What is the value of x?

Lerok [7]

Answer:

3√2

Step-by-step explanation:

The hypotenuse of an isosceles right triangle is √2 times the side length.

x = 3√2

_____

All these triangles are similar, so the ratio of hypotenuse to leg is the same for all.

hypotenuse/leg = x/3 = (3+3)/x

x² = 3·6 = 3²·2 . . . . cross multiply (identify square factors)

x = 3√2 . . . . . take the square root

Which function represents a proportional relationship? A) f(x) = 3x 4 B) f(x) = 3 4x C) f(x) = 3x 4 + 3 4 D) f(x) = 3 4x + 3 4

densk [106]

Answer: OPTION B

Step-by-step explanation:

The equation of a line that passes through the origin is the following:

$y=mx$

Where "m" is the slope of the line.

By definition, Proportional relationships have the following form:

$y=kx$

Where "k" is the Constant of proportionality.

Then, as you can notice, if you graph a Proportional relationship you will get a line that passes through the origin.

Therefore, based on the explained above, you can conclude that the option that shows a function that represents a Proportional relationship is the Option B.

Then, this is:

$f(x)=\frac{3}{4}x$
