Answer:

  1

Step-by-step explanation:

The ratio of the x coefficient to the y-coefficient is different in each equation, so the equations are for lines of different slope, so there is one solution.

__

The solution can be found by subtracting the second equation from the first:

  (x +4y) -(x +2y) = (8) -(4)

  2y = 4

  y = 2

  x + 2(2) = 4 . . . . substitute into the second equation

  x = 0 . . . . . . . . . subtract 4

The one solution is (x, y) = (0, 2).

Given: <br> PQ<br> ⊥<br> QR<br> , PR=20,<br> SR=11, QS=5<br> Find: The value of PS.
dlinn [17]

Answer:

The value of the side PS is 26 approx.

Step-by-step explanation:

In this question we have two right triangles. Triangle PQR and Triangle PQS.

Where S is some point on the line segment QR.

Given:

PR = 20

SR = 11

QS = 5

We know that QR = QS + SR

QR = 11 + 5

QR = 16

Now triangle PQR has one unknown side PQ which in its base.

Finding PQ:

Using Pythagoras theorem for the right angled triangle PQR.

PR² = PQ² + QR²

PQ = √(PR² - QR²)

PQ = √(20²+16²)

PQ = √656

PQ = 4√41

Now for right angled triangle PQS, PS is unknown which is actually the hypotenuse of the right angled triangle.

Finding PS:

Using Pythagoras theorem, we have:

PS² = PQ² + QS²

PS² = 656 + 25

PS² = 681

PS = 26.09

PS = 26
