Hey there!☺

Answer:\boxed{x=-y+7}

Explanation:

x+y=7

The first/last step we have is to add -y to both sides.

x+y+-y=7+-y\\x=-y+7

x=-y+7 is your answer.

Hope this helps!☺

Answer:

x = -y + 7

    or

x = 7 - y

Step-by-step explanation:

x + y = 7

Step 1: Subtract y from both sides to get x alone.

x + y = 7

   -y    -y

x = 7 - y

Since x is alone and y is a variable & not a number, there's nothing else to do to the equation.

What is the range of the function f(x) = |x + 4| + 2?
storchak [24]

\huge\underline{\underline{\boxed{\mathbb {SOLUTION:}}}}

<h3>Given:</h3>

▪ \longrightarrow \sf{f(x) = |x + 4| + 2}

You need to remember that the form of an Absolute Value Function is:

•<em> </em><em>For the vertex:</em>

\small\longrightarrow \sf{H= \:  \: x -coordinate}

\small\longrightarrow \sf{K= y-coordinate}

• <em>For the</em> definition:

If "a" is positive (+) , then the range of the function is:

\small\longrightarrow \sf{R:y \:   \underline >  \:  k}

If "a" is negative (-), the range of the function is:

\small\longrightarrow \sf{R: y  \: \underline  <  \: k}

In this case we can identify that:

\small\longrightarrow \sf{a = 1}

\small\longrightarrow\sf{a = 2}

\huge\underline{\underline{\boxed{\mathbb {ANSWER:}}}}

\large \bm{R: {f(x)  \in ℝ | f(x)   \underline >   2}}
