A tennis ball bounces based on this equation y = x2 - x+2. A dog jumps based on this equation y=2x.
valentina_108 [34]

Answer: when the equations are equal, that is when  x = 1 or x = 2

Step-by-step explanation:

The dog will receive the ball , when both equations intercept , that is , when both equations are equal. This implies :

x^{2} - x + 2 = 2x

x^{2} - x - 2x + 2 = 0

x(x-1) - 2 (x - 1 ) = 0

(x - 1 ) ( x - 2 ) =0

Therefore , x = 1 or x = 2

There's so many numbers in this one shape I'm confused ._.
Svetlanka [38]
The answer should be 12 units^2

starting from the left side of the shape you multiply base 2 by height 2 which gets 4 then divide by 2 since it is a triangle. next multiply 2x2 for the square in the middle which gets you 4. lastly multiply 6x2 for the triangle on the right which gets you 12 however bc it is a triangle you must divide by 2 and get 6. then add them all together and you get 12.
