This equation has no solution.
A a non-zero constant never equals zero.
Equation of a Straight Line
 2.2     Solve   2x-5y-5  = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  2x-5y-5  = 0 and calculate its properties
 
        
             
        
        
        
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
, and a confidence level of  , we have the following confidence interval of proportions.
, 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
, z is the value of Z that has a pvalue of  , so
, 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.
, 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.
 
        
             
        
        
        
So 4 6/8= (32/4)+6/8=38/8
11 1/3=(33/3)+1/3=34/3
so 38/8+(34/3)
to add you must get the bottom number equall so
114/24+272/24=386/24=16 1/12

Answer:
 length: 16 m; width: 13 m
Step-by-step explanation:
Write each of the statements as an equation. You know that the formula for the perimeter is ...
 P = 2(L +W)
so one of your equations is this one with the value of P filled in:
 • 2L + 2W = 58
The other equation expresses the relation between L and W:
 • L = W +3 . . . . . . . . the length is 3 meters greater than the width
There are many ways to solve such a system of equations. Since you have an expression for L, it is convenient to substitute that into the first equation to get ...
 2(W+3) +2W = 58
 4W +6 = 58 . . . . . . . simplify
 4W = 52 . . . . . . . . . . subtract 6
 W = 13 . . . . . . . . . . . .divide by 4
We can use the expression for L to find its value:
 L = 13 +3 = 16
The length is 16 meters; the width is 13 meters.
