Since its x + 3 we use -3
-3| 2 1 -8 21 (these are the # without the x)
___________________
-6 15 -21
-------------------------------
2 -5 7 0
Drag the 2 down, multiple it by -3 to get -6
1+(-6) = -5. -5 * -3 =15 . 15+(-8) = 7
7*-3 = -21. -21 +21 = 0
Since last # is 0 we have a factor.
factor is 2x^2 -5x -7 (we start with a power 1 less the original.)

Answer:
3 hours
Step-by-step explanation:
290.28-200.22=90.06
90.06/30.02=3
The given point is (0,-12).
It is required to tell whether the point is an x-intercept or a y-intercept.
Recall that the first coordinate of a coordinate point represents the x-coordinate, while the second coordinate represents the y-coordinate.
The x-intercept is the point where the y-coordinate is zero.
The y-intercept is the point where the x-coordinate is zero.
Notice that the given point has an x-coordinate of zero; this means that the given point is a y-intercept.
The point is a y-intercept.
Answer:
The difference in the populations of the cities when t=4 is 25,800.
Step-by-step explanation:
Given equations each of the city:
-150t+50,000
and
50t+75,000
To find the difference between the population when t=4, we first have to solve both equation when t=4.
For both equations, substitute 4 into t:
-150(4) + 50,000 = 49,400
50(4) + 75,000 = 75,200
Now subtract 49,400 from 75,200 and you get 25,800.
The difference in the populations of the cities when t=4 is 25,800.
