Answer:

The minimum number of nickels that she could have is 15

Step-by-step explanation:

Let x represent the number of nickels Ashley has. If she has 4 pennies and has at most 22 coins, then

→ x + 4 <= 22

→ x <= 18    (1)

Her coins worth a minimum $0.78. Also, it is known that 1 dollar is equal to 100 cents and 1 nickel is equal to 5 cents.

→ (x * 5) + 4 >= 78

→ 5x >= 74

→ x >= 14.8  (2)

If we combine the equation 1 and 2:

14.8 <= x <= 18

The minimum value of x is 15

Answer:

18 nickels

Step-by-step explanation:

4 pennies = $0.04. 22 coins minus the 4 pennies = 18. So, 18 nickels is equal to $0.90. Because she has at most 22 coins and they're worth at least $0.78 then $0.94 would make since.

C = 5/9(F - 32)

C = 5/9(F) - 17.777

-5/9(F) + C = -17.777

-5/9(F) = -C - 17.777

F = 5/9(C) + 32.0306

Mrac [35]

Answer:

9 square units

Step-by-step explanation:

f(x) = -(x - 3)² + 9

= 9 -(x - 3)²

9 minus something, the result is always less than 9, at most equal to 9.

So the maximum f is 9 square units
