Answer:

Step-by-step explanation:

y=2x+5

5x-2=2x+5

transfer 2x to the left side and -2 to the right side you get

5x-2x=2+5

as it transfers the sign changes

3x=7

frutty [35]

No. 
It's not smaller either.
0.5  is exactly equal to  9/18 .
Both of them are different ways to write "one half".

Sylvester says that 0.000002015 written in scientific notation is 2.015 x 10 by the power of 6. Do you agree with him? Explain w
Marrrta [24]

Answer:

0.000002015 is not equal to 2.015x10^6

Step-by-step explanation:

When a power of 10 is positive the dot must be moved to the right, and when the power of 10 is negative, the dot must be moved to the left.

For example 50.000x10^3=50000 and 45.00x10^{-3}=0.045

So

2.015x10^6=2,015,000

wich is clearly not equal to 0.000002015

the correct scientific notation for 0.000002015 must be:

2.015x10^{-6}

With a negative in the power of 10, referring to a small quantity.
