The answer is that y is equal to -3 and x is equal to 7 
2x-y=17
-2(x-y)=10 )
--------------
2x-y=17
-2x+2y=-20
----------------
y=-3

x-y=10 
x-(-3)=10
x+3=10

What does y= 4x+rx+6 equal? (Solve for x)
Tems11 [23]
Minus 6 both sides
y-6=4x+rx
undistribute x
y-6=x(4+r)
dividie both sides by (4+r)
\frac{y-6}{4+r}=x
x=\frac{y-6}{r+4}

Graph the function f( x ) = |x+2| - 3
stepladder [879]

Answer:

Find the attached

Step-by-step explanation:

To graph the given function, we would need to obtain pairs of points (x, f(x)). We can let x be;

-5, -4, -3, 3, 4, 5

we simply substitute each value of x in the given function to obtain the value of the function corresponding to the given x value;

when x = -5, f(-5) =  |-5+2| - 3 = 0

when x = -4, f(-4) =  |-4+2| - 3 = -1

when x = -3, f(-3) =  |-3+2| - 3 = -2

when x = 3, f(3) =  |3+2| - 3 = 2

when x = 4, f(4) =  |4+2| - 3 = 3

when x = 5, f(5) =  |5+2| - 3 = 4

The graph of the function is as shown in the attachment below.

The graph shows how the volume, V, of the cube changes as the length of the sides, S, changes
Artemon [7]

Solution:

The graph shows how the volume, V, of the cube changes as the length of the sides, S, changes.

On analysing the graph ,

\left\begin{array}{ccc}s&v\\0&0\\2&1\\4 &8\end{array}\right

This table shows how the volume, V, of the cube changes as the length of the sides, S, changes.

Option C is the correct option for the table that matches the graph.
