Answer:
y = 6
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 9, then
k = = = , thus
y = x ← equation of variation
When x = 18, then
y = × 18 = = 6
A. X^2-10x. =-8
To complete the square you get half of -10 and then square that number half of -10 is -5 and -5 times -5 equals positive 25 that would you add to each side
x^2-10x+25=-8+25
17
The correct matches are as follows:
quartile
10.5
<span>median
41
third quartile
</span>38.5<span>
the difference of the largest value and the median
49-41 = 8
Hope this answers the question. Have a nice day. Feel free to ask more question.
