Let x and y represent the two numbers. The equation matching the word description is ...
x +4y = 25
Answer:
"yes" or "no"
Step-by-step explanation:
Answer:
Step-by-step explanation:
Equation of the line y = mx + c
The new line is perpendicular to 2x - 3y = -5
- 3y = - 5 - 2x
3y = 2x + 5
y =
Since the lines are perpendicular to each other : 
where
.
Slope of the given line

Slope of the new line

The equation to the new line passing through (-4, -3) and perpendicular to 2x - 3y = -5

Answer:
Explained
Step-by-step explanation:
This algorithm does not always give the optimal solution. There is an alternate method as well.
Consider we have to make change for 30 cents, using the least number of coins of denominations 1,10 and 25 cents.According to the given strategy, we first take a 25 cents coin and subtract it from 30 cents. Now, we have to make 5 cents which we can make only from 5 one-cent coins. So, the total number of coins required is 6 according to the given greedy strategy.
But we can simply use 3 ten-cent coins to make change of 30 cents. So, this example proves that the given strategy is not an optimal one.
