PLEASE HELP ASAP AND THANKS Find x

Mathematics
1 answer:
baherus [9]3 years ago
5 0

Answer:

The value of x is 2.

Step-by-step explanation:

First, you have to make the left side into 1 fraction by making the denorminator the same :

\frac{x}{x - 2}  +  \frac{1}{5}

=  \frac{5x}{5(x - 2)}  +  \frac{x - 2}{5(x - 2)}

=  \frac{5x + x - 2}{5(x - 2)}

=  \frac{6x - 2}{5(x - 2)}

Then you have to do cross multiplication :

\frac{6x - 2}{5(x - 2)}  =  \frac{2}{x - 2}

(6x - 2)(x - 2) = 5(2)(x - 2)

6 {x}^{2}  - 12x - 2x + 4 = 10x - 20

6 {x}^{2}  - 14x + 4 = 10x - 20

6 {x}^{2}  - 14x + 4 - 10x + 20 = 0

6 {x}^{2}  - 24x + 24 = 0

6( {x}^{2}  - 4x + 4) = 0

{x}^{2} - 4x + 4 = 0

{x}^{2} - 2x - 2x + 4 = 0

x(x - 2) - 2(x - 2) = 0

(x - 2)(x - 2) = 0

x = 2

2) simplify the expression completely assume (x > 0)
Sati [7]

Answer:

D

Step-by-step explanation:

the 2 square root terms can be combined under one large square root.

and the general multiplication factor of 2 remains on the outside.

2×sqrt(24x³ / 3x) = 2×sqrt(8x²) = 2×sqrt(4×2x²) =

2×2×sqrt(2x²) = 2×2×x×sqrt(2) = 4x sqrt(2)

The midpoint of \overline{\text{AB}}
Schach [20]

Answer:

<em>The coordinates of b are: B=(-7,-8)</em>

Step-by-step explanation:

We are given the coordinates of the midpoint of \overline{\text{AB}} as M=(-5,-2).

We are also given the coordinates of A=(-3,4). The question requires us to calculate the coordinates of the other endpoint B.

Let (xb,yb) the coordinates of B. The coordinates of the midpoint can be calculated as follows:

\displaystyle x_m=\frac{x_a+x_b}{2}

\displaystyle y_m=\frac{y_a+y_b}{2}

We know xa=-3 and xm=-5. Solve the first equation for xb:

2x_m=x_a+x_b\Rightarrow x_b=2x_m-x_a

Substituting:

x_b=2\cdot (-5)-(-3)=-10+3

x_b=-7

We can solve the second equation for xb and get:

y_b=2y_m-y_a

Since ya=4 and ym=-2, then:

y_b=2\cdot (-2)-(4)=-4-4

y_b=-8

Thus, the coordinates of b are: B=(-7,-8)
