***50+ points if you help!*** Please help, it's stuff about angles and triangles, anything would help. I will be giving out "Brainliest."

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257

You can find the constant of proportionality by finding the ratio of

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1
