Answer:
Option D.
Step-by-step explanation:
The given quadratic equation is
We need to draw the graph of given equation by using graphing calculator as shown below.
From the graph it is clear that the parabola intersect the x-axis at points (-2,0) and (-5,0). So, the x-intercepts are (-2,0) and (-5,0).
Therefore, the correct option is D.
we know there are 5280 feet in 1 mile, and there are 3600 seconds in 1 hour.
4y+2x=14 ==> multiply this 1st equation by (-1) => -4y-2x=-14
Now add it up to the 2nd equation
-4y-2x=-14
2y+2x=10
-------------- And now add them up
-2y +0x=-4
==> -2y=-4==> 2y = 4 & y=2
Last step: plug y into any equation & you will find x=3
Answer:
1.15
Step-by-step explanation:
Multiply each shot by its point value. Then add. Divide this sum by the total number of shots taken.
288*2 + 79*3 + 340*0 = 813
----------------------------------------
288 + 79 + 340 = 707
813 / 707 = 14.992
The weighted average is approximately 1.15 points per shot.
The rational root are x= 7,-3,-6
You can find them by substituting y for 0
