A = P(1 + rt)
1565 = 625(1 + (0.047)(t))
2.504 = 1 + 0.047t
1.504 = 0.047t
t = 32
I hope this is correct! (Sorry I haven't done simple interest in a while.)
Hello!
First off, when it is a < or > symbol, the circle is open.
When it is a ≤ or ≥ symbol, the circle is closed.
Therefore, the correct answer is C, because |x| can be -5 or 5, the graphed circles are closed, and the solutions are less than, not greater than -5 and 5.
X = -5
Multiply by -1 on both sides
-1(x) = -1(-5)
Simplify
-x = 5
Answer:
A
Step-by-step explanation:
The student must have thought that every single arrowhead is a line of symmetry, so since there are 10 arrowheads, there must be 10 lines of symmetry. This is incorrect because if you look closely at the diagram, each line has 2 arrowheads, so the student is overcounting by a factor of 2. They should have just counted the number of lines, not arrowheads. Therefore, there must be 10/2 = 5 lines of symmetry, not 10. Hope this helps!
