Y = x and y =x^2 - 2

Mathematics
1 answer:
maxonik [38]4 years ago
6 0

Answer:

  (-1, -1) and (2, 2)

Step-by-step explanation:

Substitute for y in the first equation and solve the quadratic.

  x = x^2 -2

  x^2 -x -2 = 0  . . . . subtract x

  (x -2)(x +1) = 0 . . . .factor

Solutions are the values of x that make these factors be zero:

  x = 2, x = -1

Since y=x, the solutions are ...

  (x, y) = (-1, -1) and (2, 2)

The angle ____ is the smallest positive coterminal angle with 915 degrees
olga55 [171]

Step-by-step explanation:

We can find the coterminal angle by simply adding or subtracting 360° to each angle. In this problem, we need to find the smallest positive coterminal angle with 915 degrees.

It can be calculated by adding or subtracting 360° to the given angle. For positive coterminal angle subtract 360° from 915°

915-360 = 555

555-360 = 195

The positive coterminal angles: 195°, 555°, 915°, 1275°, 1635°...

The negative coterminal angles: -165°, -525°, -885°, -1245°...

Hence, the angle<u> </u><em><u>195°</u></em> is the smallest positive coterminal angle with 915 degrees
