Answer:
(c, b)
Step-by-step explanation:
Add the coordinates together and divide by 2
x coordinates: 2c + 0 = 2c, divided by 2 = c
y coordinates: 0 + 2b = 2b, divided by 2 = b
Answer:
Step-by-step explanation:
The range would only include positive integers.
Answer:
I think it is (x^2+9) x (x-1) x (x+1)
Step-by-step explanation:
(not sure if right but had a go)
3^(4x) = 3^(5 - x)
4x = 5 - x
4x + x = 5
5x = 5
x = 5/5 = 1
x = 1

Negative multiply negative = Positive
Negative multiply positive = negative

Thus the answer is -4a + 16b - 12c - 12d.
