If \mathbf{10x-2y=-3}10x−2y=−3 and \mathbf{9x+7y=8}9x+7y=8 are true equations, what would be the value of \mathbf{x-9y}x−9y?

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.
