X + y - z = 9
3x - y + z = -13
____________(+)___
4x =  -4 => x = -1 => y - z = 10;
But, x - 2y + 4z = -1 => -2y + 4z = 0 => -y + 2z = 0;

 y  -  z = 10
-y + 2z = 0
_________(+)__
/       z = 10 =>   y = 20 .

A. There is one solution. The solution is ( - 1, 20, 10 ).

Extra P./Geometry <br> Help quick! Thanks In Advance :)

The measure of angle C is 89 degrees.

<u>Step-by-step explanation:</u>

The given polygon ABCD is a quadrilateral.

<u>The property of a quadrilateral :</u>

The sum of the consecutive angles add to 180°.

In this quadrilateral, the angles B and C are consecutive angles. So, the sum of angle B and angle C is equal to 180 degree.

Given that,

  • The measure of angle B = 2x+3
  • The measure of angle C = 2x+1

<u>To find the value of x :</u>

m∠B + m∠C = 180

(2x+3) + (2x+1) = 180

4x + 4 = 180

4x = 180 - 4

4x = 176

x = 176/4

x = 44

<u>To find m∠C :</u>

m∠C = 2x + 1

⇒ 2(44)+1

⇒ 88+1

⇒ 89°

The measure of angle C is 89 degrees.

Solve -8x + 4 ≤ 36<br><br>A. x ≥ -4<br><br>B. x ≤ 4<br><br>C. x ≥ 4<br><br>D. x ≤ -4
nexus9112 [7]
- 8x + 4 ≤ 36
Subtract 4 from both sides.
-8x ≤ 32
Divide both sides by -8.        When dividing by a negative number change the
 x ≥  - 4                                   inequality sign.
