Answer:
Gregs age is 13
Step-by-step explanation:
13 + 13 = 26
which is equivalent to 13 × 2 = 26
Answer:
x ≥ -2
Step-by-step explanation:
Divide both sides of the inequality by 2.
2x ≥ - 4
2x / 2 ≥ -4 / 2
x ≥ -2
Answer:
Consider
Amount of Rice (cups) : Amount of Water(cups)
1.2/5
2. 3/7.5=2/5
3. 5/12.5=2/5
4. 8/20=2/5
As in all cases Amount of Rice and Amount of water in cups are same.
i.e⇒ Amount of rice × K = Amount of water, where K is constant of proportionality.
So, Among all the statements
⇒ The amount of rice is the dependent value. The amount of water is the dependent value are correct.
Which means if either of them (Amount in cups) is given we can find other.
Answer:
C)x=1
Step-by-step explanation:
2x−3=−2x+1
4x−3=1
4x=4
Divide each term in 4x=4 by 4
.
4x/4=4/4
x=4/4 divide by 1
Your answer is C) x=1

Answer:
a) q = 15 at minimum average cost; q = 10 at minimum marginal cost
b) marginal cost = average cost = 225 at q = 15
Explanation:
The average cost is the total cost divided by the number of units.
A = C/q = 300 -10q +1/3q^2
The marginal cost is the derivative of the total cost.
M = 300 -20q +q^2
__
a) The minimum average cost is where its derivative is zero.
A' = 0 = -10 +2/3q ⇒ q = 15
The minimum marginal cost is where its derivative is zero.
M' = -20 +2q ⇒ q = 10
__
b) The average cost for 15 units produced is ...
A(15) = 300 -10(15) +1/3(15^2) = 225
The marginal cost at that same production level is ...
M(15) = 300 -20(15) +15^2 = 225
The average cost and marginal cost are equal at the minimum average cost.
