Answer:
A)
3a2 – 2b2 – 2c2 – ab + 5ac + 5bc
Answer:
slope = 5
Step-by-step explanation:
Parallel lines have the same slope
Equation: y = mx + b
So, slope m = 5
Answer:
(-5,7) (5,-7)
Step-by-step explanation:
When you are told to lable, show or name the points that lie on a horizontal line, it basically means that; when a line is drawn, it passes through the selected points without changing the direction when joined together (horizontally).
From the above problem, (-5,7) and (5,-7) lie in the same horizontal line.
For (7,-5) and (-7,5) lie in the same vertical line.
Thereforeour, the answer is (-5,7) (5,-7).
We first need to pick the correct piece to use. In this case, we will use f(x) = -x-5 because -5<=-4.
Then, we use direct substitution:
f(-4) = -(-4) - 5
f(-4) = -1
