Answer:

a= 3

b=-4

c=-8

Step-by-step explanation:

3x²=4x+8

since the 4X is positive it will cross the equal sign and become negative and the same goes for 8,and this will leave nothing on the right of the equal sign therefore it will become 0

3x²-4x- 8= 0

the above equation is now in the form required

ax²+bx+c=0

so substitute the values according and u will see that a= 3

b=-4 and c=-8

hope this helps

a parabola contains the points (0,0),(-1,-2) and (1,6). what is the equation of the parabola in standard form?
tensa zangetsu [6.8K]

Let the equation be:

y = ax^2 + bx + c.

Then, substitue the three points into the equation.

First point: 0 = a0^2 + b0 + c.

So  c = 0.

Second point: -2 = a(-1)^2 + b(-1) + c.

So  a - b + c = -2.

Third point: 6 = a*1^2 + b*1 + c.

So  a + b + c = 6.

We know that c=0 already, so we substitute c=0 into the last two equations and we would get:

a - b = -2

a + b = 6

We add the two equations and we get:

2a = 4

a = 2

Then, we substitute a=2 into a-b=-2 and we get:

-b = -4

b = 4

Now we know a = 2, b = 4, and c = 0

Then, the equation of the parabola would be:

2x^2 + 4x

There are 5040 ways for a group of 7 people to be seated. How many ways could a group of 8 seated explain how you figured it out
Dovator [93]

The number of ways is 40320

<h3>How many ways could a group of 8 seated?</h3>

The group of people is given as:

Group = 8

The number of ways this group can be seated is calculated as:

Ways = Group !

So, we have

Ways = 8!

Expand

Ways = 8 * 7 * 6 * 5 * 4 * 3 *2 *1

Evaluate

Ways = 40320

Hence, the number of ways is 40320
