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.
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.

1) Is the solution to -2.7 + x= -3.5 positive or
negative.
Answer:
positive because two negatives make a positive and the answer is not positive.
The solution of the expression -2.7 + x =-3.5 is -0.8 and is negative.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given expression is -2.7 + x= -3.5. The value of x will be calculated as,
-2.7 + x =-3.5
x = -3.5 + 2.7
x = -0.8
Therefore, the solution of the expression -2.7 + x =-3.5 is -0.8 and is negative.

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
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.
