The label on the car's antifreeze container claims to protect the car between −30°c and 130°c. to convert celsius temperature to fahrenheit temperature, the formula is:
c = 5/9(f − 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car.

a.) -30> 5/9(f-32)> 130; -22> f> 266

b.) -30< 5/9(f-32)< 130; -22
c.) -30< 5/9(f-32); -22
d.) 5/9(f-32)< 130; f< 266

Lems1. the following data set represents the scores on intelligence quotient(iq) examinations of 40 sixth-grade students at a particular school: 114, 122, 103, 118, 99, 105, 134, 125, 117, 106, 109, 104, 111, 127,133, 111, 117, 103, 120, 98, 100, 130, 141, 119, 128, 106, 109, 115,113, 121, 100, 130, 125, 117, 119, 113, 104, 108, 110, 102(a) present this data set in a frequency histogram.(b) which class interval contains the greatest number of data values? (c) is there a roughly equal number of data in each class interval? (d) does the histogram appear to be approximately symmetric? if so, about which interval is it approximately symmetric?

Does anyone know how to do geometryme with this problem

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
