Solve the system, enter the smallest x coordinate first

The solutions to the system of equations are given as follows: (1, -3) and (-4,2).

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

The equations are given as follows:

  • (x + 3)² + (y + 2)² = 17.
  • x + y = -2.

From the second equation:

y = -2 - x.

Replacing in the first:

(x + 3)² + (y + 2)² = 17.

(x + 3)² + (-2 - x + 2)² = 17

x² + 6x + 9 + x² = 17

2x² + 6x - 8 = 0

2(x² + 3x - 4) = 0

2(x + 4)(x - 1) = 0.

Then the solutions for x are:

  • x + 4 = 0 -> x = -4.
  • x - 1 = 0 -> x = 1.

The solutions for y are:

  • When x = 1, y = -2 - 1 = -3.
  • When x = -4, y = -2 -(-4) = 2.

Hence the solutions are:

(1, -3) and (-4,2).

Need help plz?????????!!!!!!
Llana [10]

Answer:

93°

Step-by-step explanation:

By exterior angle theorem:

(4x + 9)° = 2x° + (3x - 12)°

(4x + 9)° = (2x + 3x - 12)°

(4x + 9)° = (5x - 12)°

4x + 9 = 5x - 12

4x - 5x = - 12 - 9

-x = - 21

x = 21

Measure of exterior angle

= (4x + 9)°

= (4*21 + 9)°

= (84 + 9)°

= 93°
