Answer:

(2 x + 1)/(x^2 + 1)

Step-by-step explanation:

Simplify the following:

(x - 2)/(x^2 + 1) + (x + 3)/(x^2 + 1)

(x - 2)/(x^2 + 1) + (x + 3)/(x^2 + 1) = ((x + 3) + (x - 2))/(x^2 + 1):

(x + x - 2 + 3)/(x^2 + 1)

Grouping like terms, x + x - 2 + 3 = (x + x) + (-2 + 3):

((x + x) + (-2 + 3))/(x^2 + 1)

x + x = 2 x:

(2 x + (-2 + 3))/(x^2 + 1)

3 - 2 = 1:

Answer: (2 x + 1)/(x^2 + 1)

Write a linear equation based on given information. Through (5,-5) and (4,0)
Katena32 [7]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut point with the y axis

We have the following points:

(x_ {1}, y_ {1}) :( 5, -5)\\(x_ {2}, y_ {2}) :( 4,0)

We find the slope:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {0 - (- 5)} {4-5} = \frac {5} {- 1} = - 5

Thus, the equation is of the form:

y = -5x + b

We substitute a point and find b:

0 = -5 (4) + b\\0 = -20 + b\\b = 20

Finally, the equation is:

y = -5x + 20

Answer:

y = -5x + 20

Find how many solutions there are to the given equation that satisfy the given condition.
den301095 [7]

Answer:

17550 solutions

Step-by-step explanation:

Given that:

y1 +y2+y3+y4=27

where;

(yi  ≥ 0 and yi \epsilon {\displaystyle \mathbb {Z} }  )

The no. of a nonnegative integer determines the number of ways to choose 27 objects from (4) distinct objects with repetition regardless of the order.

i.e

\bigg(^{27}_{4} \bigg)

∴

The number of nonnegative integer solution is \bigg(^{27}_{4} \bigg)

= \dfrac{27!}{4!(27-4)!}

= \dfrac{27!}{4!(23)!}

= \dfrac{27\times 26\times 25\times 24 \times  23 !}{4\times 3\times 2\times 1(23)!}

= \dfrac{27\times 26\times 25\times 24 }{4\times 3\times 2\times 1}

= \dfrac{421200}{24}

= 17550 solutions

The width of a rectangular is 12 units. can the perimeter x of the rectangle can be 60 units when it's length y is 18 units
inn [45]
Yes. It's a rectangle so width*2 + length*2=perimeter
12*2=24
18*2=36
24+36=60
