Damm [24]3 years ago
4 0

Answer:

x= 4, 2.5(or 5/2)

Step-by-step explanation:

2x²-3x-15=5

           -5   -5

2x²-3x-20=0

plug into quadratic equation

(3+13)/4           (3-13)/4

16/4=4             10/4=2.5

At which values of x does the function F(X) have a vertical asymptote? F(X) =3/x(x-5)(x+1)
damaskus [11]

Answer:

There are vertical asymptotes at x:  {-1, 0, 5}

Step-by-step explanation:

It's easier (at least for some) if you write this function as

                  3

F(X) = ------------------

            x(x-5)(x+1)

Can you now see that if x = 0, this function is undefined?  Same for x = 5 and x = -1?  There are vertical asymptotes at x:  {-1, 0, 5}

Adam went on a 54 \text { km}54 km54, start text, space, k, m, end text hike. He divided the distance traveled evenly over 666 d
astra-53 [7]

Answer:

9000 metres

Step-by-step explanation:

He went on a 54 km hike. First, we have to find this distance in metres.

1 km = 1000 m

54 km = 54 * 1000 = 54000 m

He divided the distance evenly over 6 days.

To find how many metres he walked each day, we divide the total distance he hiked by the number of days spent. That is:

54000 / 6 = 9000 metres

He walked 9000 metres each day.

Set each equations equal to each other

{x}^{2}  + 4 = 4x

{x}^{2}  - 4x + 4

Find the discrimant.

{ - 4 {}^{2} - 4(1)(4) } = 0

This means there is one real solution. Since the discramnt equal 0.
