The points P(2,3) , Q(-1,1) and R(5,-1) are the vertices of a triangle PQR.Find the equation of the altitude of the triangle PQR
vfiekz [6]

Answer:

y = \frac{3}{4} x+ \frac{7}{4}

Step-by-step explanation:

The slope of straight line PR where P(2,3) and R(5,-1) are two vertices of triangle PQR will be = \frac{3-(-1)}{2-5} =-\frac{4}{3}

Therefore, the slope of the altitude passing through Q(-1,1) will be \frac{3}{4} {Since, the product of slopes of two perpendicular straight line is -1}

So, equation of the altitude is y=\frac{3}{4} x + c where c is a constant.

Now, putting x = -1 and y = 1 in the above equation we get  

1 = -\frac{3}{4} + c

⇒ c=\frac{7}{4}

Therefore, the equation of the altitude is y = \frac{3}{4} x+ \frac{7}{4} (Answer)

Find AC for the quadrilateral
Airida [17]

The quadrilateral ABCD is an isosceles trapezoid, and the length of AC for the quadrilateral is 19 feet

<h3>How to determine the length of AC?</h3>

The quadrilateral ABCD is an isosceles trapezoid

This means that:

  • Opposite sides are equal
  • The diagonals are also equal

From the above highlights, we have:

AC = 7ft + 12ft

Evaluate the sum

AC = 19 ft

Hence, the length of AC for the quadrilateral is 19 feet

Bag of sweets £1.50 per bag, buy 3 get 1 free how many sweets can you buy for £9
IgorLugansk [536]

Answer: 8

if you're talking about how many bags of sweets you can BUY, as in without counting the ones you got for free, it's 6. if you're talking how much you GOT, it's 8.

Step-by-step explanation:  you can multiply 1.5 times an unknown number to get nine. the unknown number would be the number of bag of sweets you get without the "buy 3 get 1 free" thing. You can reverse the equation to get 9 divided by 1.5 equals 6.

you can then divide 6 by three, which is 2- meaning you got two free bags of sweets. 6 plus 2 is 8.
