First number = X
Second number = 8X
Third number = X - 3  

The equation would be
X + (8X) + (X - 3) = 207 

X + (8X) + (X - 3) = 207

X + 8X + X - 3 = 207

10X - 3 = 207

10X = 207 + 3

10X = 210

X = 21

First number = 21
Second number = 8 * 21 = 168
Third number = 21 - 3 = 18

Suppose you set up a function to show how many hot dogs you will purchase for a dinner when you have already bought two packages
bezimeni [28]

The domain of the function is:

h > 0, only integers.

Then the correct option is the first one.

<h3>What is the domain of the given function?</h3>

For a function f(x), we define the domain as the set of the possible values of x that we can use as inputs in the given function.

Here the function is:

f(h) = 6*h + 12

Where h is the number of packages that you buy.

Then h can be only integers larger than zero (as you can't buy half a package or something like that).

Then we conclude that the correct option is the first option.

Factor Completely<br><br> 2x²-4x+6
vagabundo [1.1K]


okay well usually what I would tell you would be to use the ABC method. you would multiply A (2) by C (6) to get twelve. so you need two numbers that multiply to twelve and add to -4 (the B value). but there are no numbers that fit this description so you have to use the GCF method instead

for this method you must find the GCF for all three numbers which in this case is 2.        2(x^2-2x+3) all these numbers are now prime so this is the factored form
