The solution to the system of equations y is x = -5, y = 4

Elimination, substitution, and graphing are the three techniques for resolving equation systems.

Graphing the provided equations and identifying the point(s) at which they all meet is all that is required to solve a system by graphing. You can get the values of the variables you're solving for by finding this point's coordinate.

To solve the system of equations y = 1/3x + 10 - 2x and y = 4,  we can use following method:

We can begin by isolating the variable y in the first equation: y = 1/3x + 10 - 2x.

Next, we can substitute the value of y from the second equation into the first equation: 4 = 1/3x + 10 - 2x

Now we can solve for x by combining like terms and isolating x: 4 = 1/3x + 10 - 2x => 4 = -4x + 10 => x = -5

Substitute x = -5 back into either of the equations to find y:

For example, y = 1/3x + 10 - 2x => y = 1/3(-5) + 10 - 2(-5) => y = 4

So the solution is x = -5, y = 4

To find the distance between two points in a plane, you can use the distance formula. The distance formula is:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Where (x1, y1) and (x2, y2) are the coordinates of the two points, and d is the distance between the points.

For example, if you have two points (3, 4) and (7, 10), you can use the distance formula to find the distance between them:

d = √((7 - 3)^2 + (10 - 4)^2)

d = √((4)^2 + (6)^2)

d = √(16 + 36)

d = √52

d = 2√13

To find the midpoint of two points, you can use the midpoint formula. The midpoint formula is:

(x,y) = ((x1 + x2) / 2, (y1 + y2) / 2)

Where (x1, y1) and (x2, y2) are the coordinates of the two points, and (x,y) are the coordinates of the midpoint.

For example, if you have two points (3, 4) and (7, 10), you can use the midpoint formula to find their midpoint of them:

(x,y) = ((3 + 7) / 2, (4 + 10) / 2)

(x,y) = (5, 7)

The midpoint of points (3,4) and (7,10) is (5,7).

It's worth noting that both distance and midpoint formulas can be adapted for three-dimensional points, where the distance formula would be:

d = √((x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2)

and the midpoint formula would be

Similarly the circumference of the inner track (with radius r) = 2pi*r

length of each outer piece is 3.5 inch more than length of inner piece

So total outer length is 10*3.5 =35 inches more than the inner length.

In slope-intercept form, the equation of a line is represented as y = mx + b. So the equation in slope-intercept form is y = (1/2)x + 2

Slope is a measure of the steepness of a line or a linear function. It is often represented by the letter "m" and is calculated as the ratio of the change in the y-coordinates of two points divided by the change in the x-coordinates of those same two points. In other words, it is the ratio of the "rise" to the "run" of the line. The slope of a line can be positive, negative, zero, or undefined.

The slope-intercept form of a linear equation is a way to represent the equation of a line in the form of y = mx + b, where m is the slope and b is the y-intercept of the line. The y-intercept is the point where the line crosses the y-axis, and it is represented by the value of b. This form of the equation is useful because it allows us to easily identify the slope and y-intercept of a line, as well as to graph the line using these values.

The first step is to add 12y to both sides:

6x - 12y + 12y + 24 = 12y

6x + 24 = 12y

What is right triangle ?

A right triangle is a triangle in which one angle is a right angle (90 degrees). The side opposite the right angle is called the hypotenuse, and the two other sides are called the legs. The Pythagorean Theorem states that the square of the hypotenuse is equal to the sum of the squares of the legs.

The given information is that the hypotenuse, represented by c, is equal to the square root of 2. If we set c = √2 and 6 = √2, we can solve for the value of the other side of the right triangle, represented by a.

To solve for a, we can square both sides of the equation 6 = √2:

[tex]6^{2}[/tex] = [tex](\sqrt{2} )^{2}[/tex]

The zeroes of the polynomial x5-x3+2x-2 are 0.618033988749895 and -1.618033988749895.

The given polynomial is x5-x3+2x-2. To find the zeroes of the polynomial, it should be set equal to zero.

Thus, x5-x3+2x-2 = 0

To solve this equation, the quadratic formula can be used. The quadratic formula is x = [-b ± √(b2 - 4ac)]/2a.

In this equation, a = 1, b = -1 and c = -2.

Thus, x = [-(-1) ± √((-1)2 - 4(1)(-2))]/2(1)
