Answer:
Step-by-step explanation:
step 1
Find the slope of the line parallel to the given line
we know that
If two lines are parallel, then their slopes are equal
The equation of the given line is 
The slope of the given line is 
so
The slope of the line parallel to the given line is also
step 2
Find the equation of the line parallel to the given line
The equation of the line in point slope form is
we have
substitute
step 3
Convert to slope intercept form
Isolate the variable y
40 + 5x = y
X is how many weeks she saves
Y is the total savings after 12 weeks
Plug in 12 into the x
40+5(12) = y
40 + 60 = y
100 = y
She will have saved $100 after 12 weeks
Im not sure but I think you add
5000 meters in 5 kilometers I'm pretty sure
Negative numbers aren't in a solution set because in equations and inequalities you have to multiply and divide and a positive number divided by a negative number will be a negative number. Positive divided by positive will be positive. Negative divided by negative will be positive. So that's why negative numbers aren't a solution to any set or equation.
hope this helps
