miskamm [114]

Answer:

y= 1x - 1

Step-by-step explanation:

Slope-intercept form: y=mx + b

(-4,-5) (5,4)

m= (y2 - y1)/(x2 - x1) = (4+5)/(5+4)=1

4=1(5)+b

4=5 + b    4-5=b    b= -1

5. A pole has to be erected at a point on the boundary of a circular park of diameter 13 metres in
lesya [120]

Answer:

Thus, it is possible to erect a pole at a point p on the boundary of the park at distances 5m and 12m respectively from gates B and A.

Step-by-step explanation:

Let P be the required location of pole .

A and B are the two gates.

Let the distance of pole at p from gate be 'x' meters

i.e. PB = x m

•°• AP = (x + 7)m and AB = 13 m

•°• AP² + BP² = AB² => (x +7)² + x =13²

Rejecting x =-12, we get x = 5

•°• PB = 5m

and

AP = 12m

Answer:

Step-by-step explanation:

  • Orchestra Seats: Balcony seats + 7
  • Orchestra Seats: 600
  • Balcony Seats: 120
  • Total Amount of Sales: 13,560

A.) 600 x 20 = 12,000

    120 x 27 = 3,240

     12,000 + 3,240 = 15,240

B.) 600 x 13 = 7,800

     120 x 20 = 2,400

     7,800 + 2,400 = 10,200

C.) 600 x 18 = 10,800

    120 x 25 = 3,000

    10,800 + 3,000 = 13,800

D.) 600 x 11 = 6,600

     120 x 18 = 2,160

     6,600 + 2,160 = 8,760
