Suppose that Y varies directly with X andY equals 12 when X equals -2 what is X when Y equals -6

Mathematics

VLD [36.1K]3 years ago
4 0

Answer:

x=1

Step-by-step explanation:

A direct variation equation has the following format:

y=kx

Where k is a constant.

We know that y is 12 when x is -2. Thus, substitute:

12=-2k

Divide both sides by -2:

k=-6

So, our direct variation equations is:

y=-6x

To find what x is when y equals -6, substitute in -6 for y:

-6=-6x

Divide both sides by -6:

x=1

So, our answer is 1 :)

A new operation is defined by a△b=a^2-b/b-a^2. 4△3.
dmitriy555 [2]

As the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1

As per the question statement, we are given a new mathematical operation a△b=a^2-b/b-a^2 and we are supposed to find the value of 4△3 using the same operation.

Given, a△b=a^2-b/b-a^2

now 4△3 = (4^2-3) / (3-4^2)  

4△3 = (16-3) / (3-16)        

4△3 = 13 / -13  

4△3 = -1

Hence, as the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1.

In the accompanying diagram, parallelogram ABCD has
Taya2010 [7]

Answer:

The area of the paralellogram is 24 square units.

Step-by-step explanation:

Geometrically speaking, the area of the parallelogram has an equation equivalent to the area formula for a rectangle, that is:

A = b\cdot h (1)

Where:

A - Area.

b - Base.

h - Height.

The base and height of the parallelogram are, respectively:

Base

b = 8-2

b = 6

Height

h = 5-1

h = 4

Then, the area of the parallelogram is:

A = (6)\cdot (4)

A = 24

The area of the paralellogram is 24 square units.
