x+7=0 x-4=0 (x+7)(x-4)=0 how would you compare the three questions? what value(s) of x would make each equation true?

Answers

Answer 1

Answer: $x+7=0 \n \boxed{x=-7} \n \n x-4=0 \n \boxed{x=4} \n \n (x+7)(x-4)=0$
$x+7=0$ or $x-4=0$
$x=-7$ or $x=4$

S= {-7 ; 4}

Answer 2

Answer: $(x+7)(x-4)=0 \Leftrightarrow x+7=0 \vee x-4=0\n x=-7 \vee x=4$

The formula for converting from Celsius to Fahrenheit temperatures is F=9/5C+32"Determine whether the original formula is a function, and whether the inverse is a function''
A. Original is a function; inverse is not
B. Original is a function; inverse is a function
C. Original is not a function; inverse is not a function
D. Original is not a function; inverse is a function

Answers

Both the original and the inverse are functions because for each value of C there is a unique value of F and vice-versa.

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

$F=(9)/(5)C+32$

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

$F-32=(9)/(5)C$

$(5)/(9)* (F-32)=C$

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.
