Hi there!

We can begin by making each fraction have a common denominator:
If we make each have a common denominator of ab, we get:

Simplify:

Multiply both sides by ab:

Move b to the opposite side:

Factor out b:

Divide by (ac - 1):

Answer:
Because she is concluding that her class is an accurate representation of the overall school. The sample size in this case is too small and should increase her sample size(the amount of people surveyed) in order to get a better result.
Answer:
295
Step-by-step explanation:
Answer:
12^4 = 20736
Step-by-step explanation:
The property of exponents used to simplify : 12^8/12^4
The division property :
a^x / a^y = a^(x - y)
Therefore ;
12^8/12^4
12^8 / 12^4 = 12^(8 - 4) = 12^4 = 20,736
The y-intercept would elevate up the y-axis by 3
This is because the y-intercept in y= -4x+2 is 2 and when you change it to y= -4x+5 you are moving the intercept to a y of 5.
