Answer:
15%
Step-by-step explanation:
The quantities must be in the same units
Using the conversion
I hour = 60 minutes, then
3 hours 20 minutes = ( 3 × 60) + 20 = 180 + 20 = 200 minutes.
Thus
× 100% =
= 15%
Answer:
C. (60, 25) and (240, 150)
Step-by-step explanation:
The only option that contains two points that can be found on the graph showing the relationship between number of miles and cost of trip is option C, which are (60, 25) and (240, 150).
From the graph, we can see that when x = 60, y = 25, and
When x = 240, y = 150.
Answer:
y = 1x - 1
Step-by-step explanation:
![\frac{y2-y1}{x2-x1}\\\frac{1-(-4)}{2-(-3)}\\\frac{1+4}{2+3}\\\frac{5}{5}=1\\y=1x+b\\1=1(2)+b\\1 = 2 + b\\-1 = b\\y = 1x-1](https://tex.z-dn.net/?f=%5Cfrac%7By2-y1%7D%7Bx2-x1%7D%5C%5C%5Cfrac%7B1-%28-4%29%7D%7B2-%28-3%29%7D%5C%5C%5Cfrac%7B1%2B4%7D%7B2%2B3%7D%5C%5C%5Cfrac%7B5%7D%7B5%7D%3D1%5C%5Cy%3D1x%2Bb%5C%5C1%3D1%282%29%2Bb%5C%5C1%20%3D%202%20%2B%20b%5C%5C-1%20%3D%20b%5C%5Cy%20%3D%201x-1)
This is a quadratic formula, which is (-b+-sqrt(b^2-4ac))/2a.
Parabolic graphs are quadratic formulas.
