Answer:
8
Step-by-step explanation:
<u> 4 x² = 64</u>
Divide each side by 4 : x² = 16
Take the square root
of each side: x = √16
x = <em>+ 4</em>
and
x = <em>- 4</em> .
Answer: 1/4
Step-by-step explanation:
3/4-1/2=1/4
Answer:

Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition
x = 2 when y = 2
k = yx = 2 × 2 = 4, hence
y =
← equation of variation
Answer:
4
Step-by-step explanation:
From the graph we can read off the interval over which the graph repeats itself. If we chose to begin at (0,0), the graph would repeat itself beginning at (4,0). Thus, the period is 4.
