If Y Varies Directly As X, And Y Is 180 When X Is N And Y ~ OnNews

If y varies directly as x, and y is 180 when x is n and y is n when x is 5, what is the value of n? A.6 B.18 C.30 D.36 - 8138283If y varies directly as x and y is 180 when x is n and y is n when x is 5, what is the value of n? - 2496520The following practice problem has been generated for you: y varies directly as x, and y = 20 when x = 29, solve for y when x = 20y = kx. y = (180/n)x. y = 180x/n. Then you are told that y = n when x = 5. Substitute and simplify to see what we have: n = 180(5)/n. n = 900/n. You are asked to find the value of "n". We can solve for that. Multiply both sides by "n" then get the square root of both sides: n² = 900. n = ±30. There are two possible outcomes for n. Let's testN is 30) When y = 180, x = n. If we write the value of y on the top and x on the bottom, one side of the proportion is: 180 n 2. When y = n, x = 5. So the other side of the proportion would be: 180 n = n 5 3. Cross multiply. 180 (5) = n (n) 900 = n 2 4. Take the square root of both sides to find n. √ 900 = √ n 2 30 = n That's your answer

If y varies directly as x and y is 180 when x is n and y

y = x. Example 2: If y varies directly as x, and the constant of variation is k = , what is y when x = 9? y = x = (9) = 15. As previously stated, k is constant for every point; i.e., the ratio between the y-coordinate of a point and the x-coordinate of a point is constant. Thus, given any two points (x 1, y 1) and (x 2, y 2) that satisfy theUse this free online constant of variation calculator to generate equation based on the given x and y values. This is also called as direct proportion and constant of variation (k). This online direct variation calculator relates two variables in such a way that their values always have a constant ratio, which directly vary.Y varies directly as x.

Let's write a percentage to constitute this downside!

1. When #y = 180#, #x = n#. If we write the value of y on the top and x on the bottom, one side of the proportion is:

#180/n#

2. When #y = n#, #x = 5#. So the other side of the proportion would be:

#180/n = n/5#

3. Cross multiply.

#180(5) = n(n)##900 = n^2#

4. Take the sq. root of all sides to seek out #n#.

#sqrt(900) = sqrt(n^2)#

#30 = n#

That's your solution!
