Hello : 
let : A(2, 1) , B(6, 4) , C<span>(–4, 9)
calculate : AB  , AC,  BC 
AB = </span>√((6-2)² + (4-1)²) = <span>√25 = 5
AC= </span>√((-4-2)² + (9-1)²) = √100 = 10
BC= √((-4-6)² + (9-4)²) = √125 
<span>by  pythagorean theorem : BC² = AC² + AB² 
</span><span>the triangle is rectangle in : A</span>

The temperature in degrees Celsius, c, can be converted to degrees Fahrenheit, f, using the equation f-c+32. Which
Basile [38]

It is a function because every Celsius temperature is associated with only one Fahrenheit temperature. Therefore, option B is true.

<h3>How to convert Celsius into Fahrenheit ?</h3>

We are given that the temperature in degrees Celsius C can be converted to degrees Fahrenheit F

We know that the formula

\dfrac{C}{5} = \dfrac{F - 32}{9}

If we are substituting c = -40

Then, we get

\dfrac{C}{5} = \dfrac{F - 32}{9}\\\\\dfrac{-40}{5} = \dfrac{F - 32}{9}\\\\-8 \times 9 = F - 32\\\\F = -72 + 32\\\\F = -40

For every Celsius temperature, we get only one value of Fahrenheit.

The function is one-one because for every value of Celsius we get a unique value of Fahrenheit.

Hence, it is a function because every Celsius temperature is associated with only one Fahrenheit temperature.

Therefore, option B is true.

Which letter represents the first number in an ordered pair?
Step2247 [10]

Also, in the world of variables, and the alphabet, x is before y.

So x represents the first number in an ordered pair.

hope it helps!
