Which set of ordered pairs represents a function? {(2, –2), (1, 5), (–2, 2), (1, –3), (8, –1)} {(3, –1), (7, 1), (–6, –1), (9, 1

A function can't have x repeating any of the same number twice for example the first one (2, -2), (1, 5), (-2, 2), (1,-3), (8,-1) you have two 1's (1,5) and (1,-3) the x is the first number. Now a function can have the same y value. So your answer is (3, -1), (7,1), (-6,-1), (9,1), and (2,-1) you have to have all different x values in order for it to be a function. Hope that helps.
Answer:
a= (y-4x-6)/X
Step-by-step explanation:
Make ax the subject of the formulae
-ax=4x+6-y
Multiply both sides by minus (-)
ax= y-4x-6
Divide both sides by x
a= (y-4x-6)/x
Answer:
This equation has one solution so given statement is true.
Step-by-step explanation:
7a +4 – 2a = 7a + (-20)+4
5a + 4 = 7a - 16
5a - 7a = -16 - 4
- 2a = - 20
a = 10
This equation has one solution so given statement is true.
