Answer:

x=8.

Step-by-step explanation:

You can remove the parenthesis by multiplying the 3 to everything in them. In this case, it would be 3x-15=9. You can start by adding 15 to both sides, which give us 3x=24. You can now divide 3 by both sides. The right side is 24/3 which is 8 and the left side is just x. x=8.

It's linear

If you evaluate x when it's 0 you'll get the cut in y, that means the function will pass on (0,7)

The formula for linear functions is y=mx +b

In this case b is 7

M=7-5/0+1

M=2

Now you just write the function down, it would be

F(x) =2x + 7

What is 321.5 Kilometers per hour converted to MPH
inessss [21]
321.5\ kmph\approx\boxed{199.770777\ mph}

By the way, Google has a built in calculator. You can just type in "321.5 kmph in mph" and it will come up with this answer.

You could also use the fact that 1\ km\approx0.621371\ mi,
According to the properties of equality, if you have two equal expressions and you change them in the same way, the results wil also be equal.
So that means we can multiply each side by 321.5 and get our answer above.
