If you move the decimal point left until it is just to the right of the most-significant digit, the number of places you moved it is the power of ten that your new number is multiplied by.

Then multiplication can proceed in the usual way, taking into account the rules of exponents.

Answer:
Answers are below
Step-by-step explanation:
3 - 7 = -4
4 - 6 = -2
3 + -6 = -3
4 - - 1 = 5
-5 + -5 = -10
-3 + 5 = 2
-4 -6 = -10
Hope this helps!!
First,we need to understand the point-slope form:

Where x and y are the coordinates and m is the slope.
Put the above information into the equation:
y-(-6)=-3/4(x-2)
y+6 = -3/4 (x-2)
Therefore the answer is C.y+6 = -3/4 (x-2).
Hope it helps!
Hello :
<span>
y=5x+8
y= -4x-1
5x+8 = -4x-1
9x =-9
x = -1
y = 5(-1)+8 = 3
