20) 
this means that the height is increasing in the interval  (0, 10) and decreasing as x goes through the interval (10,20)
the distance from the kicker is increasing during the whole interval (0, 20)

part B

the rate of change represents the slope of the secant line from A to B. It approximates the rate at which f(x) decreases or increases in the interval

To solve the inequality x + 4/2x - 1 < 0, first find the critical value x = 1/2. Then, test the intervals to determine the solution set x < 1/2.

To find the solution of the inequality x + 4/2x - 1 < 0, we can follow these steps:

First, find the critical values by setting the denominator, 2x - 1, equal to zero and solve for x. The critical value is x = 1/2.

Next, test the intervals created by the critical value in the original inequality x + 4/2x - 1 < 0. This helps determine the solution set which is x < 1/2.
