The graph of the line segment PQ is attached. To find the length, we have to use distance formula which is

d = \sqrt{ (x_{2} -x_{1} )^2 + (y_{2} - y_{1} )^2  }

PQ = \sqrt{ (2-(-2))^2 + (4- (-1))^2 } = \sqrt{ (2+2)^2 + (4+1)^2 }

PQ = \sqrt{16+25} = \sqrt{41}

To find the midpoint,we have to use the formula

( \frac{x_{1}+ x_{2} }{2} ,\frac{y_{1}+ y_{2} }{2} ) = (\frac{-2+2}{2} , \frac{-1+4}{2} )

= ( \frac{0}{2} , \frac{3}{2} ) = (0 , \frac{3}{2} )

Points scored in a basketball game vary directly with shots taken. If a player scores 50 points and takes 40
KATRIN_1 [288]

Answer:

She would have scored 75 points.

Step-by-step explanation:

Points scored in a basketball game vary directly with shots taken.

This means that this question can be solved by proportions, using a rule of three.

How many would she have scored if she takes 60 shots?

Using a rule of three:

50 points - 40 shots

x points - 60 shots

Applying cross multiplication:

40x = 50*60

Dividing both sides by 40

x = 50*1.5 = 75

She would have scored 75 points.

15x = 3x + 120 (subtract both sides by 3x)
12x = 120 (divide both sides by 12)
