Ratio problem
1 cm = 120 km
------- = --------
x 463
120x = 463
x = 23.15 = 23.2
Let there exists a point (x, y) on the given line.
Slope of all points must be same, as they lie on the same line.
=> (y - 1)/(x - 2) = (4 - 1)/(-4 - 2)
=> (y - 1)/(x - 2) = - 1/2
=> y - 1 = (-½) (x - 2)
Option 1 is the correct option
Answer:
b < 50. The solution has infinite solutions because any number smaller than 50 would work, and their are infinite numbers smaller than 50.
Step-by-step explanation:
Answer:
1. t=240
2.t/3=(t/4)+20
Step-by-step explanation:
To be a function each different x value would have a different Y value.
First one is a function, there are no repeated Y values.
The second one is a function.
Third one is not a function because it has two identical Y values with different x values.
The fourth one is a function.
