Answer:

B. 16

Step-by-step explanation:

Since AB and AD are tangent to circle C, they equal each other.

2x + 7 = 3x - 9 Make them equal each other

2x + 7 = 3x - 9 Subtract 2x from both sides

7 = x - 9 Add 9 to both sides

16 = x

Graph the equation <br><br>2x + 3y = 9

jeka57 [31]

$2x + 3y = 9\\3y = -2x + 9\\y = -\frac{2}{3}x + 3$

Look at the graph picture I attached

$y = mx + c$

c is the intercept, which is why the graph crosses the y-axis at +3

to find where it crosses the x-axis, we make y = 0

$y = 0\\\to -\frac{2}{3}x + 3 = 0\\-\frac{2}{3} = -3\\\frac{2}{3}x = 3\\2x = 9\\x = \frac{9}{2}\ \ (=4.5)$
