You solve this through error and trial.
The is to get two matching numbers at both sides.
<u>X 2x + 3 = 3 (x + 1) - x </u><u> </u><u> </u><u> </u><u>Answer</u>
0 2(0) + 3 = 3 (0 + 1) - 0 3 = 3
1 2(1) + 3 = 3 (1 + 1) - 1 5 = 5
You do this all the way to ten. So far, we know x = 0 and x = 1 is correct
This looks like a parabola so:
y=x^2 - 20x + 15 --> x^2 - 20x +15=y
(x^2 -20x)=y - 15 --> (x - 10)^2=y - 15 +100 ( used complete the square)
(x - 10)^2=y + 85
Answer:
P2+p+4p+4
p(p+1)+4(p+1)
(p+4)(p+1)
p=-4 and p=-1

After simplifying you get (-9,10)
In baseball the infield is a square, 90 feet on a side. The catcher, who plays behind home plate, has to throw the ball to second second base if a runner is trying to steal. How far is it from home plate to second base?
