Y² - 12y + 32

The middle term must be written in such a way that the sum of two numbers is -12y and the product is 32y²

The two such numbers are -4y and -8y

So, we can write:

y² - 4y - 8y + 32

= y(y - 4) - 8(y - 4)

= (y - 4)(y - 8)

So, option B gives the correct answer

Finding the inverse function of f(x) = 5\sqrt{x + 3} - 2, it is best described by graph B.

<h3>How to find the inverse of a function?</h3>

Supposing we have a function y = f(x), to find the inverse, we exchange x and y, and isolate y.

In this problem, the function is:

f(x) = 5\sqrt{x + 3} - 2

y = 5\sqrt{x + 3} - 2

Exchanging x and y:

x = 5\sqrt{y + 3} - 2

Working through the function to isolate y:

5\sqrt{y + 3} = x + 2

\sqrt{y + 3} = \frac{x + 2}{5}

(\sqrt{y + 3})^2 = \left(\frac{x + 2}{5}\right)^2

y + 3 = \frac{(x + 2)^2}{25}

y = \frac{(x + 2)^2}{25} - 3

f^{-1}(x) = \frac{(x + 2)^2}{25} - 3

Which is best represented by graph B.

Is it possible that for every right triangle, it has two complementary angles?
Montano1993 [528]
Yes, every right triangle has two complementary angles.

This is because you know that the interior angles of a triangle have to add up to 180 degrees.

A right angle is 90 degrees, so the remaining two angles have to add up to (180-90) degrees, or 90 degrees.

Two angles whose sum is 90 degrees are complementary.
