Answer:
The equation representing Total money spend being as a member is
Step-by-step explanation:
Given:
Memberships charges = $60
Cost of 1 book = $7.60
Let number of books be 'b'.
We need to find Total money 'm' spend yearly on buying books after becoming member.
Now we know that 1 book is free for a member.
Total money spend 'm' will be equal to Sum Memberships charges and Cost of 1 book multiplied by number of books bought yearly minus 1.
Framing in equation form we get;
Hence The equation representing Total money spend being as a member is
Answer:
(3, 0) and (5, 0)
Step-by-step explanation:
we have
we know that
The x-intercepts are the values of x when the value of y is equal to zero
so
For y=0
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
so
x=3, x=5
therefore
The x-intercepts are (3,0) and (5,0)
Answer:
Part A) The slope is
Part B) The equation of the line is
Step-by-step explanation:
Part A) What is the slope of the graph?
we know that
The formula to calculate the slope between two points is equal to
Looking at the graph it takes any two points
(-2,0) and (0,-1)
substitute the values in the formula
Part B) Write an equation for the line
we know that
The equation of the line in slope intercept form is
where
m is the slope
b is the y-coordinate of the y-intercept
we have
----> the y-intercept is the point (0,-1)
substitute
