Multiplying and Dividing by Powers of 10 When multiplying a number by 10, move the decimal to the right. When multiplying a numb
just olya [345]

Answer:

Because we actually divide by 10 when a number is multiplied by 0.1.

Step-by-step explanation:

Let a be a number.

When we multiply a number by 10:

a \times 10 = 10 a (One '0' is increased in the number)

For example:

23 \times 10 = 230

Considering a decimal number:

2.3 \times 10 = 23

Multiplying a number with 0.1 (which is actually \frac{1}{10}) means dividing the number by 10.

23\times 0.1 =23\times \frac{1}{10}=2.3

Considering a decimal number:

2.3 \times 0.1 = 2.3 \times \frac{1}{10} = 0.23

<em>Therefore, When multiplying a number by 0.1, move the decimal to the left.</em>

I need help with slope (8th grade)
Triss [41]

Answer:

(y1-y2)/(x1-x2)

Step-by-step explanation:

if you have two points from the graph then you can use them to find the slope, for example:

(2,3) and (0,5)

you would take the first point and put it in a fraction (and the second point) but the x goes on the bottom and the y goes on the top:

3/2 and 5/0

Next you put them together minusing one of the equations, but make sure that the two coordinates line up (it doesn't matter which one, in the order):

3-5/2-0

Then you solve:

-2/2

-1

which means that -1 is the slope for this

(the "/" is a fraction bar, in case you didn't already know that)
