Answer:
4320 units quantities were demanded
Step-by-step explanation:
Given:
Required:
The units demanded when price = 18.00
This implies that:
So, we have:
Open bracket
Collect like terms
Solve for q
Make an equation.
80% = 0.8
'of' is multiplication
'what number' is 'x'
'is' is an equal sign
0.8 * x = 64
0.8x = 64
Divide 0.8 to both sides:
x = 80
Complex roots occur as conjugates so the other root is 3 + 2i
so we have the factored form
(x - (3 - 2i)(x - (3 + 2i)
= (x - 3 + 2i)(x - 3 - 2i)
= x^2 -3x - 2ix - 3x + 9 + 6i + 2ix - 6i- 4i^2
= x^2 -6x + 9 + 4
= x^2 - 6x + 13 Answer
Answer:
52 dimes and 54 nickels
Step-by-step explanation: 52 dimes is $5.20 and 54 nickels is $2.70
Total coins 106 total $7.90
The line would go up then stay at a constant (flat line)
