PLZ HELP 100 PTS!!!!!!!!!!!!!!!!!
erma4kov [3.2K]

Answer:

x = 12

Step-by-step explanation:

The mistake made here is in making 130 = 9x + 7. They are not the same.

The central angle = 130 degrees.

Any angle sharing the endpoints of the central angle and having it's vertex on the same side of the central angle is 1/2 the central angle.

1/2 the central angle = 130 /2 = 65

Cyclic quadrilaterals (those with all 4 points touching a circle's circumference) have opposite angles  supplementary.

65 + 9x + 7 = 180           Combine like terms on the left

72 + 9x = 180                 Subtract 72 from both sides

72 - 72 + 9x = 180-72     Combine

9x = 108                          Divide by 9

9x/9 = 108/9                  

x = 12

18) Value of b is : b\geq  8

Option A is correct.

19) Option C is correct.

Step-by-step explanation:

18) We need to find the value of b.

The given equation is:

12b-46\geq 50

Solving to find the value of b:

12b-46\geq 50\\12b\geq 50+46\\12b\geq 96\\b\geq \frac{96}{12}\\b\geq  8

So value of b is : b\geq  8

Option A is correct.

19) We need to find the correct graph of the equation:

4y-2

Solving:

4y-2

The values of y will be less than three. As y < 3 so, the circle on y is not filled.

So. Option C is correct.
