Step-by-step explanation:
Note that the difference between consecutive terms is - 8
To obtain the next term in the sequence subtract 8 from the previous term.
next term = 56 - 8 = 48
The sequence is 72, 64, 56, 48

Answer:
y + 2 = -2(x - 3)^2
Step-by-step explanation:
We can see immediately that the vertex is at (3, -2).
The vertex form of the equation of a parabola is
y - k = a(x - h)^2.
If the parabola opened upward, the equation would be y + 2 = 2(x - 3)^2. But seeing that this particular parabola opens downward, the equation is
y + 2 = -2(x - 3)^2.
Check: Does the point (2, -4) satisfy this equation?
-4 + 2 = -2(2 - 3)^2 becomes -2 = -2(-1)^2, which is true.
Answer:
x = 5
Step-by-step explanation:
25 = 6x - 5 (add 5 on both sides)
+5 +5
30 = 6x (divide by 6 on both sides)
5 = x
Hope this helps ya!!
The answer is 720 mph, since we make time the x and distance y. We use the slope formula (y2 - y1)/(x2 - x1)
(179-23)/(17-4)
156 miles/13 mins
12 miles per min
Since the answer is in hours instead of minutes, we multiply 12 by 60 to get 720 mph
