Answer:

Both expressions equal 5 when substituting 2 for x because both expressions are equivalent

Step-by-step explanation:

Given

$\frac{1}{2}x + 4$ - Expression 1

$x + 6 - \frac{1}{2}x - 2$ -- - Expression 2

Required

Find the result of both expressions when $x = 2$

<em>Expression 1</em>

$\frac{1}{2}x + 4$

Substitute $x = 2$

$\frac{1}{2} * 2 + 4$

$1 + 4$

$Result = 5$

<em>Expression 2</em>

$x + 6 - \frac{1}{2}x - 2$

Substitute $x = 2$

$2 + 6 - \frac{1}{2} * 2 - 2$

$2 + 6 -1 -2$

$Result = 5$

The image of the point (7,-4) under a translation is (12,-5). Find the coordinates

Afina-wow [57]

The translation is right 5, down 1, AKA (x+5, y-1). The original coordinate of the point given is (-8,-3). Use the same translation so ((-8 + 5), (-3 - 1)) = (-3,-4)
