Try dividing 160 by 5 (not by 4). Does your answer now make sense?
I'm guessing the answer is 6in.
because the original width of the photo is 8in-4in
which is 4in.
and 8 to 10 is a difference of 2
so add 2 to 4
its 6
You’re supposed to graph the function. So basically you’ll want to make it so that y=, and then the rest of your formula.
So in this case y=3x+9
We have by distributivity of limits over sums, and continuity of 
and 
, that
Given 
, it follows that
Step-by-step explanation:
5x + 2y = 10
Ax + By = C
A = 5
B = 2
C = 10
