A function assigns the values. The function for this model can be written as y=-4x+50.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

As it can be seen from the graph that the function is linear, therefore, we can write,

y = mx + c

Given two points of the graph, therefore, we can write for the first point,

30 = m(5) + c

30 = 5m + c

c = 30 - 5m

Also, for the second point,

y = mx + c

26 = 6m + c

Substitute the value of c,

26 - 6m = 30 - 5m

-6m + 5m = 30 - 26

-m = 4

m = -4

Now, substitute the value of m in any one of the equation formed above,

c = 30 - 5m

c = 30 - 5(-4)

c = 50

Hence, the function for this model can be written as y=-4x+50.

Sever21 [200]
432 characters can be expected to fit per yard of text. The following solution can be used:
Let x be the number of characters to be used in a yard
12 characters / in = x/ 36 in
(12 characters * 36 in) / in = x
x = 432 characters

The area of a football field is 57,600 square feet. If the width of the field is 4/9 the length, what is the length of the footb
MrRissso [65]

Answer:

360 ft

Step-by-step explanation:

<h3>Given</h3>
  • Area = 57600 ft²
  • Length = x
  • Width = 4/9x
<h3>Solution</h3>
  • A = lw
  • x*4/9x = 57600
  • 4/9x²= 57600
  • x² = 57600*9/4
  • x² = 129600
  • x = √129600
  • x = 360 ft
