Evaluate 1 plus negative 2/3 minus (-m) where m is 9/2

Mariana [72]

Answer:

Step-by-step explanation:

Negative 2/3 means -2/3

Hence;

1 + (-2/3) - (-m)

= 1 - 2/3 + m (positive x negative = negative, negative x negative = positive)

Substituting 9/2 for the value of m

= 1 - 2/3 + 9/2

The L.C.M = 6

= ( 6 - 4 + 27)/6

= 29/6

67. The line contains the point (4,0) and is parallel to the line defined by 3x = 2y.

olganol [36]

Answer:

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

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form:

$y=mx+b$ where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)

Parallel lines will always have the same slope but different y-intercepts.

1) Determine the slope of the parallel line

Organize 3x = 2y into slope-intercept form. Why? So we can easily identify the slope, m.

$3x = 2y$

Switch the sides

$2y=3x$

Divide both sides by 2 to isolate y

$\frac{2y}{2} = \frac{3}{2} x\\y=\frac{3}{2} x$

Now that this equation is in slope-intercept form, we can easily identify that $\frac{3}{2}$ is in the place of m. Therefore, because parallel lines have the same slope, the parallel line we're solving for now will also have the slope $\frac{3}{2}$ . Plug this into $y=mx+b$ :
