ANSWER
EXPLANATION
If y varies directly with x, we write the mathematical statement;
When we introduce the constant of proportionality k, then we write the equation,
If y is 2.5 when x is 5,then we have;
The equation of variation then becomes;
when x=14,
Answer:
The answer is D. 14
Step-by-step explanation:
If you were to plug in 14 for x, it would look something like this:
=
Solve 14-4
=
if you were to multiply 5 and 7 by 2, you would get
.
This makes the equation true, because
10/14 does equal itself (10/14)
