Answer:
x = 2/3
Step-by-step explanation:
9x2−12x+4=0
Step 1: Factor left side of equation.
(3x−2)(3x−2)=0
Step 2: Set factors equal to 0.
3x−2=0 or 3x−2=0
x= 2
/3
2x+3+132=180
2x+135=180
subtract 135 from both sides
2x=45
divide both sides by 2
x=22.5
Answer:
Step-by-step explanation:
s + t = 544
t = 3s
substitution:
s + 3s = 544
s = 136
t = 3s = 408
Sam has 136 pieces. Todd has 408 pieces.
Solution :
a).
1. The domain of C(x)
Range of c(x) is
Since the negative value do not make any sense.
2. C(x) = Ax + b
Intercept here denotes the fixed cost (that is when x = 0)
The slope indicates the marginal cost (that is increase in cost per unit of quantity)
3. Revenue is maximum marginal revenue = 0
(that is when at the top of the parabola)
4. Profit = R(x) -C(x)
5. Range of P(x) is important so that we have the idea in mind about the maximum loss and the maximum profit for a particular quantity.
