80 km = 80000 m
5 saatte = 300 dk’dir
80000m/300 dk’dir = 266.666667 m/dk’dir

Answer:
linear with a common first difference of 2
Step-by-step explanation:
If this is linear, the common first difference, or slope, will be the same throughout the entire table.
The formula for slope is

For the first set of points, we have:
m=(0--2)/(-2--3) = (0+2)/(-2+3) = 2/1 = 2
For the second set of points, we have:
m = (4-0)/(0--2) = 4/(0+2) = 4/2 = 2
For the third set of points, we have:
m = (12-4)/(4-0) = 8/4 = 2
The rate of change, or slope, is constant; this makes the function a linear function with a common first difference of 2
Hope it helps
Answer:
We have the following theorem:
If <em>f </em>is a quadratic function of the form and , then the function <em>f </em>has two x-intercepts.
(a)
For this function a = -8 and c = -2, then is greater than zero. Therefore, we cannot conclude anything.
(b)
For this function a = -8 and we don't know the value of c. Therefore, we cannot conclude anything.
(c)
For this function a = 8 and c = -7, then is less than zero. Therefore, we can conclude that the function <em>k </em>has two x-intercepts.
(d)
For this function a = and c = 210, then is less than zero. Therefore, we can conclude that the function <em>k </em>has two x-intercepts.
(e)
For this function a = 4 and c = 7, then is greater than zero. Therefore, we cannot conclude anything.
(f)
We cannot conclude anything because this is not a quadratic function.
-3/4 > = w - 1....add 1 to both sides
-3/4 + 1 > = w
-3/4 + 4/4 > = w
1/4 > = w
Use this formula, it’s called distance formula
