What is the value of x in the equation 1/2x-3/4=3/8-5/8x?

Vladimir [108]

Answer:

x = 1

Step-by-step explanation:

1/2x - 3/4 = 3/8 - 5/8x

The LCD is 8. Lets change every fraction to a denominator of 8.

4/8x - 6/8 = 3/8 - 5/8x

Now multiply both sides by 8.

4x - 6 = 3 - 5x

Add 5x to both sides. Add 6 to both sides.

9x = 9

Divide both sides by 9.

x = 1

What is the system of inequalities associated with the following graph?

slamgirl [31]

One line passes through the points (-2,3) and (0,-3) , it means the y intercept is b=-3

and slope m = $\frac{(-3-3)}{0-(-2)}$

$= \frac{-6}{2}= -3$

So the equation of line will be $y= -3x -3$

And the inequality should be $y\geq -3x-3$

Or $3x +y \geq -3$

And the other line passes through (-2,3) and (0,2)

So the y intercept is b=2

and the slope is $m= \frac{2-3}{0-(-2)} = \frac{-1}{2}$

So the equation of line will be $y= \frac{-1}{2} x +2\\and the inequality should be y \leq \frac{-1}{2} x+2$

$2y +x \leq 4$

So answer is $3x +y \geq -3, x+2y\leq 4$
