Answer:
<h2><em><u>5</u></em></h2>
Step-by-step explanation:
<h3><em><u>Given</u></em><em><u> </u></em><em><u>Question</u></em><em><u>:</u></em></h3>
<em><u>Given</u></em><em><u> </u></em><em><u>values</u></em><em><u> </u></em><em><u>-</u></em>
r = 4 , s = 1
<em><u>Therefore</u></em><em><u> </u></em><em><u>putting</u></em><em><u> </u></em><em><u>their</u></em><em><u> </u></em><em><u>values</u></em><em><u> </u></em><em><u>in</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>question</u></em><em><u>, </u></em>
= 4 + 1
= <em><u>5 (Ans)</u></em>
Answer:
Given that Angelo spends the same amount every day from the amount in
the lunch card, the function of the amount remaining is a linear function.
The constant rate of change of the function is; -5.25
The two ordered pairs used to find the constant rate of change are; (1, 44.75) and (2, 39.5)
Reasons:
The amount Angelo's mother put on the lunch card = $50
A possible table of values to the question is presented as follows;
Required:
The constant rate of the function that gives the amount remaining from the
amount Angelo's mother put on his lunch card.
Solution:
The two ordered pairs that can be used to find the slope or constant rate of change are;
(x₁, y₁) = (1, 44.75), and (x₂, y₂) = (2, 39.5)
With the above two ordered pairs, we have the constant rate of change of the function given as follows;
The constant rate of change for the function that gives the amount remaining in the lunch card is; -5.25
