1,200 because 4x 3 is 12 and 40 x 30=1,200
F(g(x)) means u solve g(x) first then you plug that value into f(x)
x = -1
g(-1) = -1 + 3 = 2
plug 2 into f(x)
f(2) = 5(2) - 10 = 0
Step-by-step explanation:
- A. linear equation
- D. None of the above
- B. Boundary line Broken line
- A solid line
- 6.sorry
V=length times width times height
wait, we need it in yards
3ft=1yard
so height=1
v=45 times 30 times 1
v=1350 cubic yards
1 cubic yard=201.974 gallons
so times both sides by 1350
272664.9 gallons
per every 5000 gallons of water we have 1 of chlorine
so 272664.9/5000=54.53298
so we need about 54.5 gallons or 55 gallons of cholrine
