D -2, 4 is in the second quadrant because the -x brings it to the left side and the positive 4 puts it in the upper of the left side which is the second quadrant
Answer:
The answer is 2.6 m/s
The speed (v) is distance (d) through time (t).
v = d/t
Step-by-step explanation:
hope this helps :)
If you are looking for the percent off it would be 25% off and if you were looking for the amount off in decimal form it will be 0.25.
Y = -X + 7
Y = .5(X-3)2
Alright check it out. Substitute the Y in the second equation for the first equation so...
-X + 7 = .5(X-3)2
After this, you have to get rid of the .5 and the 2 which is easy peasy because they just cancel out. If you were to multiply by half and then multiply by 2 then you'd be back to where you started. So...
-X + 7 = X - 3
Move the X to combine them on one side, I moved the -X to the opposite side by adding X to each side so you get...
7 = 2X - 3
You then add 3 to both side so...
10 = 2X
Divide by 2
X = 5
So...
Y = -5 + 7
Y = 2
Y = .5(5-3)2
Cancel out the .5 and the 2
Y = 5-3
Y = 2
(5,2) is your answer
