Jocelyn is saving money. She started with $0, and after 8 weeks, she had $60. Jocelyn is not sure exactly how much money she saved each week, but she assumes that she saved money at a constant rate from when she started saving money through Week 8.
Answers
Answer:
We know that:
Jocelyn started with $0, this is represented with the point (0, $0)
After 8 weeks, she had $60, this is represented with the point (8, $60)
Jocelyn assumes that she saved money at a constant rate, so we can represent this with a linear relationship.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
In our case, y is the amount of money that she has saved, x is the number of weeks since she started saving, the slope is the amount of money that she saves each week, and the y-intercept is the initial amount of money that she had saved.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
In this case, our two points are:
(0, $0) and (8, $60), then the slope will be:
a = ($60 - $0)/(8 - 0) = $60/8 = $7.5
our equation is:
y = $7.5*x + b
To find the value of b, just replace both values in one of the points in the equation, for example, the point (0, $0)
$0 = $7.5*0 + b
$0 = b
Then our equation is:
y = $7.5*x for 0 ≥ x ≥ 8
Where i added a restriction in the domain because this is described only for the first 8 weeks after she started saving money.

A rectangular yard has a width that is 10 feet longer than the width . If the the area of the yard is 600 squared feet , find the dimension of the yard
Answers
Answer:
length = 30 feet and width = 20 feet
Step-by-step explanation:
Let l is length and b is width of a rectangular yard. The area of a rectangle is given by :
A = lb ..(1)
A rectangular yard has a length that is 10 feet longer than the width.
length, l = 10+b ...(2)
ATQ,
Put the value of l in equation (1),
[tex](10+b)b=600\\\\10b+b^2=600\\\\b^2+10b-600=0\\\\b^2+30b-20b-600=0\\\\b(b+30)-20(b+30)=0\\\\(b+30)(b-20)=0\\\\b=-30\ \text{feet}\ \text{and}\ b=20\ \text{feet}[/tex]
Width can't be negative. The width is 20 feet.
Put the value of b is equation (2),
l = 10+20
l = 30 feet
Hence, the length and width are 30 feet and 20 feet.
