Step-by-step explanation:

Formula for slope is m = y2 - y1 /x2 - x1

you will then use 7-8/4-5

Then -1/-1 which will simplify to 1

Evaluate: a) n!/(n-3)!<br>b) P(6,4)/4!

telo118 [61]

Step-by-step explanation:

a).

n! is

$n(n - 1)(n - 2)(n - 3)(n - 4).........(1)$

(n-3)! is

$(n - 3)(n - 4)(n - 5)..........(1)$

If we divide the two, everything behind (n-3) will just cancel out so we would be left with only

$(n)(n - 1)(n - 2)$

So the answer to a is

$n(n - 1)(n - 2)$

Permutations formula of P(6,4) is

6!/(6-4)!, or 6!/2!.

$\frac{6 \times 5 \times 4 \times 3 \times 2 \times 1}{2 \times 1} = 360$

Then we divide by 4!

$\frac{360}{4 \times 3 \times 2 \times 1} = 15$

The answer to b is 15

A rectangle has a length that is 5 inches greater than its width, and its area is 104 square inches. The equation (x + 5)x = 104

Art [367]

Answer:

The answer is 8.

Step-by-step explanation:

We need to use the quadratic formula, that is ax2+bx+c=0

Where

$x=\frac{-b +/- \sqrt{b^{2}-4*a*c } }{2a}$

For the given equation x2+5x-104=0 we have

a=1, b=5, c= -104

If you solve that, we will have x=-13. x=8, two answers,

The first one, by being negative does not have physical sense (there are no negatives quantities when you measure the length of something)

So we use the anwser x=8
