A common formula to convert a Fahrenheit temperature (F) to a Celsius temperature (C) is C = 5/9(F - 32)

a. Solve the temperature for F in terms of C. Show your work.

b. Suppose you use the formula C = 5/9
(F - 32) to convert a Fahrenheit temperature to a Celsius temperature. Explain how you can verify that your Celsius result is correct.

c. Find the temperature whose numerical value is the same on the Fahrenheit and Celsius scales. Show the steps in your work.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

good luck on ur quiz test or homework. have a good day : )

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
