Answer:

The third one

Step-by-step explanation:

All show complementary angles ( angles that add up to 90 degrees ) except for the third one

First one: shows a square within the two angles which indicates that the angles form a right angle ( 90 degree angle ) meaning that they are complementary angles

Second: the angles add up to equal 90 ( 50 + 40 = 90 ) hence they are complementary angles

Third one: the angles form a straight line. Angles that form a straight line add up to equal 180 and are known as supplementary angles

Fourth: the angles shown add up to 90 ( 65 + 25 = 90) hence they are complementary angles

All are complementary but the third one

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

4x + 5y = -12

-2x + 3y = -16

<u>Step 2: Rewrite Systems</u>

-2x + 3y = -16

  1. Multiply everything by 2:                    -4x + 6y = -32

<u>Step 3: Redefine Systems</u>

4x + 5y = -12

-4x + 6y = -32

<u>Step 4: Solve for </u><em><u>y</u></em>

<em>Elimination</em>

  1. Combine 2 equations:                    11y = -44
  2. Divide 17 on both sides:                  y = -4
