How do I turn 5 — 3(х+1) — 2y — 3х + 2 into an y=mx+b form

7nadin3 [17]

Answer:

y = -3x + 2

Step-by-step explanation:

Ok so I assumed that you are setting this equal to 0 or there would be an equal sign in the equation. So basically you just want to gather like terms on each side so the y's on the left and the x's on the right. You then want to solve using algebra and you have your answer! I will add a picture to show my steps.

If the set U = {all positive integers} and set A = {x|x ∈ U and x is an odd positive integer}, which describes the complement of

dlinn [17]

Answer: Choice D) set of even integers

=======================================================

Explanation:

U = universal set = {all positive integers} = {1, 2, 3, 4, 5, ...}

A = {stuff in set U that is odd} = {1, 3, 5, 7, 9, ...}

$A^c$ = {stuff in set U but NOT from set A} = {2, 4, 6, 8, ...}

$A^c$ = {set of even numbers from set U}

In set theory, the complement is simply the complete opposite. If the number 7 is found in set A for instance, then 7 is not going to live in the complement $A^c$

The opposite of the odd numbers is the set of even numbers.

Therefore, we go for choice D as our final answer.

Side note: if we union set A with its complement $A^c$ then we get the universal set as a result. $A \cup A^c = \text{universal set} = \text{set of all positive integers}$
