Complementary angles have a sum of 90 degree, right angle
It would be C. Since it’s the only 2 angles that form a right angle
Answer:
h=2
a=4
k= -21
Step-by-step explanation:
your h and k are vertex . h= x coordinate of vertex and k= y
so formula for vertex coordinates is x= -b/2a and y= (4ac-b²)/4a
your a b c are 4 -16 and -5 respectively according to the main equation
your a is concavity which is the same number as the 'a' of the equation
Answer:
c
Step-by-step explanation:
Isolate x; you must get all the constants on one side of the equation and the variables on the other side. Use subtraction/addition to do this. Reply to me once you've done that if you still need help.
