Is that .9? or was that period mark accidental?
(2x-9)^2... determine terms that are alike
40% of 3.75 is 1.50
3.75x.4=1.5
U have to substitute in the values of x to get the values of y
answers in order from left to right:
4.5, 4, 3.5, 3, 2.5, 2
ex of solving process:
x+2y=7
(-2)+2y=7
2y=9
y=4.5
Log of 0 or <0 does not exist
so x + 6 must be > 0
so the domain is (-6, +infinity)
or x > -6
