The total number of victories for a football team exceeds the number of defeats by 4, with no draws. Knowing that if 44 jojos, h
Leno4ka [110]

Answer: 24

Step-by-step explanation:

Let the number of defeats be represented by x.

Since the total number of victories exceeds the number of defeats by 4, then the number of victories will be:

= x + 4

We then add the number of victories and losses together and equate them to 44. This will be:

x + x + 4 = 44

2x + 4 = 44

2x = 44 - 4

2x = 40

x = 40/2

x = 20

Therefore number of victories will be:

= x + 4

= 20 + 4

= 24

olchik [2.2K]

If the function is y = 4.5x. Then the rate of change of the function expressed as a unit rate will be 4.5.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A bike rental company charges a fee per hour.

The charge, in dollars, is the same each hour.

The ordered pairs (3, 13.50) and (5, 22.50) represent the corresponding hours, x, and cost, y.

Then the linear equation is given as

\begin{aligned} \rm  y - 22.5 &= \rm \dfrac{22.5 - 13.5}{5 - 3} (x-  5)\\\\\rm y - 22.5 &= \rm 4.5x - 22.5\\\\\rm y &= \rm 4.5x \end

Then the rate of change of the function expressed as a unit rate will be

\rm \dfrac{dy}{dx}  = \dfrac{d}{dx} (4.5x )\\\\\dfrac{dy}{dx}  = 4.5

More about the linear system link is given below.
