We have (1,4) + (-1,-4) = (0,0), because 1 + (-1) = 1 - 1 = 0 and 4 + (-4) = 4 - 4 = 0.
Answer:
-6c + 7
Step-by-step explanation:
To simplify this expression, you must add like terms. Because 3c and -9c both have the same variable (c), they are like terms.
3c + (-9c) = -6c
The 7 stays the same, so the simplified expression is -6c + 7.
Hope this helped :)

Answer:
B) 5 x 4 x 3 x 2 x 1
Step-by-step explanation:
When you see a ! directly next to a number (such as 5!), it means that you are multiplying starting from that number, and stepping down each time:
5! = 5 * 4 * 3 * 2 * 1
For example, take factoral 10: 10!
10! = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 3,628,800
In this case, you are multiplying 5!.
5! = 5 * 4 * 3 * 2 * 1 = (20) * (6) * 1 = 120
5! = 120
Answer:
x=16; y=24
Step-by-step explanation:
for (x,23), 23=0.5x+15
x=16
for (18xy), y=0.5*18+15=24
