What is the equation of the graph below? A graph shows a parabola that opens up and crosses the x axis at negative two and negat

Anastaziya [24]

Answer:

$y=(x+3)^{2} -1$

Step-by-step explanation:

General equation of a parabola that opens up is $y=a(x-h)^{2} +k$ , a>0

So equation becomes $y=(x-h)^{2} +k$ which implies option A and option B can never be true for this parabola.

Also this parabola's vertex lies in 3rd quadrant where coordinates of both x and y will be negative.

So, the equation of parabola will be of the form $y=(x+h)^{2} - k$

Hence, option 4 that is $y=(x+3)^{2} -1$ is correct.

A van and a truck both drove from Town A to Town B. The distance

Gala2k [10]

First we need to find out the time it took for the truck to reach town B.

$Speed= \frac{Distance}{Time}$

$40= \frac{200}{T}$
$T=5hours$

Now, because the van left 1.5 hours earlier and reached the destination 2.5 hours before, it took 1 hour less the the truck to arrive.

$5hours-1hour=4hours$ which is the time it took for the van to arrive.

Now we use the speed equation again to work out speed.

$Speed= \frac{200}{4}$

$Speed=50mph$ = speed of van

Hope this helped :)

June drove 116 miles and 5.8 hours at this rate how far will she drive in 5 hours

Sonbull [250]

First we need to calculate how fast she was going in one hour:
116 / 5.8 = 20

then multiply that by 5 to get how far she will go in 5 hours

20 * 5 = 100
