Answer:
A: 15%
Step-by-step explanation:
First test:
15 ÷ 20 = 0.75
0.75 * 100 = 75%
Second Test:
18 ÷ 20 = 0.9
0.9 * 100 = 90%
90% - 75% = 15%
Answer:
D. (2, 6)
General Formulas and Concepts:
<u>Algebra I</u>
- Solving systems of equations by graphing
Step-by-step explanation:
The solution set of the systems would be where the 2 lines intersect. We see from the graph that our 2 lines intersect at (2, 6). Therefore, our solution set would be D. (2, 6).
Answer:
f^-1 (x) = x/2 - 1
ps the ^ means to the power of so its f to the power of -1.
hope it helps!!
