Write an appropriate direct variation equation if y = 18 when x = 2

Sergeu [11.5K]

Answer:

$y=9x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In this problem we have

y=18 when x=2

Find the value of the constant of proportionality k

$k=\frac{y}{x}$ ----> $k=\frac{18}{2}=9$

therefore

The equation is equal to

$y=9x$

Answer:

The hypotenuse is square root of 65

Step-by-step explanation:

a^2 + b^2 = c^2

legs of the right triangle are a and b. Just substitute 4 for a and 7 for b and solve.

4^2+7^2=16+49=65

c^2=65

Find the square root of both sides to get

c=the square root of 65
