Which graph represents 2x-5y< 15

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

Select the correct answer from each drop-down menu. rewrite the formula to find voltage. the formula for electrical power (p, in watts) is where v is the voltage in volts and r is the resistance in ohms. for a particular brand of water heater, r is 32 ohms and p is 0.5 watts. the formula to find v is , and the voltage at which the heater operates is volts.
