Find the equation of the line through the point (-2,-2) that is perpendicular to the line y=2x-1

Lerok [7]

A line perpendicular to y = 2x - 1 must have the slope -1/2 (negative reciprocal of 2).

Thus, the eq'n of the new line is y+2 = (-1/2)(x+2).

Answer:

a) 7/5

Step-by-step explanation:

$y-\frac{y-1}{2}=1-\frac{y-2}{3} \\Through\ the\ butterfly\ method\ of\ resolving\ denominators\ ,\\\frac{2y-(y-1)}{2} = \frac{3-(y-2)}{3} \\\frac{2y-y+1}{2} = \frac{3-y+2}{3} \\\frac{y+1}{2} =\frac{5-y}{3} \\3(y+1)=2(5-y)\\3y+3=10-2y\\3y+2y=10-3\\5y=7\\y=\frac{7}{5}$

The population of a city was 572,000 in 2010. In the 2000 census the population was 607,000. What was the rate of decrease of th

kramer

Answer:

Step-by-step explanation:

<em>To solve this you need to subtract 607000 by 572000 to see how many people in the population decreased.</em>

607,000- 572,000= 35,000

Then you put 35,000 over 607,000

also you need x over 100

35000/607,000 x/100

Then do cross product property

35,000*100=3,500,000

607,000* x= 607,000x

3,500,000= 607,000x

Then do 3,500,000 divided by 607,000

You get 5.76%

Round to the nearest percent and get 6%
