F is a function. It takes inputs and then produces an output.
The notation <span>f(x)</span> is saying more specifically that the function is taking an input x and producing the output <span>f(x)</span>.
For example, if you look at <span>f(x)=<span>x2</span></span>, you can think that f is the "squaring function", with input x and outputs <span>x2</span>.
You can think that <span>"f"</span> is like the name of the function.
<span><span>f1</span>(x)=<span>x2</span></span>
<span><span>f2</span>(x)=<span>6x</span>+3</span>
Above, you know which function I'm talking about if I say <span>f2</span>. But often, people will just call it as the function <span><span><span>f2</span>(x)</span></span>
Answer:
a₉ = 11
Step-by-step explanation:
Substitute n = 9 into the nth term formula, that is
a₉ = 3(9) - 16 = 27 - 16 = 11
Answer:
Step-by-step explanation:
Since (8x-20) and (3x+2) are two sides of the angles on one plane, we can structure them into an equation to find x.
(8x-20) + (3x+2) = 180
We want x to be on one side and all the numbers to be on the other. But first, we must combine our two problems.
-20 + 2 = -18; 8x + 3x = 11x
So now our equation is:
(11x-18) = 180
In order to move our numbers to one side and leave our x's on the other, we must inverse our additions/subtractions/etc.
180 + 18 = 199
11x = 199
199/11 = 18.1
x=18.1!

To find the ratio between 2 numbers, you need to find the GCF of those 2 numbers. If the GCF is the ratio, the ratio is in it's simplest form.
GCF of 90 and 18 is 18
divide both numbers by the GCF and the final simplest ratio is 5:1
