1+1=3 proof<br> needs step by step explanation
Vsevolod [243]

Answer:

1+1=3, See explenation

Step-by-step explanation:

1+1=2 but thats basically 2.1 because whole numbers are boring, but 2.1 is basically 2.2 because we want it as an even number, but 2.2 is basically 2.3 because 2.3 is the luckiest number, which is basically 2.5 if you think about it because 2.3 looks like 2/3 and two thirds can't be a whole (which is why we say 3/3 instead of 2/3) and 2.5 rounded up is 3. So thats how 1+1=3

What are the coordinates of J'?
attashe74 [19]

Answer:

F'(-\frac{10}{3},-\frac{8}{3})

or

F'(-3.33,-2.67)

Step-by-step explanation:

we know that

The coordinates of point F are (-5,-4) (see the figure)

In this problem

A dilation with a scale factor 2/3 about the origin is described using the following notation:

(x,y) ----> (\frac{2}{3}x,\frac{2}{3}y)

so

Applying the rule of the dilation to point F

F(-5,-4) ----> F'(\frac{2}{3}(-5),\frac{2}{3}(-4))

F(-5,-4) ----> F'(-\frac{10}{3},-\frac{8}{3})

F(-5,-4) ----> F'(-3.33,-2.67)
