2.5 km because 1.5 is half of 3 and half of 5 is 2.5
When x=0 y=50 when y=0 x=+\-5. -x^2 makes the parabola open downward y(x)=2x^2+50;y(3)=2*9+50=32
The answers are:
• A
• C
• E
Answer:
19) -3/-4
20)2/1
Step-by-step explanation:
(-1,5) = (x1,y1)
(3,13) = (x2,y2)
slope(m) = (y2-y1)/(x2-x1)
= 2
by using slope point form
y-y1 = m (x-x1)
y-5 = 2(x+1)
2x-y+7=0
