Answer:
The correct option is 4. Neither A nor B represents a function.
Step-by-step explanation:
The given sets of ordered pairs are


A set of ordered pairs represents a function if there exist unique outputs for all inputs. It means for each values of x there exist, a unique value of y.
In set A the value of y-coordinates are -5 and 7 at
.
At x=8, there exist more than one value of y, so the set A is not a function.
In set B the value of y-coordinates are -4 and -2 at
.
At x=7, there exist more than one value of y, so the set B is not a function.
Therefore neither A nor B represents a function and option 4 is correct.
7+ (-5) = 2.
Therefor, 4^2 would be the right answer.
Answer:
A. 8
Step-by-step explanation:
sqrt{64} is 8 (8*8)
Answer: x * y = 1
Explanation: The only thing that changes between the examples are the first two numbers; the final answer is always 1. This would mean that the first number (x) multiplied by your second number (y) will always answer or equal 1.
Answer:
Las opciones no se pueden ver, así que responderé de una forma general.
Primero rompamos la frase en partes más cortas
"cuatro veces un número..."
Esto se escribe como 4*N, donde N es el número.
"... la suma de dos
números"
Esto se escribe como K + M
donde K y M son dos números, entonces K + M es la suma de dos números.
Entonces:
"cuatro veces un número dividido por la suma de dos
números"
Se escribirá como:
(4*N)/(K + M )
