Answer:
A: {(7, 12), (1, -5), (3, -10), (2, -5)}
Step-by-step explanation:
A relation should not have any repeating x values (or domains) in the group of coordinates.
B has 1 as all it's domains. B is not a function.
C lists 0 twice as it's domain. C is not a function
D lists 2 twice as it's domain. D is not a function
A is the best answer because it does not repeat any domains in the coordinates. A is a function.
Answer:
Hey there!
59 and 61 are the only prime numbers in this list.
Let me know if this helps :)
Answer:
Option A
Step-by-step explanation:
Weight of an apple = twice of the weight of a lemon
Weight of an apple = 2(weight of a lemon)
x = 2y ------(1)
x = weight of an apple
y = weight of a lemon
Number of apples in a box = 16
Weight of the apple box (A) = 16x
Number of lemons in another box = 24
Weight of the lemon box (B) = 24y
Therefore, 
[From equation (1)]
Option A will be the correct option.
Start with <span>3x+2>x+8.
Subtract x from both sides, obtaining: 2x + 2 > 8.
Subtract 2 from both sides, obtaining: 2x > 6
Divide both terms by 2: x > 3 (answer)</span>
