Answer:
B
Step-by-step explanation:
First, expand the function with FOIL
(3x - 4)(-6x + 5)
(-18x² + 15x + 24x - 20)
Combine like terms
(-18x² + 39x -20)
This is a quadratic function because it has x² and linear functions just have x.
So, B is the answer because it is quadratic and it has the correct quadratic, linear, and constant terms.

Answer:
A
Step-by-step explanation:
Calculate the midpoint using the midpoint formula
[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]
with (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (5, 5)
midpoint = [ 0.5(- 1 + 5), 0.5(5 + 5) ]
= [ 0.5(4), 0.5(10) ] = (2, 5 ) → A
Answer:
40 degrees!
Step-by-step explanation:
