Step-by-step explanation:
It is required to find the expressions that are equivalent to 4-x. We can also write it as :
Option (b) : (4-x) = 4+(-x)
Option (c) : (4-x) = -x+4
Hence, the correct options are (B) and (C).
Answer:
12 toys
Explanation:
Rita put away 12 toys because she put away all of the toy dogs (6) and all of the toy cats (6). 6 + 6 = 12. So, she put away a total of 12 toys.
Answer: 3(x^2 + 4)/(x - 5)(x + 4)
Step-by-step explanation:
To simplify, begin with 3x^2 + 12 by dividing by 3 first: 3(x^2 + 4)
x^2 - x - 20 can be simplified into (x - 5) (x + 4). To find these terms, you have to figure out what two numbers multiply together to equal -20 but also add to -1.
Answer:
I think you are correct
Step-by-step explanation:
Answer:
Step-by-step explanation:
If you treat 90° as 1 unit on the graph, then
P(1,0) corresponds to (0,0) and (360,0) on the sin graph (say (0,0) though)
P(0,1) corresponds to (90,1) on the sin graph
P(-1,0) corresponds to (180,0) on the sin graph
P(0,-1) corresponds to (270,-1) on the sin graph
