You can use substitution for this.
x+5 = 5x -11
Combine like terms
16=4x
Divide 4 on both sides to isolate the x
x=4
Plug x=4 to one of the equations
y= 4 +5
Combine like terms
y=9
So the answer is A. (4,9)

Answer: Log (a^2c/ b^3 d^4)
Standard form for the equation of the line is

Solution:
Given point is (2, –5).
slope of the line m = 
Here, 
Equation of a line passing through the point:




Subtract 15 from both sides of the equation.


Standard form for the equation of the line is

Answer:
You must survey 784 air passengers.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error is:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
Assume that nothing is known about the percentage of passengers who prefer aisle seats.
This means that
, which is when the largest sample size will be needed.
Within 3.5 percentage points of the true population percentage.
We have to find n for which M = 0.035. So






You must survey 784 air passengers.
