Is y 4x 9 a direct variation?
no. It must be an equation of the form y = kx.
What are the values of k when kx plus y equals 4 is tangent to the curve y equals x squared plus 8 showing work?
If: kx+y = 4 and y = x^2+8 Then: x^2+8 = 4-kx => x^2+4+kx = 0 For the line to be tangent to the curve the discriminant of b^2-4(ac) must = 0 So: k^2-4(1*4) = 0 => k^2 -16 = 0 => k^2 = 16 => k = +/- 4 Therefore: y+4x = 4 and y-4x = 4 are tangents to the curve y = x^2+8
How do you find constant of proportionality using equation?
If the equation is y = kx then the constant of proportionality is k.
Why does the graph of an equation expressing direct variation always pass through the origin?
For a direct variation, y=kx where k is the constant of variation if x =0 then y=0 and the graph of y=kx passes through the origin. -Indiana Prentice Hall Algebra 2 Text Book.
What do you know about direct proportion and inverse proportion?
direct proportion: y=kx inverse proportion: y=k/x
What goes faster KX 85 dirt bike or KX 100 dirt bike?
kx 100 is faster on bottom end speed kx 85 is faster on top end speed so they are about equal to some extent. ;)
What is faster a kx 60 or a yz 85?
believe it or not, the kx 60 is faster a cause of it having a motor too powerful for the small, light frame, so yes, the kx 60 is faster than the yz 85
What is faster crf150r or a kawasaki kx 85?
The kx 85 is over all faster......but the 150r would give it a run for its money
Witch is faster a KX85 or a KLX140?
kx 85
Is a kx 85 better than a crf 150r?
a crf150r is like a rocket to a kx85 a crf150r will eat a kx 85 for breakfast!!! there both fast but i have trouble with the kx and no trouble with 150!!! So overall a crf150r runs better and is faster!!!
Should I get a KX 100 or a KTM 105 and is a KTM 105 that much better than a KTM 85?
Kx 100s are easy and cheep to fix. Ktms are great motorcycles but they can be more expensive to repair. Kx 100
Is a yz 85 faster than a sx 85?
yes, top speed of a yz 85 is 140km/h top speed of the ktm 85sx is 104km/h, however the ktm is better in performance and got softer stocked suspension
How fast is a kx 85?
A KX 85 STOCK WILL TOP OUT AT ABOUT 68-70MPH. well mine will top out at 85mph cause its no normal kx 85
Is a 1994 kx 250 faster than a 1993 kx 250?
no 93 kx 250 had more performance parts on them
How much is a kawasaki kx 100 worth?
more then a 85 probably more than $1000 if its like an 04 or newer its over $1500
What is faster kx 80 or cr 80?
the kx is faster
How old can you ride a kx 85?
you can ride a kx 85 any age there is no lmit :D
