Working out the lenght of the blue-dashed line:
SOH
47 is the Hypotenuse.
the blue line is the adjacent.
adjacent= Cos(30) x47
adjacent= 40.7
Working out x :
40.7 is the opposite this time.
x is the adjacent.
x = 40.7/ Tan(44)
x = 42.1

Answer:
(x -4)^2 = 13
Step-by-step explanation:
To solve this equation using the completing the square method;
x^2 - 8x + 3 = 0
The first step is to take +3 to the right-hand side of the equation, 3 becomes negative when it crosses over the equality sign.
The equation becomes;
x^2 - 8x = -3
The next step is to add square of half of the coefficient of x to both-side of the equation. That is; you will add (-4)^2 to both-side of the equation.
x^2 - 8x + (-4)^2= -3 + (-4)^2
Then, we factorize the left hand side of the equation and our equation
(x - 4)^2 = -3 + (-4)^2
The we simplify the right-hand side of the equation
(x - 4)^2 = -3 + 16
(x - 4)^2 = 13
Answer B
x²-8x+3=0
==>x²-2*4*x+16-13=0

i.e.
B. Original is a function; inverse is a function
Answer:
The correct option is B.
Step-by-step explanation:
The formula for converting from Celsius to Fahrenheit temperatures is
A relation is called a function if there exist a unique output for each input.
The original formula is a function because for each value of C, there exist a unique value of F.
The inverse of the function is
The inverse is also a function because for each value of F, there exist a unique value of C.
Therefore original is a function; inverse is a function. Option B is correct.

move y by itself
7x+5y=20
minus 7x from both sides
7x-7x+5y=20-7x
0+5y=20-7x
5y=20-7x
divide both sides by 5
5y/5=(20-7x)/5
y=(20-7x)/5
y=(20/5)+(-7x/5)
