Answer:
and 
Step-by-step explanation:
Given:
The rational equation to solve is given as:

We use the cross multiplication rule and multiply the numerators one side with the denominators of the other side. Therefore,

Now, for
, the rational equation is equal to 0. So,
is a solution.
Also,
is also a solution as the equation's denominator is defined at that point.
So, no extraneous solution.
Answer:
$1.40
Step-by-step explanation:
First, 8% of $45
45*0.08=3.6
45+3.6=48.6
50-48.6=1.4
Answer:
x=2
Step-by-step explanation:
3^2x = 81
3^2x = 3^4
Compare powers
2x = 4
x = 2
we are given
point (-8,-7) for f(x)
and we have to find point for f(x-4)
we know that
whenever we have f(x-a) , we always add 'a' to x-value
so, we will add 4 units to x-value
Here , we have
x-value is -8
so,
new x-value is -8+4=-4
so, we will get
point for f(x-4) will be (-4,-7).......Answer
