Answer:
2x+4
Step-by-step explanation:
mx+b
goes up two then over one, best way to remember is ryse over run ! rise with a y meaning y goes on top, so technically the answer would be

the plus four is the 'b' or the y intercept so where the line crosses the vertical y.
hope this helped !
Answer:
nn
Step-by-step explanation:
Answer:
a) f g(x) = x³ - 5 x² + x -5
b) g(f(x) = x³ - 5 x² + x -5
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that f(x) = x² + 1 and g(x) = x-5
a)
f(g(x)) = f(x-5) = (x-5)²+1 = x² - 10x +25 +1 = x² - 10 x +26
<u><em>Step(ii):-</em></u>
a) f g(x) = f(x) g(x) = (x² + 1 )(x-5) = x³ - 5 x² + x -5
b) g(f(x) = g(x) f(x) = (x-5) (x²+1) = x³ - 5 x² + x -5
X-intercept: (3.5,0)
Y-intercept: (2.5,0)
Total pool = 40 by 20, or 800 feet
Recreational = 20 by 10, or 200 feet
Subtract the recreational part of the pool from the total pool, your answer should be:
600 square feet are reserved for the swim team.
