 Please help, Select the graph of the equation below. y=3/2x^2-6x.
valentinak56 [21]

So before we can decide which graph it is, we have to find the zeros (x-intercepts) of this graph. We can do this by setting y to 0.

Firstly, factor out 3x on the right side of the equation: 0=3x(\frac{x}{2}-2)

Next, use the zero product property to solve y = 0:

3x=0\\ x=0

\frac{x}{2}-2=0\\\\ \frac{x}{2}=2 \\ \\ x=4

So we know that the zeros of this equation are (4,0) and (0,0). Looking at the four graphs, the only graph that has a line crossing those 2 points is the first graph. Therefore, the graph of this equation is the first graph.

Justin recently drove to visit his parents who live 96 miles away. On his way there his average speed was 20 miles per hour fast
never [62]

Answer:

Justin's average speed to his parents' house: x= 40mph

Justin's average speed from his parents' house: x+20=60 mph

Step-by-step explanation:

Let the average speed be x +20  

Then average speed from his parents' x

And the distance is S=96

Then we know :

\displaystyle \frac{S}{x+20} +\frac{S}{x} =4 \\\\\\ \frac{96}{x+20} +\frac{96}{x}=4   \ |\div 4 \\\\\\ 24\bigg(\frac{1}{x+20} +\frac{1}{x} \bigg) =1 \\\\\\ 24\cdot \frac{x+x+20}{(x+20)x}  =1  \  |\cdot (x+20)x  \ \  \\\\\\48x+480=x^2+20x \\\\ x^2-28x-480=0  \\\\  \rm  D=28^2+4\cdot 480=2704 =52^2 \\\\ \boxed{x_1=\frac{28+52}{2} =40} \\\\x_2=\frac{28-52}{2} =-12 \ \  \varnothing

Justin's average speed to his parents' house:  x= 40mph

Justin's average speed from his parents' house:  x+20=60 mph
