Solve for x X - 1/2 (8 - x) = x + 3(4 - x) - x<br> A) -32/9<br> B) -9/32<br> C) 32/9<br> D) 9/32

Greeley [361]

Option C

$x = \frac{32}{9}$

<em><u>Solution:</u></em>

$x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x$

We have to solve for "x"

From given,

$x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x$

Solve for brackets

Use distributive property

a(b + c) = ab + ac

Therefore,

$x - 4 + \frac{x}{2} = x + 12 - 3x - x$

Combine the constants

$x + \frac{x}{2} = x - x - 3x + 12 + 4\\\\x + \frac{x}{2} = -3x + 16$

Move the variables to left side of equation

$x + \frac{x}{2} + 3x = 16$

Combine the like terms

$2x + x + 6x = 32\\\\9x = 32\\\\x = \frac{32}{9}$

Thus option C is correct

Point M( -3, -2) is rotated 270° counterclockwise and then reflected over the x-axis. What are the coordinates of M'?

White raven [17]

Rotation involves moving a point around a center

The coordinates of M" are (-2,-3)

<h3>How to determine the coordinates of M'</h3>

The pre-image M is given as:

M =(-3,-2)

The rule of 270 degrees counterclockwise rotation is:

$(x,y) \to (y,-x)$

So, we have:

M' = (-2,3)

The rule of reflection over the x-axis is:

$(x,y) \to (x,-y)$

So, we have:

M" = (-2,-3)

Hence, the coordinates of M" are (-2,-3)
