Step-by-step explanation:
(f+g)(x) means f(x) + g(x).
(f−g)(x) means f(x) − g(x).
So all you have to do is add them and subtract them.
1. (f+g)(x) = f(x) + g(x)
(f+g)(x) = (3x − 7) + (2x − 4)
(f+g)(x) = 5x − 11
2. (f−g)(x) = f(x) − g(x)
(f−g)(x) = (3x − 7) − (2x − 4)
(f−g)(x) = 3x − 7 − 2x + 4
(f−g)(x) = x − 3
3. (f+g)(x) = f(x) + g(x)
(f+g)(x) = (2x + 3) + (x² + ½ x − 7)
(f+g)(x) = x² + 2½ x − 4
4. (f−g)(x) = f(x) − g(x)
(f−g)(x) = (2x + 3) − (x² + ½ x − 7)
(f−g)(x) = 2x + 3 − x² − ½ x + 7
(f−g)(x) = -x² + 1½ x + 10
499+49.99x=y
499 is the initial cost of the computer
49.99x means you pay 49.99 per game
y is the total cost
So a palindrome is a word or number that spells the same thing forwards and backward (e.g. tacocat, racecar, 101, 262) Palindrome years occur every 110 years (except at the end of the millennium, in which it is only 11 years). The last one happened in 2002, so the next one won't occur until 2112. Maybe some of us will live to see it!
Answer:
Area= 615 ft²
Step-by-step explanation:
Apply the formula for area of a circle to find the area watered when a sprinkler covers a full circle
Area of a circle= 
r= 14ft
Area= 3.14 × 14²
Area=615.44 ft²
Area= 615 ft²
