Answer:
-4(3n + 5).
Step-by-step explanation:
The common factor is - 4 so you take this out to give:
-4(3n + 5).
Answer:
0.4x
Step-by-step explanation:
M = (x₁ + x₂)/2 , (y₁ + y₂)/2
(-1, 2) = 
At this point, it is easier to separate the x's and y's into two different equations:
x's: -1 = 
-2 = 3 + x
-5 = x
y's: 2 = 
4 = 4 + x
0 = x
Answer: (-5, 0)
For this problem all you have to do is plug in the value that they is in parenthesis for x. If it says g (x) = x and then it asks g(5) = ?, it is saying what happens if i put 5 in for every x. in this case it would be g (5) = 5. I just replaced x with 5.
So g (-2) we sub -2 for x
g (-2) = -2 (-2)^2 + 3 (-2) - 5
= -2 (4) - 6 - 5
= -19
g (0) = -2 (0) + 3 (0) - 5
= 0 + 0 - t
= -5
g (3) = -2 (3)^2 + 3 (3) - 5
= -18 + 9 - 5
= -14
