Answer:
C - (C/100x20)
Step-by-step explanation:
Cost minus the tax
the tax is 20 percent therefore cost divided by 100 times 20
f(- 2) = 1
f(- 2) means what is the value of f(x) when x = - 2
From the table we can see that when x = - 2 f(x) = 1
Hence
Please see attached
xy-49
x x y is xy and -7x7 is 49 so the answer is xy- 49
5+7x12+75-94x347+7 2/9
