They are all perfect squares because if you took the square root of them you will get a single number. Like the square root of 25 is 5 bc 5(5) is 25
<span>16 is 4 bc 4(4) is 16 </span>
<span>9 is 3 bc 3(3) is 9 </span>
<span>1 is 1 bc 1(1) is 1 </span>
<span>& so on & so forth</span>
Answer:
h(x) = x - 2
Step-by-step explanation:
h(x) = -2x - 4 -(-3x - 2)
-2x - 4 + 3x + 2
x - 2
Answer:
y=1/2x-3
Step-by-step explanation:
y intercept, -3
slope 1/2
Answer:
- geometric sequence with initial value 20 and common ratio 1/2
- average rate of change on [1, 3] = -7.5
Step-by-step explanation:
(a) The given points have sequential values of x and values of y that are each 1/2 the value before. The common ratio tells us the sequence is a geometric sequence.
(b) The first given point is (2, 10), so extrapolating backward, we determine the previous point to be ...
... (2-1, 10/(1/2)) = (1, 20)
Thus, we have enough information to determine the average slope between n=1 and n=3.
... (difference in y)/(difference in n) = (5 -20)/(3 -1) = -15/2 = -7.5
