Answer:

a

Explanation:

y=-2/3x+7  you multiply everything by 3 to cancel the fraction

3y=-2x+21  add 2x to both sides cuz u want the x and y on the left side for standard form

2x+3y=21

Answer:

2x + 3y = 21

Explanation:

We have to work backwards here, in order to find out what the standard form of this equation would be.

So it's safe to say, since the slope has 3 as the denominator, we would've divided by 3 at some point when turning the standard form to slope-intercept form.

Dividing is usually the last step, and we do this to isolate the y. So this means that 3 was in front of y instead of x. This also means that the y-intercept was able to be divided by 3. (We can rule out the second and last options, for these reasons.)

Now the problem is looking like this:

3y = -2x + 21

Next we would've had to move the 2x in order for it to be on this side, so now we have to move it back. So we will add 2x on both sides to get 2x + 3y = 21.

Here's your answer. Sorry the explanation is a little lengthy btw.

Hope this helps you though :)

Neurotransmitters categorized as inhibitory are expected to _______. A. act independently of their receptor proteins B. close po
Ksenya-84 [330]

The correct option is D.

Neurotransmitters categorized as inhibitory are expected to hyperpolarize the membrane.

At inhibitory synapses, release of neurotransmitters causes inhibitory postsynaptic potentials or IPSP, which is a hyperpolarization of the presynaptic membrane.

Actually, depolarization and hyperpolarization occurs on neuron when an ion channel in the membrane open or close which can alter the ability of certain types of ions which enter from or exit out of the cell.

Neurotransmitters which is inhibitory have inhibitory effects on the neuron as it means they can decrease the possibility that the neuron will tend to fire an action. Modulatory neurotransmitters can also affect various neurons at the same time which results in the influencing effects of other chemical messengers.

Inhibitory neurotransmitter somehow decreases the action potential of the neuron. When the action potential falls below a certain level which is called threshold potential, the neuron will not be able to generate action potentials and thereby unable to exit the nearest neurons.

So, neurotransmitters are in general expected to hyperpolarize the membrane in some extent.
