Line them up by the decimal point
Answer:
42
Step-by-step explanation:
We know that 10x + 6y = 7, and so
6(10x + 6y) = 6(7) = 42
Lemme post a quick template of some help



so f(x) - k, is simply appending a constant "k", and thus is a vertical shift by
k units.
f(x+h) is changing whatever "x" was to "x+h", and therefore is shifting the function to the left by
h units.
f(x-h), is about the same as before, but is doing a horizontal shift to the right by
h units.
4 bags * 1 =$4
2 cans *2 = $4
milk = $3
3 bread *3 =$9
