5x7=35. Unfortunately I can't show you a model to explain further.
42.8 in
Step-by-step explanation:
Step one:
given data
we are told that the expression for the depth of a lake after x years is given by
Required
The value of y when x= 4
Step two:
substitute the value of x in the expression to get y
After 4 years the depth will increase by 42.8 in
9514 1404 393
Answer:
no, y does not vary directly with x
Step-by-step explanation:
If there is direct variation, the constant of variation can be found as ...
k = y/x
Here, those ratios are ...
y/x = 6/3 = 2
y/x = 18/6 = 3
y/x = 24/8 = 3
The ratio of y to x is NOT A CONSTANT, so <em>there is no direct variation.</em>
