What is the equation of the line perpendicular to 3x+4y=12 and containing the point (6,-2)
tester [92]

3x+4y=12

4y = - 3x + 12

 y = -3/4 x + 3; This line has slope equal - 3/4

Perpendicular lines, slope is opposite and reciprocal so slope of new line = 4/3

Passing point (6 , -2)

y + 2 = 4/3(x - 6)

y + 2 = 4/3 x - 8

y = 4/3 x - 10

Answer

Equation: y = 4/3 x - 10

Liula [17]

Answer:

The answer is C. Depression.

Step-by-step explanation:

Depression is defined as a severe and prolonged recession. Declining economic activity is characterized by falling output and employment levels. Generally, when an economy continues to suffer recession for two or more quarters, it is called depression.

The level of productivity in an economy falls significantly during a depression. Both the GDP (gross domestic product) and GNP (gross national product) show a negative growth along with greater business failures and unemployment. Depressions are relatively less frequent than milder recessions, and tend to be accompanied by high unemployment and low inflation.

About 2% of the population has a particular genetic mutation. 600 people are randomly selected. find the standard deviation for
AnnyKZ [126]
The standard deviation is 0.4801.

To find the standard deviation we use the formula:

s = √n(p)(1-p), where n is the sample size and p is the probability.

Using this, we have:
s = √600(0.02)(1-0.02) = √600(0.02)(0.98) = 0.4801.

Mari,Carlos, and Amanda all collect stamps. Carlos has five more stamps then Mari, and Amanda has three times as many stamps as
MArishka [77]
Let the amount of stamps Mari has be “m”. Since Carlos has 5 more stamps than Mari, Carlos will have 5+m stamps. Amanda has three times as many stamps as Carlos so that will be 3(5+m)=15+3m.
m+(5+m)+(15+3m)=100
5m+20=100
5m=80
m=16
Mari=16
Carlos=16+5=21
Amanda=15+48=63
