While speaking on the phone to a friend in Oslo, Norway, you learned that the current temperature there was -23 Celsius (-23°C). After the phone conversation, you wanted
to convert this temperature to Fahrenheit degrees, °F, but you could not find a
reference with the correct formulas. You then remembered that the relationship
between °F and °C is linear. [UW]
a. Using this and the knowledge that 32°F = 0°C and 212°F = 100°C, find an
equation that computes Celsius temperature in terms of Fahrenheit; i. e. an
equation of the form C = “an expression involving only the variable F.”

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

first one because it can't have a fraction in it

step-by-step explanation:

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
