City R has a temperature of −2 °F. City S has a temperature of −6 °F. Use the number line shown to answer the questions:

[ Number line from negative 8 to positive 8 in increments of 1 is shown. ]

Part A: Write an inequality to compare the temperatures of the two cities.

Part B: Explain what the inequality means in relation to the positions of these numbers on the number line.

Part C: Use the number line to explain which city is warmer.

good luck!

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

i believe it's a.

i'm not sure on this one, most likely correct.

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
