How many solutions does the system 2y=10x-14 and 5x-y=7 have ?

Mathematics

Alla [95]3 years ago
7 0
I find it of tremendous use to convert to the slope intercept form to easily visualize the lines.  The first is:
y = 5x - 7  [Dividing both sides by 2] and the second is:
-y = -5x + 7  [Subtracting 5x from each side]
y = 5x - 7 [Dividing each side by -1]

These two equations represent the same line.  If the lines were parallel, there would be no solution.  If the lines intersected, there would be only one unique solution satisfying both equations (the point of intersection).

In this case, where the two equations represent the same line, the number of solutions is infinite.

The answer is:  <span>∞

The research shows that the name of the ferris wheel is <u>The London Eye</u> and the diameter of the wheel is 120m.

<h3>What is a research?</h3>

A research is simply carried out to get information about a particular topic or issue.

In this case, the research was conducted on the ferris wheel. The number of cars or compartments is 32.

The circumference of the wheel will be:

= 2πr

= 2π(120/2)

= 377m

The area of the wheel will be:

= πr²

= π(60²)

= 11310m²

The measure of a central angle in degrees will be:

= 360/32 = 11.25 degrees

The measure of a central angle in radians will be:

= 2π(11.25)/360

= 20 radians.

The arc length between two cars or compartments will be:

= 2π(60)(11.25)/360

= 11.78

The area of a sector between two cars or compartments will be:

= π(60²)(11.25)/360

= 353.43

An equation of a circle for your ferris wheel when the center of the ferris wheel is located at (0, 0) on a coordinate grid will be x² + y² = 3600.
