Usually you will see something like g(x) or f(x)
domain means all the x's
so, think of g(4) meaning g(x=4) and g(4 in the domain).
look for 4 on the domain side
you know that f(x) = y
range means all the y's
so its basically saying, look on the domain side for 4 and see what comes out (or =) on the range side.
in this case, it's B) 5
What you need to do is to find a multiple of 20 and 16 in other words a number that can multiply into 20 and 16. You have 2 and you have 4. So now this is how it looks like.
Either:
4(5+4) Or
2(10+8)
Answer:
x = -1.4
Step-by-step explanation:
Subtract the right side and simplify.
5 - 6(2 - x) - (x - 14) = 0
5 - 12 + 6x - x + 14 = 0 . . . . parentheses eliminated
7 + 5x = 0 . . . . . . . . . . . . . . terms collected
1.4 + x = 0 . . . . . . . . . . . . . . divide by 5
x = -1.4 . . . . . . . . . . . . . . . . . add the opposite of the constant
_____
Check
5 -6(2 -(-1.4)) = (-1.4) -14
5 - 6(3.4) = -15.4
5 -20.4 = -15.4 . . . . . true. Answer checks OK.
