Answer:

(-2,8)

Step-by-step explanation:

3x+3y = 18

2x+y = 4

Multiply the second equation by -3

-3(2x+y) = -3*4

-6x-3y = -12

Add this to the first equation

3x+3y = 18

-6x-3y = -12

-------------------------

-3x = 6

Divide each side by -3

-3x/-3 = 6/-3

x = -2

Now solve for y

2x+y = 4

2(-2) +y = 4

-4+y =4

Add 4 to each side

-4+4+y = 4+4

y =8

Answer:

(-2,8)

Step-by-step explanation:

3x + 3y = 18 (1)

2x + y = 4 (2)

(1) - 3(2)

3x + 3y = 18

-(6x + 3y = 12)

-3x = 6

x = -2

Using (2)

2(-2) + y = 4

-4 + y = 4

y = 8

Answer the following 4 questions CORRECTLY I will know if this is wrong. I WILL REPORT ANY INCORRECT ANSWERS!
Shkiper50 [21]

1. A) 5 (It would be B. because it does equal 4.09 but it has to be 5 because it is the greatest integer in all of them)

2. D) 10 (Just like 1. it would be B. also BUT 10 is the greatest integer you can have out of all of them)

3. A) 6 (Just like the other 2 problems at the top^ it would be C. if not for the fact it has a higher number.)

4. A) A value we can put in place of a variable (such as x) that makes the equation true.

Since ABCD is a parallelogram, the two pairs of _________ sides (AB¯ and CD¯, as well as AD¯ and BC¯) are congruent. Then, since
Marysya12 [62]

Answer:

1. Opposite

2. angle-side-angle criterion

Step-by-step explanation:

Since ABCD is a parallelogram, the two pairs of <u>(opposite)</u> sides (AB¯ and CD¯, as well as AD¯ and BC¯) are congruent. Then, since ∠9 and ∠11 are vertical angles, it can be concluded that ∠9≅∠11. Since ABCD is a parallelogram, AB¯∥CD¯. Since ∠2 and ∠5 are alternate interior angles along these parallel lines, the Alternate Interior Angles Theorem allows that ∠2≅∠5. Since two angles of △AEB are congruent to two angles of △CED, the Third Angles Theorem supports that ∠8≅∠3. Therefore, using the <u>(angle-side-angle criterion)</u>, it can be stated that △AEB≅△CED. Then, applying the definition of congruent triangles, it can be stated that AE¯≅CE¯, which makes E the midpoint of AC¯. Use a similar argument to prove that △AED≅△CEB; then it can be concluded that E is also the midpoint of BD¯. Since the midpoint of both line segments is the same point, the segments bisect each other by definition. Match each number (1 and 2) with the word or phrase that correctly fills in the corresponding blank in the proof.

A parallelogram posses the following features:

   1. The opposite sides are parallel.

   2. The opposite sides are congruent.

   3. It has supplementary consecutive angles.

   4. The diagonals bisect each other.
