F(n) = f(1) + d(n - 1), find f(9) for (1, 55)(2, 45) (3, 35)(4, 25)

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

Through non-collinear points there is exactly one plane.

A(1,1) b(-3,0) c(-4,-1) d(3,-2) drag it to correct position
