let x = {p ∈ z | p = 5a + 2 for some integer a}, y = {m ∈ z | m = 4b + 3 for some integer
b}, and z = {n ∈ z | n = 4c − 1 for some integer c}.
is x ⊆ y ? (2pts)
justify your answers carefully. (in other words, provide a proof if the statement is true or a disproof if the statement is false.) (8 pts)

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

1. perpendicular

2. parallel

3. perpendicular

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
