One way to solve this system of equations would be by substitution. It would helpful to write these equation in the form y=mx + b in order to substitute one equation to the other. We do as follows:

<span>1.) x - 2y = 6
y = x/2 -3

2.) 2x - 4y = 10
y = x/2 - 5/2

As we look at the rearranged equations, we see that their slopes are equal which means they are parallel lines so they do not intersect at one point. There is no solution for this system of equations.</span>

List the coordinates for the plotted points A, B, C, and D.
avanturin [10]

Answer:

A= (3,1) ; B=(-2,-1) ; C=(-4,1) ; D=(-4,0)

Step-by-step explanation:

Plotted points are expressed by (x,y) , where the x is equal to the value that you read on the x plot and y is equal to the value that you read on the y plot.

A student walked 100 meters north, then 100 meters west. how many more meters did the student walk compared to their total displ
seraphim [82]

Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.

If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).

Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.

c^2 = a^2 + b^2

where c is the total displacement from the starting point to the end point

a is the distance he walks up north

b is the distance he walks to the west

c^2 = 100^2 + 100^2

c^2 = 10,000 + 10,000

c^2 = 20,000

c = 141.42 meters

Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.

100 meters + 100 meters - 141.42 meters = 53.58 meters

a laboratory, you determine that the density of a certain solid is 5.23×10−6kg/mm3. Convert this density into kilograms per cubi
Vedmedyk [2.9K]

Answer:

5.23\times 10^{-6}\ kg/mm^3=5230\ kg/m^3          

Step-by-step explanation:

Given : The density of a certain solid is 5.23\times 10^{-6} kg/mm³.

To find : Convert this density into kilograms per cubic meter ?

Solution :

We know that,

1\ m^3=10^9\ mm^3

or 10^9\ mm^3=1\ m^3

So, 1 mm^3=\frac{1}{10^9}\ m^3

1 mm^3=10^{-9}\ m^3

Converting 5.23\times 10^{-6} kg/mm³ into kg/m³,

5.23\times 10^{-6}\ kg/mm^3=\frac{5.23\times 10^{-6}}{10^{-9}}\ kg/m^3

5.23\times 10^{-6}\ kg/mm^3=5.23\times 10^{-6+9}\ kg/m^3

5.23\times 10^{-6}\ kg/mm^3=5.23\times 10^{3}\ kg/m^3

5.23\times 10^{-6}\ kg/mm^3=5230\ kg/m^3

Therefore, 5.23\times 10^{-6}\ kg/mm^3=5230\ kg/m^3
