Answer:
y = 18
Step-by-step explanation:
[tex] \frac{21 + 7}{21} = \frac{y + 6}{y} [/tex]
[tex] \frac{28}{21} = \frac{y + 6}{y} [/tex]
Cross multiply
28*y = 21(y + 6)
28y = 21y + 126
28y - 21y = 126
7y = 126
y = 126/7
y = 18

A category of non-Euclidean geometry, spherical geometry is a subset of elliptical geometry. Any type of geometry that is not founded on conventional planes is known as non-Euclidean geometry. Lines in non-Euclidean geometry are not always the usual straight lines found in Euclidean geometry (i.e., plane geometry).
We require opposing sides and angles in order to use the sine rule. We can utilise this knowledge to locate the side that is opposite the other angle if we know two angles and one of the sides opposite. Accuracy points may be lost because of this.

What is System of Linear Equation ?An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, whereas B is a constant. A linear equation with two variables has the standard form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present.
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
A linear equation is an algebraic equation in which each term has an exponent of 1, and which, when plotted on a graph, always yields a straight line. It is called a "linear equation" for this reason.
The equation is
2 - x +x/2 + x = 0
⇒ x/2 = -2

which equation represents the line that psses through (2,3) and (-2,5)
Answers
The equation of line that passes through (2,3) and (-2,5) is y = (-1/2)x + 4.
What is the equation of line that passes through the given points?The point-slope form is expressed as;
( y - y₁ ) = m( x - x₁ )
Where m is slope, x₁ and y₁ are the coordinates of the point .
Given the data in the question;
Point 1 (2,3)
x₁ = 2y₁ = 3Point 2 (-2,5)
x₂ = -2y₂ = 5First, determine the slope.
Slope m = (y₂ - y₁)/(x₂ - x₁)
Slope m = ( 5 - 3 ) / ( -2 - 2)
Slope m = 2 / -4
Slope m = -1/2
Plug the slope m = -1/2 and point (2,3) into point-slope formula and simplify.
( y - y₁ ) = m( x - x₁ )
( y - 3 ) = (-1/2)( x - 2 )
y - 3 = (-1/2)x - (-1/2)2
y - 3 = (-1/2)x + 1
y = (-1/2)x + 1 + 3
y = (-1/2)x + 4
Therefore, the equation of the line is y = (-1/2)x + 4.

C) 144 1/4
D) 156 1/4
I have the right answer, show work please
Answers
Answer:
156 1/4
Step-by-step explanation:
Assume the room is a square.
side = 12 1/2 ft
area = (side)²
area = (12 1/2 ft)²
area = (12 1/2 ft) × (12 1/2 ft)
area = (144 + 6 + 6 + 1/4) ft²
area = 156 1/4 ft²

When an equation simplifies to 0=0 then it has true for all real numbers or else it does not have solution.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
3x +6 = 2x +10 +x -4
Subtract (3x+6) from both sides:
(3x +6) -(3x +6) = (2x +10 +x -4) -(3x +6)
0 = x(2 +1 -3) +(10 -4 -6)
0 = 0
0 = 0 . . . . has "all real numbers" as a solution set
6x +2 -2x = 4x +1
Subtract (4x+1) from both sides:
(6x +2 -2x) -(4x +1) = (4x +1) -(4x +1)
x(6 -2 -4) +(2 -1) = 0
0x +1 = 0
1 = 0

Which of the following tables may represent a linear function?
Answers
The table that represents a linear equation is the first one, and the line can be:
y = -4x - 1
Which of the following tables can represent a linear function?A general linear function can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
Now, notice that if we evaluate the line in x + 1, we will get:
y = a*(x + 1) + b
y = a*x + a + b
So, for an increase of one unit on the variable x, we have a constant increase in the y value.
Now, if you look at the first table, you can see that for each increase of 1 unit on the value of x, the value of y decreases by 4.
So that is the table that can represent a linear function.
And the line is:
y = -4x - 1
