Answer:
B
Step-by-step explanation:
We can observe relationship between demand and price in the sense that, price of a commodity can influence the demand for such commodity. However, we must understand that price is usually not the only explanatory variable for demand in most cases.
Meanwhile, for this question, demand is the dependent variable because it is a function of price. That is:
==> Demand = f(Price)
And price is the independent variable.
We assume that if price of a commodity increase, the demand will decrease if there is a substitute goods in the market.
But, in a monopoly, any increase in price of the commodity might cause decrease in demand only for a while particularly if such goods is a daily necessities. This is largely due to the fact that, the consumers has no other substitute and the goods is important to their daily needs. Hence, any increase in price will rather cause economic hardship on the consumer in a monopoly market.
In conclusion, price determines demand! Thus, the situation can be described by a function. The dependent variable is the demand and the independent variable is the price.
Answer:
E
Step-by-step explanation:
-x +6 ≥ -3x - 4
Add 3x to both sides
-x + 3x + 6 ≥ -4
Combine like terms
2x + 6 ≥ -4
Subtract 6 from both side
2x ≥ -4 - 6
2x≥ -10
Divide both sides by 2
x ≥ -10/2
x ≥ -5
Inequality, in mathematics, statement that a mathematical expression is less than or greater than some other expression; an inequality is not as specific as an equation<span>equation,
in mathematics, a statement, usually written in symbols, that states the equality of two quantities or algebraic expressions, e.g., x+3=5. The quantity x
..... <span>Click the link for more information.</span> </span>, but it does contain information about the expressions involved. The symbols < (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to) are used in place of the equals sign in expressions of inequalities. As in the case of equations, inequalities can be transformed in various ways. The direction of the inequality remains unchanged if some number is added to both sides or subtracted from both sides or if both sides are multiplied or divided by some positive number; e.g., subtracting 10 from both sides of the inequality x < 8 gives x − 10 < −2, and multiplying the inequality by 2 gives 2x < 16. Multiplication or division by a negative number reverses the sign of the inequality; e.g., if −2x < 8, then dividing both sides by −2 results in the inequality x > <span>−4.</span>
Answer:
Step-by-step explanation:
- Speed = Distance/Time
- => Speed = 15 km ÷ 13/60
- => Speed = 15 km ÷ 0.216
- => Speed = 15 km/0.216
- => Speed = 15 x 4.63/0.216 x 4.63
- => Speed = 69.45 km/1 h (Approximate)
<u>Conclusion:</u>
- Therefore, the speed is 69.45 km/h (Approximate)
Hoped this helped.
