You only did the last one wrong, (3/4) times 2 is 3/2. 3/2 - 1/2 is 2/2 or 1.
So it'd be (2,1)
The idea is to group up the terms into two groups, factor each group and then factor out the overall GCF
2x - 18 + xy - 9y
(2x - 18) + (xy - 9y)
2(x - 9) + (xy - 9y)
2(x - 9) + y(x - 9)
(2 + y)(x - 9)
(x - 9)(2 + y)
Answer: Choice B
Answer:
C. ASA
Step-by-step explanation:
The details of the given parameters are;
Angle ∠B of ΔABC is congruent to angle ∠E of triangle ΔDEF,
Angle ∠C of ΔABC is congruent to angle ∠F of triangle ΔDEF
Side 
of ΔABC is congruent to side 
of triangle ΔDEF
Two angles (∠B and ∠C) and the included side (side ) of ΔABC are congruent to the corresponding two angles and included side (∠D, ∠E and side ) of ΔDEF, therefore, the two triangles are congruent by the Angle-Side-Angle, ASA, rule of congruency
They are functions because they have the variables
