Here's how to find the value of x:
<span>9 - 0.75 ( x + 8 ) - 5 = -6.5      find the difference of 9 - 0.75
</span><span>8.25 ( x + 8 ) - 5 = -6.5           add 5 to both sides
</span>
8.25 ( x + 8 ) = -1.5                distribute 8.25 to x and 8
8.25x + 66 = -1.5                    subtract 66 from both sides
8.25x = -67.5                          divide both sides by 8.25
x = 18.18181818......            the value of x is 18 2/11
hope this helps

Answer:
 (0, -9).
Step-by-step explanation:
The general form of the equation of a circle is:
(x - a)^2 + (y - b)^2 = r^2
where the center = (a, b).
x2 + (y + 9)2 = 25
Comparing this to the general form we see that the center = (0, -9).
 
        
             
        
        
        
The incenter of a triangle is where the angle bisectors of the triangle meet. That means angle A is 64, angle B is 74, and using the triangle angle sum, angle C is 42 degrees. Divide that in half to get the measure of DCA, 21 degrees.
