Answer:
b =15
Step-by-step explanation:
We can use Pythagoras theorem to find b:
64 + 
= 289
64 + 225 = 289
64 + 
= 289
b = 15
hope this helps :) and sorry if not right
27 divided by 40 is equal to 0.675.
G^2+2=0,
g^2=-2
g= sqrt-2, not possible.
3g+1=0
3g=-1
g=-1/3
9 cannot be equal to zero for the last one.
Which of the sets of ordered pairs represents a function? (4 points) A = {(−4, 5), (1, −1), (2, −2), (2, 3)} B = {(2, 2), (3, −2

A function will not have any repeating x values....it can have repeating y values, just not the x ones
(-4,5),(-1,1),(2,-2),(2,3)
this is not a function because it has 2 sets of points that has x as 2...so it has repeating x values
(2,2),(3,-2),(9,3),(9,-3)
this is not a function because it has 2 sets of points that has an x value of 9...so it also has repeating x values
so both of these are not functions.....neither of them
