Answer:

Step-by-step explanation:
So we have the equation:

And we want to solve for x. In other words, we want to isolate the x-variable.
So, add 2y to both sides of the equation.

On the left, the 2y cancel. Simplify the right:

And we're done!
Answer:
5,280 * 8 = 42,240
42,240 feet
42,240 * 12 = 506,880
506,880 inches
Step-by-step explanation:
Notation f(0) means the graph crosses y-axis where x becomes zero
or simply y-intercept
f(x) = 3 - 2x
put x = 0
f(0) = 3 - 2(0)
f(0) = 3 - 0
f(0) = 3
Special name of f(0) : <em>y-intercept</em>
Ambiguous expression. I think you meant:
3x + 7
<span>3x/(x+5)+7/(x+5) = --------------
x+5
There's no "answer." All you can do here is to combine the terms and simpify the resulting sum.
