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

MArishka [77]
<span>From my research, the question had the following choices:

the number of songs played on each channel     
the weather conditions of the city
the number of music lovers in the city
the duration of each concert

Among the choices, the correct answer is "the number of music lovers in the city". The more concerts there are in a city corresponds to the number of music lovers. Radio channels usually play music, so having a lot radio channels in a city must mean that there is a large audience.</span>

7 - 3x = 3 ( 3- x ) - 2<br><br> Please help &amp; show how you got to the answer
Leokris [45]
Step 1: Simplify both sides of the equation.
7−3x=3(3−x)−2
7+−3x=(3)(3)+(3)(−x)+−2(Distribute)
7+−3x=9+−3x+−2
−3x+7=(−3x)+(9+−2)(Combine Like Terms)
−3x+7=−3x+7
−3x+7=−3x+7
Step 2: Add 3x to both sides.
−3x+7+3x=−3x+7+3x
7=7
Step 3: Subtract 7 from both sides.
7−7=7−7
0=0
So all real numbers
