Use the relationship between c and f given above to find the interval on the fahrenheit scale corresponding to the temperature range 20 ≤ c ≤ 25. (enter your answer using interval notation.)

Step-by-step explanation:

F=9/5*20+32=36+32=68

again for 25 C

F=9/5*25+32=45+32=77

\[

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
