Answer:

(-2 , -3) and (0.6 , 4.8)

Step-by-step explanation:

y=3x +3

(x - 2)² + y² = 25

(x - 2)² + (3x +3)² = 25

x²-4x+4+9x²+18x+9-25=0

10x²+14x-12=0

5x²+7x-6=0

(x+2)(5x-3)=0

x = -2 or x = 3/5 (-0.6)

y = -3 or y = 4 4/5 (4.8)

anygoal [31]

Alright, lets get started.

Mr. Hinckley owns 83 acres of total land.

He divides the land into eight equal sections to sell to eight buyers.

It means, we could find the land each buyer receives by dividing total land by 8.

So, each buyer receives land = $\frac{83}{8}$

So, each buyer receives land = 10.375 acres

So, the answer is 10.375 acres lands received by each buyer. : Answer

CINEMA A sells each movie pass for $5.50, and CINEMA B sells each movie pass for $5.60.

To find the cost of each pass in Cinema A, all you would have to do it divide 66 by 12, where you would get 5.5, which in other words would be $5.50. And to find the cost of each pass in Cinema B, you wound divide 28 by 5,and you would get 5.6, which is in other words, $5.60.
