First one simplifies to 2x + 6 = 2x + 7 which can't be true so this one has No Solution.
Same applies to the second equation ( 5x + 15 = 5x - 15) No solution
also the last one has no solution because it simplifies to 4x + 20 = 4x + 19
Answer:
y-intercept = 7
Step-by-step explanation:
The y-intercept is also the starting point
Max:
Min:
Amplitude: 3
Horizontal Shift: 0
Vertical Shift: -2
I'm not sure on the max and min, but here is everything else. ^_^
If the area for a circle is

, you can write it in terms of its diameter like this:
