1 penny each day = 7 pennies each week
total pennies = 161
divide 161 by 7 = 23 weeks
The general form for a sine function is: y = a sin(b[x + c]) + d
The amplitude is given by a, so a = 1.
The period is given by 2*pi/b, so 2*pi/b = pi/2, and b = 4.
The variable c gives the horizontal shift, of which there is none, so c = 0.
Finally, the vertical shift of 3 units means that d = 3.
So the equation is:
y = sin(4x) + 3
Answer: Substitution
Step-by-step explanation: I think that because you have the equations already, you just have to solve for a variable using substitution. Do this by substituting one of the variables with another number. For example, make x=2 in both equations. Now you are free to solve for y and get your answer.
y=-2.5(2)+16
y=11
y=-1.5(2)+12
y=9
You can substitute in any number that makes it easy for you. Also, if you want x, you can substitute y. I'm really, really sorry if that is not helpful, I just told you what I know!
