Answer:

f(5, 0) = 25

f(5, -3) = 61

Step-by-step explanation:

f(x, y) = x² - 3xy - y²

⇒ f(5, 0) = (5)² - 3(5)(0) - (0)²

= 25 - 0 - 0

= 25

⇒ f(5, -3) = (5)² - 3(5)(-3) - (-3)²

= 25 - 15(-3) - 9

= 25 + 45 - 9

= 61

three friends earned more than $200 washing cars. they paid their parents $28 for supplies and divided the rest of money equally

Flura [38]

28x+86≤200 because for supplies they divide the rest of money. that means, 200-28=172 so 172/2=86 now we gonna find the value of x.
28x+86≤200 i am gonna subtract 86 both of side 28x+86-86≤200-86 to get value of x.
28x≤114 divide 28 both of side to get value of x so it will be x≤4
