Here , the ratio <em><u>UV:</u></em><em><u>VW</u></em> and <em><u>UT:TS</u></em> will be in proportion , so ;
Putting the given values ;
The decimal equivalent is 0.25.
Add the two angles and set them equal to 180, them solve for x
-7(k+9)=9(k-5)-14k
-7k-63=(9k-45)-14k
-7k-63=-5k-45
-7k=-5k+18
-2k=18
k=-9
The correct answer is C) F(x)= x^2+4
one way to tell this is correct is the y-intercept is at positive 4
