Take 2 points (J,K)

  • (2,24)
  • (4,20)

\\ \tt\longmapsto m=\dfrac{20-24}{4-2}=\dfrac{4}{2}=2

Equation

\\ \tt\longmapsto K-24=2(J-2)

\\ \tt\longmapsto K-24=2J-4

\\ \tt\longmapsto K=2J+20

Answer:

A trend line is a straight line that illustrates the points on a scatter plot.  

The equation of the trend line is: k = -2j + 24

Step-by-step explanation:

From the graph, we have the following points

(j, k) = (6, 12)(4, 16)

Start by calculating the slope

m = k2 - k1 / j2 - j1

So, we have:

m= 16 - 12 / 4 - 6

m = 4 / -2

m= -2

The equation is then calculated as:

k=m(j – j1) + k1

This gives:

k= -2(j - 6) +12

Expand

k= -2j + 12 +12

k= -2j + 24

Complete the diagram to find 430 percent of 90
ludmilkaskok [199]

The easiest way to find percent is to make the percent into a decimal and multiply. Move the decimal to places to the left to make 4.30, and multiplied by 90 equals 387, so 430 percent of 90 is 387.

Dovator [93]

Answer:

The constant term in the polynomial is 140 and it represents the revenue when the price is not increased.

Step-by-step explanation:

To find: What is the constant term in the polynomial expression, and what does it represent?

The given expression is -8x^2 + 54x + 140.

To find the constant term we can simply put x=0 in the given equation where x represents the number of $1 increase in price.

=-8(0)^2 + 54(0) + 140

=140

The constant term is 140 and it represents the revenue when the cost of a hot dog is $2.

Hence, the constant term in the polynomial is 140 and it represents the revenue when the price is not increased.
