Y is a vertical axis
x is a horizontal axis
when drawing a line, the line drawn to them is perpendicular so lines only touching the x axis are vertical and lines touching only the y axis are horizontal
the
a vertical line is x=value
the only thing that works is x=12
Answer:
x=1,2
Step-by-step explanation:
x^2-3x+2=0
(x-1)(x-2)
x-1=0
x-2=0
x=1,2
Based on the numbers we have we can assume that she saves 3 times more each week than the last (1*3=3, 3*3=9).
Following this trend we would multiply the amount she saved the third week ($9) by 3 to get $27 for the fourth week.
Then, we would multiply the amount she saved the fourth week ($27) by 3 to get $81 for the fifth week.
Finally, to figure out how much she saved in the 5 weeks, we need to add each value up to get 1+3+9+27+81= $121 saved in 5 weeks
In order to solve this, we need to figure out how much ONE student spends.
![\frac{12dollars}{4students} = 3](https://tex.z-dn.net/?f=%20%5Cfrac%7B12dollars%7D%7B4students%7D%20%3D%203%20)
dollars per student.
If 10 student spent for lunch, we just have to multiply our number by how much each student spends.
