Answer:
f(1) - 1 = -3
Step-by-step explanation:
Step 1: Find f(1)
f(1) = -3(1) + 1
f(1) = -3 + 1
f(1) = -2
Step 2: Find f(1) - 1
f(1) - 1 = -2 - 1
f(1) - 1 = -3
1) Lets say there is point A that is perpendicular to WX and has W in it.
2) To find YA, we have to 19 - 11 = 8
3) Do Pythagorean theorem to find WY, which is:

This is equal to
42.76 in decimal
First you will have too find the least common multiple which is 20 and what you multiplied to get 20 multiply it which will make 3/5 to 12/20 and 1/4 too 4/20 and then subtract the two which is 8/20 or 8 oranges. if you need more information talk too me
3/6
because 6 divided by 2 = 3
and
12 divided by 2 = 6
