Answer:

Simplifying

2x + -10y = 15

Solving

2x + -10y = 15

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '10y' to each side of the equation.

2x + -10y + 10y = 15 + 10y

Combine like terms: -10y + 10y = 0

2x + 0 = 15 + 10y

2x = 15 + 10y

Divide each side by '2'.

x = 7.5 + 5y

Simplifying

x = 7.5 + 5yStep-by-step explanation:

You graph the function f(x)=-|×|-12

Firlakuza [10]

Answer:

See attachment

Step-by-step explanation:

We want to graph $f(x)=|x|-12$ on the interval -10 to 10.

Let $g(x)=|x|$ be the parent absolute value function.

We can easily graph $f(x)=|x|-12$ , if we use translation.

When the parent function is shifted downwards by 12 units, we obtain the graph of $f(x)=|x|-12$ .

The parent function is a v-shaped graph with vertex at the origin.

We shift the parent function down so that its vertex is now at (0,-12) to get the graph of $f(x)=|x|-12$ .

See attachment for the graph of $f(x)=|x|-12$ on the specified interval.
