Write the slope-intercept form of the equation of the line that passes thrqugh (-4, -3) and is
Zielflug [23.3K]

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 =\frac{2x}{3} + \frac{5}{3}

Since the lines are perpendicular to each other : m_{1} . m_{2} = -1

where m_{1} \ slope \ of \ the \  given  \ line  \ and  \ m_{2} \  slope \ of \ the  \ new  \line\\.

Slope of the given line

                m_{1} = \frac{2}{3}

Slope of the new line

                \\\frac{2}{3}.m_{2} = -1\\  m_{2} = -1 . \frac{3}{2}   = \frac{-3}{2}

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

                            (y - y_{1}) = m_{2}(x-x_{2} )\\\\(y - (-4)) = \frac{-3}{2}(x - (-3)) \\\\(y + 4) = \frac{-3}{2} (x+ 3)\\\\2(y +4) = -3(x+3)\\\\2y + 8 = -3x -9 \\\\2y = -3x - 9 -8\\\\y = \frac{-3x}{2} - \frac{17}{2}

Suppose we need to make change for n cents, and we want to use the least number of coins of denominations 1, 10, and 25 cents. C
frutty [35]

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.
