Answer:
Step-by-step explanation:
f(x) = 3x² - 3x
g(x) = -5x + 4
Find the value of the function when x = -3:
f(x) = 3x² - 3x
f(-3) = 3(-3)² - 3(-3)
f(-3) = 3(9) + 9
f(-3) = 27 + 9
f(-3) = 36
Find the value of the function when x = 5:
g(x) = -5x + 4
g(5) = -5(5) + 4
g(5) = -25 + 4
g(5) = -21

Answer:
($20/gal)r + ($30/gal)b ≤ $250
r + b ≤ 10 (gallons)
Step-by-step explanation:
Represent the amount of red paint by r and that of blue point by b.
Olivia must cover 5000 ft^2 with paint, which comes out to 5000/500, or 10, gallons total of red and blue paint. The corresponding inequality is
r + b ≤ 10 (gallons)
She has onlyl $250 to spend. Therefore, the following must hold true:
($20/gal)r + ($30/gal)b ≤ $250
The required sysstem of inequalities is thus
($20/gal)r + ($30/gal)b ≤ $250
r + b ≤ 10 (gallons)
