I searched and did find radio wave discussions but nothing like this question.
I have a wireless transmitter and receiver about 40 yards apart.
Can a weak battery (9 volt) in the transmitter cause the signal to be delayed getting to the receiver and result in a slow response?
Or will it just not be strong enough to get the signal to the receiver and result in no response?

I would say it depends on the system.
You could build a digital transmission system that selects what enoding is used and the resulting bitrate by the amount of available power so a message takes longer to transmit. The data rate does depend on signal-to-noise ratio and if you can’t transmit at the same power the data rate needs to drop.
It could alos be that the system transmits data the same way all the time and the output power get reduced if the battery is weaker. Then it might not work at all at that range.
Another option is lower power result in more transmission error and you need to retransmitt the same thing many times to get the message through.
How a system is designed depend on the independent usage, how it works depend on the design.
A weak battery can’t slow down a signal. All it could do is make it weak enough not to be received or not have enough power to transmit anything.
