Line M is represented by the equation -2/3+8. Line W is perpendicular and passes through the point (4,3)
goblinko [34]

Answer:

y= -3/2x+9

Step-by-step explanation:

Well we have to know that to find a line perpendicular to a given line, you have to have opposite slopes. So that makes the equation begin as y=-3/2x because it's opposite of y=2/3x. Then we have to make sure it goes through the point (4,3). To do that, I tweaked the numbers in my graphing calculator and it worked with 9! So the equation is y= -3/2x+9

morpeh [17]
If we have the speed of 18 miles per second, 18miles/s
to find out what is the speed in 1 minute we will need to multiply 18 by 60, as there are 60 seconds in 1 minute
18 miles..............................1 second
?miles..................................60 seconds(1min)
18*60=1080 miles
we have 1080 miles/minute
in 2 minutes we have 1080*2=2160 miles

Herbert has sold 90, 45, 103 and 68 appliances in the last four months, respectively. How many appliances will he need to sell t
Elena-2011 [213]

Answer:

The sale this month = 79

Step-by-step explanation:

Let the amount he needs to sell this month = x

Average = \frac{sum\ of\ individual\ data\ }{number\ of\ entries}

Average= \frac{90\ +\ 45\ +\ 103\ +\ 68\ +\ x}{5}

Note that number of entries = number of months = 5

To maintain an average sales of 77, the amount of sale in month 5 is determined as follows:

77 = \frac{306\ +\ x}{5} \\cross-multiplying\\77\ \times\ 5\ = 306\ +\ x\\385 = 306\ +\ x\\x =385\ -\ 306\\x = 79
