You would move it between the 4 and 8 because you only moved the decimal place one place to the right with the divisor. You would move it the same amount with the dividend to make it 34.84 divided by 51.
Factoring the expression would be 6a(2a^2+4a-1)
Answer:
Step-by-step explanation:
In order to do this we need to isolate y by performing the inverse operations on the other values like so...
a) 10x + 5y = 20 ... subtract 10x on both sides
5y = 20 - 10x ... divide both sides by 5
y = 4 - 2x ... we can move the 2x to the right to make it into y = mx + b
y = -2x + 4
b) 3x - 2y = 10 + 4x ... subtract 3x on both sides
-2y = 10 + x ... divide both sides by -2
y = -5 - 0.5x ... move -0.5 to the left so it matches y = mx + b
y = -0.5x - 5
If the slope formula is

all you have to do is plug in the points:

=

=

or

=

Either way your slope is going to be
