The solution to this system of linear equations y - x = 6 and y + x = -10 is (-8, -2).

y - x = 6

⇒y = x + 6

y + x = -10

⇒y = - x - 10

Since both equations are equal to y, equate them.

x + 6 = - x - 10

x + x = - 10 - 6

2x = - 16

Divide both sides by 2

x = -8

Put the value of x in either of the equations

y - x = 6

y - (-8) = 6

y + 8 = 6

y = 6 - 8

y = - 2

Therefore, the solution to the system of linear equations is (-8, -2).

The exact volume of the solid is 963 2/3π cubic cm

From the question, we have the following parameters that can be used in our computation:

Shapes = Half-sphere and cylinder

A half-sphere is called a hemisphere, and the volume is calculated as

V₁ = (2/3)πr³

From the given figure (see attachment), we have

r = 14 cm/2

r = 7 cm

Substitute the known values in the above equation, so, we have the following representation

V₁ = (2/3)π * 7³

V₁ = 686/3π

Next, we have the volume of the cylinder to be

V₂ = πr²h

Where

r = 14 cm/2

r = 7 cm

And

h = 22 - 14/2 = 15

So, we have

V₂ = πr²h

Substitute the known values in the above equation, so, we have the following representation

V₂ = π * 7² * 15

V₂ = 735π

The volume of the solid is then calculated as

V = V₁ + V₂

So, we have

V = 686/3π + 735π

Evaluate the sum

V =  963 2/3π

Hence, the volume is 963 2/3π cubic cm

The length of the other leg of the right triangle is √70. The result is obtained by using the concept of the Pythagoras theorem.

The Pythagoras theorem states that the square of the hypotenuse of a right triangle is equal to the squares of the other length sides. It can be expressed as

a² + b² = c²

Where

Base altitude is also called as legs of the right triangle.

A right triangle has a leg length of √11 and hypotenuse of 9. Find the length of the other leg!

Let's say

The length of other leg is b, the shorter side of hypotenuse.

By using the Pythagoras theorem, we get b.

a² + b² = c²

(√11)² + b² = 9²

11 + b² = 81

b² = 81 - 11

b² = 70

b = √70

Hence, the length of the other leg of the right triangle is √70.

To find the coordinates of a triangle with midpoints, you must first calculate the midpoints of each side by averaging the coordinates of the two endpoints.

To find the coordinates of a triangle with midpoints, you first need to calculate the midpoints of each side of the triangle. To do this, take the two endpoints of the side and average their coordinates. For example, if the two endpoints are (x1, y1) and (x2, y2), then the midpoint would be ((x1+x2)/2, (y1+y2)/2). Once you have all the midpoints, you can use the midpoint formula to calculate the coordinates of the triangle. The midpoint formula states that the coordinates of the triangle can be found by taking the average of the midpoints of the three sides.

The equations used to determine the number of bracelets and necklaces made are x + y = 13 and 8x + 24y = 168, respectively.

A variable in Algebra is an alphabet used to represent an unknown number. It denotes the value. A variable is a quantity that can be altered in response to a mathematical problem. Many algebraic expressions and equations use the generic letters x, y, and z. A variable is, in other words, a symbol for a number whose value is unknown.

Given:

Each bracelet contains 8 grammes of gold, and each necklace contains 24 grammes of gold. Using 168 grammes of gold, the jeweller created 13 bracelets and necklaces.

According to the question,

Let x denote the number of bracelets and y the number of necklaces made by the jeweller.

The jeweller made a total of 13 bracelets, This means that

⇒ x + y = 13

It is assumed that each bracelet contains 8 grammes of gold and each necklace contains 24 grammes of gold. Using 168 grammes of gold, the jeweller created 13 bracelets and necklaces. That is to say,

⇒ 8x + 24y = 168

An exponential function can be equal to 1, but it would have to be a special case.

To determine this:

An exponential function has the form f(x) = ab^x, where a and b are constants. For the function to be equal to 1, the output value of the function must be 1 for all values of x. Therefore, we must have:

[tex]ab^x = 1[/tex]

In order for this equation to be true for all values of x, a and b must be chosen such that:

ab = 1

This means that a and b must be reciprocals of each other. For example, if a = 2, then b = 1/2. In this case, the function [tex]f(x) = 2(1/2)^x[/tex] would be equal to 1 for all values of x.

Another example would be if a = 1 and b = 1. In this case, the function [tex]f(x) = 1(1)^x[/tex] would be equal to 1 for all values of x.

It's important to note that while an exponential function can be equal to 1, it would only be in cases where a and b are reciprocals of each other and not with any other values.

What is a rectangle, exactly?

A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. As a result, it is sometimes referred to as an equiangular quadrilateral.

                 The term "parallelogram" can also be used to describe a rectangle because the opposing sides are equal and parallel.

The height of the first rectangle is 2 and the area is 6x^{2}. To get to 6x^{2} you have to multiply by 3x^2.
