Answer:
y = -
x + 1
Step-by-step explanation:
The equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept. I will be calculating the slope using the points (3, 0) and (0, 1).
Slope = ![\frac{0-1}{3-0}](https://tex.z-dn.net/?f=%5Cfrac%7B0-1%7D%7B3-0%7D)
= ![\frac{-1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7B3%7D)
Thus, the slope of the line is -
.
Based on the graph, the y-intercept is 1.
Thus, the equation of the line is: y = -
x + 1.
Answer:
-1/5
Step-by-step explanation:
![\frac{2}{3}+\frac{-13}{15} \\=\frac{10}{15} +\frac{-13}{15}\\ =\frac{-3}{15} \\=\frac{-1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%2B%5Cfrac%7B-13%7D%7B15%7D%20%20%5C%5C%3D%5Cfrac%7B10%7D%7B15%7D%20%2B%5Cfrac%7B-13%7D%7B15%7D%5C%5C%20%3D%5Cfrac%7B-3%7D%7B15%7D%20%5C%5C%3D%5Cfrac%7B-1%7D%7B5%7D)
64% on sale means ( 100-64 = 36) 36% are full price
125 * 0.36 = 45 CDs are full price
100= 10^2.
The missing exponent is 2~
