Answer:

The value of x is 4 and y is (-9)

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • x + 2y = -14
  • x – y = 13
<h3><u>To </u><u>Find</u>;</h3>
  • Value of x
  • Value of y
  • By Elimination Method

Now, Name the equation

x + 2y = -14 ...(1)

x – y = 13 ...(2)

Now,

x + 2y = -14

x – y = 13

<u>– + –</u>

3y = -27

y = -9

Now, put the value of y in equation 2

x – y = 13

x – (-9) = 13

x + 9 = 13

x = 4

Thus, The value of x is 4 and y is (-9)

<h3><u>For </u><u>Verification</u>;</h3>

x + 2y = -14

4 + 2(-9) = -14

4 – 18 = -14

-14 = -14

x – y = 13

4 – (-9) = 13

4 + 9 = 13

13 = 13

Hence, L.H.S = R.H.S

Answer:

y=-25, x=-12

Step-by-step explanation:

1 subtract both equations from each other vertically.

x-x=0,

2y-y=1y

-14-13=-25

1y=-25

y=-25

2. Find x using y

x--25=13

x+25=13

x=-12

What if it is that cool pirate money that is shaped weird? I hear it is 11/12 foot long and ¾ wide. What is the square foot of t
cestrela7 [59]

If you are asking how to find the square feet of the "weirdly shaped pirate money" you'd need to multiply the length and width. So:

11/12 * 3/4 = 33/48

So the answer is 33/48 square feet

If you are not asking for this answer word your question better please.

5 × 5 = 25

144 + 25 = 169

√169 = 13

13 × 13 = 169 therefore the length of the missing side is 13 hope that helps!

The correct answer is a right?
svetoff [14.1K]

We can see that a and b are parallel, and c and e are parallel, so the correct option is E.

<h3>Which line must be parallel?</h3>

On the diagram, we can see that the angles in the third quadrant of the intersections between a and c, and the intersections between b and c,  are the same angle.

Then, lines a and b must be parallel.

For the intersections with line d, we can see that this time the angle is on the fourth quadrant, so c and d are not parallel.

Finally, for line e, we can see that the known angle is on the first quadrant.

Notice that the angle on the first quadrant will be equal to the angle on the third quadrant.

So for the intersections of a and e, and b and e, on the third quadrant we have the known angle (the same one as in the intersections of a and c, and a and b).

Then c and e are parallel.

Then A and C are true.

Thus, the correct option is E.
