Lines m and p are perpendicular. If the slope of line m is -3, what is the slope of line p?​
nika2105 [10]

Answer:      The slope of p is 1/3

Step-by-step explanation:    

If the lines are perpendicular, this means they are opposite.

Thus, O is opposite P and since O = -3, P = 1/3

1,000 POINTS!!!!!!!!! I NEED HELP ASAP
babunello [35]

Answer:

x   ≥ -4

Step-by-step explanation:

-3x + 2 ≤ 14

Subtract 2 from each side

-3x+2-2  ≤ 14-2

-3x  ≤ 12

Divide each side by -3 .  Remember that dividing by a negative flips the inequality.

-3x/-3 ≥12/-3

x   ≥ -4

Answer:

D. inverse variation; xy = 8

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

For direct variation the equation relating x and y is

y = kx, that is

k =  

Using the values in the table

= 2

=  

k is not constant hence not direct variation

For inverse variation the equation relating x and y is

y = , that is

k = xy

Using the values in the table

2 × 4 = 8

4 × 2 = 8

8 × 1 = 8

12 ×  = 8

Thus the table represents inverse variation with xy = 8

...............................................................................................................................................

Answer:

D. inverse variation; xy = 8​

Step-by-step explanation:

First we need to understand the concept of direct and inverse relation or proportion between variables.

When value of one variable increases with the increase in value of second variable, this relation is called directly proportional.

When value of one variable decreases with the increase in value of second variable, this relation is called inverse proportion.

You can observe it it daily life example too. Like if you pour water in glass, its weight will increase. If you add more water, the weight of glass will increase more. It is direct proportion. But on the other hand, if one man do any particular task in 2 hours, two men will perform task in less time, which means the hours of work are inversely proportional to number of men.

Now in given equation you can see that, when x = 2, y =4, but when x = 4, y =2, which means value of y is decreasing with the increase in value of x. So this relation is inverse.

You can also satisfy the equation by putting values of x and y.

xy = 8

From first column

2x4 = 8

From last column

12x(2/3) = 8
