Determime whether each of the following is a prime or composite number

1 answer:

5 0

Hi! Since prime numbers only have 1 and themselves as factors, 101 would be prime. 123 has factors of 1,3,41,123, so it would classify as a composite number. I hope this helps!:)

Answer:

$y = \frac{7}{4} x - 3 \\ y = x \\ y = \frac{7}{4} y - 3 \\ y - \frac{7}{4} y = - 3 \\ - \frac{3}{4} y = - 3 \\ 3y = 12 \\ y = \frac{12}{3} \\ y = 4 = x$
