If the lines are parallel (have the same slope but different intercepts) . . .
     no solution, because they never cross.

If the lines have different slopes . . .
     one solution, because they have exactly one common point.   

If the lines have the same slope and the same intercept . . .
     infinitely many solutions, because every point on one line is also a point on
     the other line, one lays right on top of the other, and when you look at them on
     the graph, it looks like only one line.

If z = 4.0 and y = 5.6, what is the value of x? z=y/x Express your answer to the tenths place (i.e., one digit after the decimal
liraira [26]

Answer:

x=1.4

Step-by-step explanation:

Write the equation

\frac{5.6}{x} =4

Multiply both sides by x

5.6=4x

Divide both sides by 4

1.4=x

saveliy_v [14]

Answer:

Yes

Step-by-step explanation:

Given that in the June 2007 issue, Consumer Reports also examined the relative merits of top-loading and front-loading washing machines, testing samples of several different brands of each type.

The difference in mean values test gave a p value of 0.32

Confidence level = 95%

Alpha = 1-0.95 = 0.05

Compare p with alpha, here p >alpha

Hence we accept null hypothesis that there is no difference in the means.

Confidence interval method also will yield the same result.  i.e. confidence interval for difference of means would definitely contain 0 at 95% conf level.

So answer is yes

Find the measure of the arc or angle indicated
MariettaO [177]
Short Answer: arc LM = 110°
Comment

Any two angles that have their end points on the same end points as a chord and both moving away in the same direction (in this case  down ) are equal. This is a fundamental fact about circles.

Equation
2x + 55 =  x + 55
the only way this is going to make any sense is if x = 0. No other value is possible because it will destroy the equality.

Conclusion
Both angles = 55

But that's not what you are asked for.

What you are asked for
You want to know the measure of arc LM.  
The angle connecting the center of the circle with its two arms running through the end points of the chord = the measure of  arc LM

Draw a dot where the center of the circle is and call it O. Draw in <MOL 
<MOL = 2* either of the 55° = 2 (<LKM)  = 2 * 55 = 110° That's a property of the central angle.

The measure of arc LM = 110°
