Answer:

substitution

Step-by-step explanation:

We assume the two equations are ...

  • x = 2y+4
  • 2x -3y = 11

You are given an expression for x. Using that in the second equation will result in an immediate solution for y.

... 2(2y+4) -3y = 11 . . . . . substituting 2y+4 for x

.. y +8 = 11

... y = 3

... x = 2·3 +4 = 10

The solution is (x, y) = (10, 3)

Help me find the X please !! Thank youu
Elenna [48]
We can use the vertical angle theorem which states that any two opposite angles are congruent. So, you can just set the two measures equal to each other and solve for x:
7x-99=2x+1
5x-99=1
5x=100
x =  \frac{100}{5} = 20

So, your answer is 20°.

Figure ABCD is a parallelogram. If point C lies on the line y= -1, what is the x-value or point C?
MrRa [10]

Answer:

The correct answer is option D.  4

Step-by-step explanation:

Points to remember

Opposite sides of the parallelogram are equal.

From the figure we can see that,AB and CD are opposite sides.

Therefore AB = CD

<u>To find the length of AB</u>

From the figure we get, AB = 4 units

Therefore CD = 4 units

<u>To find the x coordinate of point C</u>

y coordinate is -1

x coordinate is 4 units from point D

x coordinate of D is 0, therefore x coordinate of C = 0 + 4 = 4

The correct answer is option D. 4
