To conduct an experiment, the room temperature in a lab needs to be as close as possible to -2 degrees Celsius. Any variation from this target temperature, whether warmer or cooler, is considered an e that could affect the experiment
Function v gives the absolute temperature error as a function of the room temperature in degrees Celsius, X.
Select all statements that are true about the function and the situation.
A. When the room temperature is O degrees Celsius, v(C) has a value of 2.
B. When the room temperature is -3 degrees Celsius, the absolute temperature error, v(-3), is -1
C. When the room temperature is 3 degrees Celsius, v(3) is 5.
D The equation v(x)= x - 21 gives us the absolute temperature error when the room temperature is x degrees Celsius.
E. When v(x) = 0.5, the room temperature could be -1.5 or -2.5 degrees Celsius.
F. The equation v(x) = x + 2 gives us the absolute temperature error when the room temperature is x degrees Celsius

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

2/4 is the answer

step-by-step explanation:

x= total pieces

both ate 9 pieces

mindy ate 3 so troy ate 6

6= (1/4)x

x =24

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
