Answer:
Each person will pay $9.78
Step-by-step explanation:
Given that:
Amount of bill = $34
Tip = 15%
Amount of tip =
Amount of tip = 0.15 * 34
Amount of tip = $5.10
Amount after bill = 34 + 5.10 = $39.10
Number of people = William + three friends = 4
Per person share =
Per person share = $9.775
Rounded to two decimal places
Per person share = $9.78
Hence,
Each person will pay $9.78
The slope of a line is given by the ratio of the rise to the run of the line.
The value of, y is <u>4</u>
Reasons:
The given points on the line are; (-4, y), and (5, 7)
The slope of the line, =
Required:
To find the value of <em>y</em>
<em />
Solution:
The formula for the slope is given as follows;
Where;
(x₁, y₁) = (-4, y)
(x₂, y₂) = (5, 7)
Which gives;
3·(7 - y) = 1·(5 + 4) = 9
21 - 3·y = 9
3·y = 21 - 9 = 12
The value of, y = <u>4</u>
