Can someone explain how to do this, please?​
BartSMP [9]

Answer:

\sqrt{ {28x}^{2} - 6x }

Step-by-step explanation:

You would substitute "2x" for every "x" in the function in the same way you would substitute any other number.

So if f(x)=Sqrt[7x²-3x], then: f(2x)=Sqrt[7(2x)²-3(2x)]

=Sqrt[7(4x²)-3(2x)]

=Sqrt[28x²-6x]

Which equation has a graph parallel to the graph of 9x + 3y = -22 ?<br>​
ASHA 777 [7]

Answer:

y=-3x+b

Step-by-step explanation:

To find whether or not an equation is parallel it has to have the same slope. To find this, you start by subtracting 9x from both sides, leaving you with 3y=-9x-22. Then you divide both sides by 3, leaving y=-3x-\frac{22}{3}. With this equation you can see that the slope is -3. The answer will be any equation with -3x.
