What is the equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
From the given table choose;
⇒ (x₁ , y₁ ) = (3, 5) & (x₂, y₂ ) = (3, 5)
Since, We know that equation of line is,
⇒ y – y₁ = ((y₂ – y₁)/(x₂ – x₁ )) (x – x₁)
⇒ (y - 3) = ((10-5)/(6-3))(x - 3)
⇒ 3(y - 3) = 5(x - 3)
⇒ 3y = 5x -15+9
⇒ 5x- 3y = 6 ….(i)
This is the required equation.
Given that; the length of wall on blue print = 10 inch
Then, put x = 10 in equation (i) we get;
⇒ 5x10 – 3y = 6
⇒ -3y = 6 - 50
⇒ y = 14.6 ft
The actual length be = 14.6 ft
And, Also given that actual width of window = 2.5 feet
Then put y = 2.5 in equation (i) we get
⇒ 5x – 7.5 = 6
⇒ 5x = 13.5
⇒ x = 2.7 inch
Thus, The width of the window in the blueprint is 2.7 inch.

What is the distance between the points R(5, 7) and S(-2, 3)?
Answer:
Step-by-step explanation:
D
The distance between points is √65.
What is distance?The length of the line that connects two points is the distance between them. The distance can be determined by subtracting the coordinates that are not the same if the two points are on the same horizontal or vertical line.
The distance formula is used in analytic geometry to determine the distance between two lines, the sum of the lengths of all sides of a polygon, the perimeter of polygons on a coordinate plane, the area of polygons, and a variety of other measurements.
Given coordinates
R(5, 7) and S(-2, 3)
to find the distance between
the formula of distance for coordinates is
d = [tex]\sqrt{(y_{2} - y_{1} )^{2} + (x_{2} - x_{1} )^{2} }[/tex]
here y₂ = 3, y₁ = 7
x₂ = -2, x₁ = 5
substitute value in equation we get
d = [tex]\sqrt{({3 - 7 )^{2} + (-2 - 5 )^{2} }[/tex]
d = [tex]\sqrt{({-4 )^{2} + (-7 )^{2} }[/tex]
d = √(16 + 49)
d = √65
Hence the distance is √65.

x = (2 + i) and (2 - i) are the roots of the quadratic equation f(x) = x² - 4x + 5.
What are roots of a quadratic equation?The values of variables satisfying the given quadratic equation are called its roots.
Given (2 + i) and (2 - i) are roots of the quadratic equation.
Let the quadratic equation be f(x).
(x - (2 + i)) and (x - (2 -i)) are the factors of f(x).
Since, f(x) is a quadratic equation, it has only two roots.
f(x) = (x - (2 + i))(x - (2 - i))
f(x) = x² - (2 - i)x - (2 + i)x + (2 - i)(2 + i)
f(x) = x² - 2x + ix - 2x - ix + 4 - i²
f(x) = x² - 4x + 4 + 1
f(x) = x² - 4x + 5

Find ghe solution to the system. Write your solution as an ordered pair (x,y) with no spaces,no solution,or infinitely many.y=4x and 3x+2y=55
Answer:
The solution of the system is (5, 20).
Step-by-step explanation:
y = 4x and 3x + 2y = 55 are simultaneous equations. To find the unknowns, we have to solve these equations simultaneously.
The first can be rewritten as
4x – y = 0.
Therefore, we have:
4x – y = 0
3x + 2y = 55
Multiplying the first equation by 2 all through, we have
8x – 2y = 0.
So we can now combine the second equation with the first multiplied by 2.
8x – 2y = 0
3x + 2y = 55
Adding these equations we have:
11x = 55
Divide both sides by 11 and we have
x = 5
Substitute x = 5 in equation 1, we have
4(5) – y = 0
y = 20.
Therefore, x = 5 and y = 20.
The solution of the system is (5, 20).

A number plus 17 is 25 algebraic expression
Answer:
x + 17 = 25
Step-by-step explanation:
x is "a number" and you just add it to 17. (Also the answer would be 8 if you need to solve it too)
The algebraic expression is x + 17 = 25 and the number is 8 if the number plus 17 is 25.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have:
A number plus 17 is 25 algebraic expressions:
Let x be the number:
x + 17 = 25
After solving:
x = 25 - 17
x = 8
Thus, the algebraic expression is x + 17 = 25 and the number is 8 if the number plus 17 is 25.
