Answer:
(a) The y-intercepts of both functions are the same, 0. However, the rate of change for the school library is 0.25, while the rate of change for the city library is 0.35.
(b) The 3-day late fee at the school library is $0.75 and the 3-day late fee at the city library is $1.05.
Step-by-step explanation:
The functions represented in the question are linear, which means that they have a consistent rate of change over time. In this example, it means that for every day, the late fee charged by each library is the same. At the school library, the rate of change is 0.25, which means for each day the book is late, the school charges a fee of $0.25. At the city library, the table shows that for each day the book is late, the city charges a fee of $0.35. So, the city library is more expensive. Y-intercept refers to the initial cost, or how much do the libraries charge if the book is not late, or turned in on time. In this case, neither library charges a fee for books turned in on time, so both would have a y-intercept of 0.
Answer:
(4b-9) (4b+9)
Step-by-step explanation:
16b^2 – 81
This is the difference of squares
(a^2 -c^2) = (a-c) (a+c)
a^2 = 16b^2 so a= 4b
c^2 = 81 so c = 9
(16b^2 – 81) = (4b-9) (4b+9)
Answer:
-2
Step-by-step explanation: All you have to do is insert the s and t value they gave you into the equation.
2s + 4t = ?
2(3) + 4(-2) = ?
6 + (-8) = ?
= -2
Slope intercept form is y = mx + b
First step: Pick two coordinates from the graph. I chose: (0, -3) and (-2, 5).
Second step: Now use the formula y2-y1 over x2-x1 to calculate the slope. It should look like this: 5 - - 3 over -2 - 0 = -8/2. Simplify it to -4.
Third step: Write this in slope intercept form.
—> FINAL answer: y = -4x - 3.
Answer:
<em>Well, The best answer will be is </em><em>y = 2. Good Luck!</em>
