Suppose that y varies directly with x and y =10 when x = 20. What is y when x=15
Vanyuwa [196]

y=13.34 when x=15

Step-by-step explanation:

We are given that x varies directly with y i.e y ∝ x

We know that: y ∝ x then

y= k/x

where k is constant.

So, if y=10 and x=20 we can find k

y=\frac{k}{x}\\10=\frac{k}{20}\\ k=10*20\\k=200

Now, we need to find y when x=15

We know that k = 200,

So, y=\frac{k}{x}\\y=\frac{200}{15}\\y=13.34\\

So, y=13.34 when x=15

Please help me answer this question. Explain if possible.
ExtremeBDS [4]
The functions have the same initial value is correct

"The functions have the same rate of change" is wrong because as we can see, the table goes up by 10, however, the graph goes up by 15

"Both functions are the same" is also wrong, we already proved they have a different slope, how could they possibly be the same?

"The rate of change for Tour 1 is greater" is also wrong because tour 2 goes by 15, which is greater than 10.

"The functions have the same initial value is correct because as we can see on the graph(tour 2), the y-intercept is 35, using the slope on the tab;e(tour 1) we can calculate that when x is 0, the y-value is 35, which means both of the tours has a y-intercept of 35, therefore, this is the correct choice
