<span>4x + 2y = 4
6x - 8 = -2y

Both equations are divisible by 2, so divide both sides of both equations by 2.

</span><span>2x + y = 2
3x - 4 = -y

Since the second equation has -y on one side, we can multiply both sides by -1 to solve for y.

y = -3x + 4

Now we substitute y of the first equation with -3x + 4.
This is the substitution method.

2x + y = 2

2x - 3x + 4 = 2

-x + 4 = 2

-x = -2

x = 2

Now we substitute 2 for x in the first original equation and solve for y.

4x + 2y = 4

4(2) + 2y = 4

8 + 2y = 4

2y = -4

y = -2

The solution is x = 2 and y = -2

What is 0.0162 as a fraction
CaHeK987 [17]
You have to ask yourself how would you read that decimal?  It is 162 ten-thousandths because the last digit, which is 2 is in the ten-thousandths place. So the fraction would be 162/10000

Which assumption(s) must be used to prove that vertical angles are congruent?
ivanzaharov [21]

Answer:

The assumption to prove that vertical angles are congruent is "Vertical angles are always congruent".

Step-by-step explanation:

Vertical angles are a pair of angles (not adjacent) opposite each other by a vertex when two lines intersect.

When two lines intercept at a point, 4 angles are formed. Those that are opposite to each other and are not adjacent are vertical angles, these are always congruent.

In this case, we can affirm that if two angles are opposed by the vertex, they are equal.

Have a nice day!
