Answer:
3m² + 7m - 6
Step-by-step explanation:
2m (3/2m + 1) + 3(5/3m - 2)
(3m² + 2m) + (5m - 6)
3m² + 2m + 5m - 6
3m² + 7m - 6
In polynomials, when a term contains both a number and a variable part, the number is called the co-efficient.
In this problem the co-efficient of x =
(8+y)+(3x+y2)
3y+3x+8
Therefore the co efficient of x and y is 3
<h3>
Answer: 144 Joules </h3>
Steps Shown:
Work = Force * Displacement
Work = (36 Newtons)*(4 meters)
Work = (36*4) Newton meters
Work = 144 Newton meters
Work = 144 Joules
Note: The displacement must point in the same direction as the force applied.
Answer:
Step-by-step explanation:
We have been given that a discount store’s prices are 25% lower than department store prices. The function represents the cost (c), in dollars, of an item, where x is the department store price, in dollars.
We are also told that when the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. The function represents d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars.
We are supposed to find the function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month.
We can see that function d(c(x)) is a composite function. To get our composite function we just need to substitute function c(x) in function d(y).
After making the substitution we will get our desired function as,
Upon simplifying our function will be:
Therefore, the function represents the final price of an item when a costumer buys an item that has been in the discount store for a month.
Part A: 42.50+0.65x<60
Part B: You can enjoy maximum 26 rides at the fairy tale spectacular.
Step-by-step explanation:
Given,
Admission cost to fair = $42.50
Cost of each ride = $0.65
Amount you can spend = $60
Let,
x be the number of rides you can take.
Admission fair + Cost of each ride*number of rides < Amount you can spend
Part A: write an inequality that represents this situation.
42.50+0.65x<60
Part B: solve the inequality to determine the maximum number of rides you can enjoy at the fairy tale spectacular.
Dividing both sides by 0.65
Rounding off to nearest whole number;
x<27
Less than 27 means, you cannot take 27 rides, therefore,
You can enjoy maximum 26 rides at the fairy tale spectacular.
