Answer:
C - 22
Step-by-step explanation:
Put in '3 ' for 'x' in both of the equations....then multiply the results together
f(3) = 3 (3)^2 - 5 = 22
g(3) = -1
22 * -1 = -22
no it is not one x cannot have 2 y's.
About a 37% change
74 - 54 = 20
20/54 = <span>0.37037037037</span>
80% of (Cost) = $68
80% is also 0.8:
0.8 x Cost = $68
dividing each side by 0.8
Cost = 68 / 0.8 = 85 = $85
The answer is negative, because the first number is negative.
