Answer:

x = 5

Step-by-step explanation:

x^2/(x + 5) = 25/(x+5) Subtract the right side from both sides.

x^2/(x + 5) - 25/(x + 5) = 0

x^2 - 25

======= = 0

x + 5

(x + 5)(x - 5)

============= = 0

(x + 5)

Cancel x + 5 in the numerator and denominator.

x - 5 = 0

x = + 5

Does it check?

x^2/(x + 5) = 25/(x + 5)

x = 5

5^2/(10) = 25/10

25/10 = 25/10 Yes it checks.

The graph shows a 90° rotation. The matrix M such that, for any point (x, y), M(x, y) = (x', y') is

guapka [62]

Answer:

A) $\left[\begin{array}{cc}0&-1\\1&0\end{array}\right]$

Step-by-step explanation:

The rotation matrix for a clockwise rotation through angle θ is given by ...

$M=\left[\begin{array}{cc}\cos{(\theta)}&-\sin{(\theta)}\\\sin{(\theta)}&\cos{(\theta)}\end{array}\right]$

When θ = 90°, the matrix becomes the one in choice A).
