Can someone me with this?
1. if 3x+4=y+5, then y+5=3x+4 exemplifies which property?
2. if x = y and y = 10, then x = 10 exemplifies which property?

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

Which equation represents a direct linear variationa. y=x2b. y=2/5xc. y=1/xd. y=x+3

Urgent? will give brainliest to the first correct answer what is the area of the figure?
