Answer:
C. {(–1, 3), (0, 4), (1, 14), (5, 6), (7, 2)}
Step-by-step explanation:
I just did the quiz. Basically all you do is switch the x and y values for each coordinate pair in order to see if it would pass the line test. If it has double X values, it is not a function with an inverse function.
Let x be the smaller number.
So the bigger number is x+19 (Their difference is 19)
Their sum: 53
Answer:
Step-by-step explanation:
using pythagoras theorem
a^2 + b^2 = c^2
B^2 + 8^2 = 15^2
B^2 + 64 + 225
B^2 = 225 - 64
B^2 = 161
B =
OR 12.7
