The missing justification in the proof is
<span>B) Substitution property of equality
The expression for sin</span>² x and cos² x is substituted to the other side of the equation. Since sin x = a/c, then sin² x = a²/c². Similarly, since cos x = b/c, then cos² x = b²/c². Adding to two results to the third statement.
The answer is 63, 42*.5= 21 42+21=63
Correct!
The slope is (14-6)/(9-5) = 8/4 = 2;
<span>the slope-intercept form of the function that contains the points (5, 6) and (9, 14) is y - 6 = 2( x - 5 );
Then, y - 6 =2x - 10;
y = 2x - 4 ;</span>
Since each basket in basketball is 2 points, then 2 * 5 = 10. If Cathy makes 6 more points from free throws, which are each one point, then you would have to do 10 + 6, which equals 16. So in total, Cathy scored a total of 16 points.
