Is there’s more to this question?
X: # of pairs of socks; y: # of blouses
Then $2.99x+$12.99y=$43.92.
Answer:
The answer is D) (-1, -1)
Step-by-step explanation:
In order to find which answer is a solution, you have to put the ordered pair in for their given variables. If it produces a true statement, then it is a solution. In this case, D is the only one that produces a true statement.
2x + y > -4
2(-1) + (-1) > -4
-2 - 1 > -4
-3 > -4 (TRUE)
Use pythagorean theorem
c2 = a2+b2
c2 = 16^2 + 12^2
c2 = 256 + 144
c2 = 400
c = 20
