If s^2– 4s – 6 = 6, What are the possible values of s?

Mathematics
1 answer:
Effectus [21]3 years ago
5 0

Answer:

s = +6 or -2

Step-by-step explanation:

{s}^{2}  - 4s - 6 = 6

=  >  {s}^{2}  - 4s - 6 - 6 = 0

=  >  {s}^{2}  - 4s - 12 = 0

Lets factorise the eqn.

=  >  {s}^{2}  - 6s + 2s - 12 = 0

=  > s(s - 6) + 2(s - 6) = 0

=  > (s - 6)(s + 2) = 0

Here 's' will have 2 values.

1) s - 6 = 0

=  > s = 6

2) s + 2 = 0

=  > s =  - 2

If you meant:

64.3-3*(2³)/2

That would be 52.3 :)

tekilochka [14]
1.75 + 0.65m < = 10
0.65m < = 10 - 1.75
0.65m < = 8.25
m < = 8.25 / 0.65
m < = 12.69 miles <==

There are 9 performers who are to present their acts at a variety show. How many different ways are there to schedule their appe
nika2105 [10]
For this type of question it is easiest to think about it in terms of a simple multiplication. The way we can do this is by working out how many possibilities there are for each position on the program. This is as follows:
For the first act, there are 9 possible performers we can pick
For the second act, because we have already assigned a performer to the first act, there are only 8 possible performers
For the third act, because we have already assigned a performer to the first two acts, there are only 7 possible performers
This goes on and on until we reach the final act, where we have used all the performers except one.
Therefore we can say:
For the first act there are 9 possibilities
For the second act there are 8 possibilities
For the third act there are 7 possibilities
For the fourth act there are 6 possibilities and so on
If we want to write this mathematically we can just say that there are:
9 possibilities x 8 possibilites x 7 possibilities etc right down until we are at the final act where there is 1 possibility.
To write this out as an equation we just say:
9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = the number of different ways
In maths however, we have a much simpler way of saying this, which we call "factorial".
That whole stream of numbers up there can just be said to be "9 factorial", or if we are writing it in an equation "9!". You may find that your calculator has a button which has an "!" on it. If you put in the number of performers and then press the "!" button, it will give you the answer to your question.
Hope this helped you :)

What is the point slope form of the line with slope 25 that passes through the point (−4, −7)?
Arisa [49]

Answer:

Option A: y+7 = 25(x+4) is the correct answer.

Step-by-step explanation:

The point-slope form of an equation of a line is given by:

y-y_1 = m(x-x_1)

Here:

m is the slope of the line

(x_1,y_1) are the coordinates of the point from which the line passes.

Now looking at the given question:

m = 25\\(x_1,y_1) = (-4,-7)

Putting the values in the general form of point-slope form of equation of line

y-(-7) = 25\{x-(-4)\}\\y+7 = 25(x+4)

Hence, the point-slope form of given line is:

y+7 = 25(x+4)

Observing the option given, it can be concluded that Option A: y+7 = 25(x+4) is the correct answer.
