Answer:
The answer to the question is
Shawn has to wait for 3 minutes for Jason to meet him at 2 miles away from the station
Step-by-step explanation:
To solve the question, we note the variables
Bike speed = 20 mph
Start point of Jason = 1 mile away from the station
Starting point of Shawn = 2 mile away from the station
Total miles away from station = y
Direction of biking = away from the station
Therefore if they both start biking at the same time, Shawn is ahead of Jason
Riding speed of Shawn = Riding speed of Jason = 20 mph
That is Shawn has to wait for 1/20 hr or 3 minutes for Jason to meet him at 2 miles away from the station
Answer:
The correct answer is
Step-by-step explanation:
Method 1
We want to simplify,
The double negatives becomes positive,
We now add the whole number parts and the fractions separately
This will give us,
The least common denominator for the fractional parts is 9.
Method 2
We want to simplify,
The double negatives becomes positive,
We first convert the mixed numbers to improper fractions to obtain,
We carry out the multiplication in the numerator to get,
We add in the numerator to get,
The least common denominator is .
We convert back to mixed numbers to get,
Answer:
34
Explanation:
When 68 is decreased by 50%, that would mean that it is decreasing by half of that number. Half of that number would be 34 and that would be your answer.
Answer:
(f + g)(x) = 12x² + 16x + 9 ⇒ 3rd answer
Step-by-step explanation:
* Lets explain how to solve the problem
- We can add and subtract two function by adding and subtracting their
like terms
Ex: If f(x) = 2x + 3 and g(x) = 5 - 7x, then
(f + g)(x) = 2x + 3 + 5 - 7x = 8 - 5x
(f - g)(x) = 2x + 3 - (5 - 7x) = 2x + 3 - 5 + 7x = 9x - 2
* Lets solve the problem
∵ f(x) = 12x² + 7x + 2
∵ g(x) = 9x + 7
- To find (f + g)(x) add their like terms
∴ (f + g)(x) = (12x² + 7x + 2) + (9x + 7)
∵ 7x and 9x are like terms
∵ 2 and 7 are like terms
∴ (f + g)(x) = 12x² + (7x + 9x) + (2 + 7)
∴ (f + g)(x) = 12x² + 16x + 9
* (f + g)(x) = 12x² + 16x + 9
