Angle 1 and angle 2 make 90 degrees and line C cuts through that so and they are equal so that makes 45 for the two of them and added together, it will equal 90.
Answer:
Step-by-step explanation:
opens down refers to the value of a being negative or positive. If it opens down, then a is negative.
shifting left or right refers to the value of h
shifting up or down refers to the value of k
For the first one: y = -a (x+8)² + k
second one: y = -a(x+h)² + 7
Step-by-step explanation:
F ( x ) = x² + 2x - 24
{ factorising by middle term splitting method }
[ 24 = 2 × 2 × 2 × 3 ]
F ( x ) = x² + 6x - 4x - 24
F ( x ) = x ( x + 6 ) -4 ( x + 6 )
F ( x ) = ( x + 6 ) ( x - 4 )
