The answer is 400.000+ 10.000+ 2.000+ .600+ .030+ .008

I came to this conclusion because I took each number and replaced all of the other numbers with the place holder "0".

-8x/5+1/6=-5x/3 I don't get how to find the answer?
NeX [460]
In order to find this answer we have to manipulate the equation algebraically so that we end up with a statement that x = something. We can manipulate the problem however we need to as long as we do the same thing to both sides of the equation (this keeps the equation true).

-8x/5 + 1/6 = -5x/3

first lets get the x's on one side of the equals sign by adding 8x/5 to each side.

1/6 = -5x/3 + 8x/5

Ok, now let's add the x's together (we need common denominators)

1/6 = -25x/15 + 24x/15
1/6 = -x/15

Now lets get x by itself by multiplying each side by 15

1/6 * 15 = -x
15/6 = -x
3/2 = -x

Multiply each side by -1 to make the x positive.

-3/2 = x

What is the image of (2,3)(2,3) after a reflection over the line y=-xy=−x?
otez555 [7]

Answer:

After the reflection over the line  y = -x, the image of the point is: (-3,-2)

Step-by-step explanation:

When a given point is reflected over a line the point only changes place but the distance between the point and the line remains same.

Let (x,y) be a point on the plane

and

y = -x be a line on the plane

When a point is reflected over a line y = -x , the coordinates of the point are exchanged which means x becomes y and y becomes x and both are negated

So (x,y) will become (-y,-x)

Given point is:

(2,3)

After the reflection over the line  y = -x, the image of the point is: (-3,-2)
