Answer:
First choice is the correct one

Explanation:
The given is:
[(x+5) / (x+2)] - [(x+1) / x(x+2)]
First, we will need to have a common denominator and then we will solve the subtraction normally. To get a common denominator, we will have to multiply both numerator and denominator of first term by x.

Therefore:
[(x+5) / (x+2)] - [(x+1) / x(x+2)] = [x(x+5) / x(x+2)] - [(x+1) / x(x+2)]
                                                 = [x(x+5)-(x+1)] / [x(x+2)]
                                                 = (x^2 + 5x - x - 1) / [x(x+2)]
                                                 = [(x^2 + 4x - 1)] / [x(x+2)]

Hope this helps :)

Simplify completely x^2+4x-5/5x^2-8x+3
arlik [135]

Answer:

\boxed{\bold{\frac{x+5}{5x-3}}}

Explanation:

[ Step One ] Factor \bold{x^2+4x-5}

\bold{x\left(x-1\right)+5\left(x-1\right)}

[ Step Two ] Rewrite Equation

\bold{\frac{\left(x-1\right)\left(x+5\right)}{5x^2-8x+3}}

[ Step Three ] Factor \bold{5x^2-8x+3}

\bold{\left(x-1\right)\left(x+5\right)}

[ Step Four ] Rewrite Equation

\bold{\frac{\left(x-1\right)\left(x+5\right)}{\left(5x-3\right)\left(x-1\right)}}

[ Step Five ] Cancel Out Common Factor \bold{x-1}

\bold{\frac{x+5}{5x-3}}

\boxed{\bold{Mordancy}}

Y=-2 y=3x+1 in graph
Airida [17]

Answer:

The solution of the system is x=-1, y=-2

Step-by-step explanation:

we have

y=-2 ----> equation A

y=3x+1 ----> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both lines

using a graphing tool

The intersection point is (-1,-2)

see the attached figure

therefore

The solution of the system is x=-1, y=-2
