Answer:
80 in each group
Step-by-step explanation:
554+47 = 601 (47 last month)
601+39 = 640 (39 this month)
640 / 8 = 80 (8 equal groups)
Answer:
The general rate of change can be found by using the difference quotient formula. To find the average rate of change over an interval, enter a function with an interval:
f
(
x
)
= x
^2
, [
2
,
3
]
The rate of Change is 2
Step-by-step explanation:
Answer:
5/1
Step-by-step explanation:
you dont have to make it hard just estimate.
9/4 is about 2 1/9
5/4 is 1.2
5/1 is 5
3/7 is a little more than one half
10/9 is a little more than one
5/1 over one is the greatest and there is no confusion between the ones that are hard to calculate.
Answer:
y = (x - 3)² + 6
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
Using the method of completing the square
y = x² - 6x + 15
add/subtract ( half the coefficient of the x- term )² to x² - 6x
y = x² + 2(- 3)x + 9 - 9 + 15
y = (x - 3)² - 9 + 15
y = (x - 3)² + 6 ← in vertex form
