First, I find it helpful to write the function myself.
There is a set fee of $120, and $5 per <em>n</em> badges.
<em />120 + 5<em>n
</em>
This is a basic model. Now we can see if any match.
f(n) = 5<em>n</em> + 120 matches.
Let me know if you found any errors.
Answer:
A Book cover costs = 8.70
A Binder costs = 8.80
8.70 + 8.80 = $17.5
For Brianna
A Book cover costs = 13.75
A Binder costs = 16.75
13.75 + 16.75 = $30.50
For Britney
Answer:
The y-intercept is –2.
The slope is Negative three-fifths
Step-by-step explanation:
A linear function is a function whose graph is a straight line. A linear function can be represented as:
f(x) = y = a + bx
where y is the dependent variable and x is the independent variable. The equation of a linear function in slope intercept form is given as:
y = mx + c
Where m is the slope and c is the y intercept.
Given that:
, and comparing with y = mx + c:
The slope (m) =
The y intercept (c) = -2
Divide by 90%.
x = £55.56
B. (-2,1)
By checking the x coordinates, I saw there was two -2, but the output was different, so one of them had to be taken out to make it a function.
Function: Every input must have one out must.
