Factorise: 4ay-2y can’t seem to do this

Mathematics
1 answer:
qaws [65]4 years ago

In order to factor, we must pull out factors common to each term. In this case, each term has factors of 2 and y:

4ay = 2 * 2 * a * y
2y   = 2 * y

So, we'll pull out the 2y:

2y(2a-1)

To check, distribute the 2y back through the terms in parentheses to ensure you end up with the original expression 4ay - 2y.

<h3>Answer: Choice C</h3>

Converse of the corresponding angles postulate

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

Explanation:

The corresponding angles postulate says that if we have two parallel lines, then the corresponding angles are congruent.

The converse of this is where we go in reverse: if we know the corresponding angles are congruent, then the lines are parallel.

Corresponding angles are ones where they are on the same side of the transversal line, and also on the same side of each adjacent parallel line. In this case, the angles 52 are to the right of the tranversal, and each are above their neighboring parallel line. We could say the two corresponding angles are both in the upper right hand corner (think of the two lines crossing to form 4 corners or regions)

Determine the solution to the given system of equations. -2 equals negative y minus x. Y equals negative 1 minus x
elena-s [515]

Answer:

The system of equations has no solutions

Step-by-step explanation:

Here, we want to solve the system of equations simultaneously;

-2 = -y - x

y = -1 - x

Substitute the second into the first

-2 = -(-1-x) - x

-2 = 1 + x - x

We can see that the system has no solutions
