Answer:
16 km is the answer
Step-by-step explanation:
a (Colton to parents' house) = 12 km
b = ?
c (parents' house to grandparents' house) = 20 km
According to the Pythagoras theorem,
a² + b² = c²
12² + b² = 20²
144 + b² = 400
b² = 400 - 144
b² = 256
b = 16
∴ Colton is 16 km away from his grandparents' house.
This downward-opening parabola has its vertex at x = -8, so the function is decreasing on the interval (-8, ∞).
Answer:
-2, -12
-1,-3
0,0
1,-3
2,-12
Step-by-step explanation:
Used algebraic calculator
Slope = (y2 - y1) / (x2 - x1)
(0,4)...x1 = 0 and y1 = 4
(-8,-1)...x2 = -8 and y2 = -1
now we sub and solve
slope = (-1 - 4) / (-8 - 0) = -5/-8 = 5/8 <=
I believe the answer is 24 times
hope this helps!
