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? 06
18
30
0 36

n = 30

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 180 when x = n, then

180 = kn ( divide both sides by n )

k =

y = x ← equation of variation

y = n when x = 5, thus

n = × 5 = ( multiply both sides by n )

n² = 900 ( take the square root of both sides )

n = = 30

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
