Answer:

(8, -4)

Step-by-step explanation:

When you cancel the terms out by subtracting the second equation by the first, you get 4y = -16, which means y = -4. Then you can plug it back in to any eauation. For example, we can do the second one, 4x + 6(-4) = 8. This sumplifies to 4x + -24 = 8. Add 24 to both sides which gets us 4x = 32, and then you get x which is 8. The ordered pair is (8, -4). Hope this helps! (this is my first answer)

Whoever answers correctly will recive a brainleist and 10 pts please asap ! :)
Gnesinka [82]

Answer:

y = -1/2x - 2

Step-by-step explanation:

The line is negative, so the slope has to be negative. (-1/2)

You would use the equation to find the first point to plot. -1/2 times 0 is 0. 0-2 equals -2. This means that the first point would be (0,-2). This proves that the correct equation is <u><em>y = -1/2x - 2</em></u>.

  • The angles are supplementary angles
  • The measure of angle m<1 and m<2 are 72 and 108 degrees respectively

Find the diagram attached. From the figure, the sum of the angles m<1 and m<2 are supplementary

Given the following angles

m<1 = 2x + 6

m<2 = 3x + 9

Since both angles are supplementary, hence;

2x + 6 + 3x + 9 = 180

5x + 15 = 180

5x = 180 - 15

5x = 165

x = 165/5

x = 33

Get the measure of m<1;

m<1 = 2x + 6

m<1 = 2(33) + 6

m<1 = 66 + 6

m<1 = 72degrees

Get the measure of m<2:

m<2 = 180 - m<1

m<2 = 180 - 72

m<2 = 108degrees

Hence the measure of angle m<1 and m<2 are 72 and 108 degrees respectively
