The temperature of a mixture in a chemistry lab was recorded every 2 minutes. The table and the scatter plot show the recorded data. Which equation represents a line of best fit for this data? ()=−2.14+53.4
()=−0.46+24.6
()=0.46+24.6
()=2.14+53.4

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

the first option is the answer.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
