C = 24,000 + 7x
a)
using y = mx + b where m = slope

so re-write the equation
C = 7x + 24,000

so slope = 7

<span>it represents the cost will be increased $7 if the number of balls increase 1 unit

</span>b)
y intercept when x = 0 so C = 24,000 + 7(0) = 24,000

<span>It means the cost is $2400 when there's no balls produce.
</span>
c)
If spend less than $30,000 then C < 30,000
equation would be
7x + 24,000 < 30,000, solve for x
7x < 6,000
x < 857.14

answer

the maximum number of balls that can be produced is 857

The students in Mrs. Willow's reading class are all reading the same novel independently. Four students create a graph of their

Dovator [93]

Answer:

see the explanation

Step-by-step explanation:

Let

x ----> the time in minutes

y ---> the number of words reading

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem, the relationship between x, and y, represent a proportional variation

The linear equation is equal to

$y=kx$

where

k is the constant of proportionality or the reading rate in words per minute

therefore

The student who reads fastest is the one whose equation has the highest proportionality constant or whose graph has the steepest line slope

Example

If you have

$y_1=23x\\y_2=35x\\y_3=50x\\y_4=20x$

The student who reads fastest is the number 3

Because the value of k=50 words/minute is greater
