Explanation:</h2>
Remember you have to write complete questions in order to get exact and good answers. Here I can only help you in a general way since you didn't provide any function.
The x-intercept of any function occurs when we set
. Suppose you have a function expressed as follows:

In order to find the x-intercept (or x-intercepts) we set:

So we will have an equation in terms of the variable x. When solving this equation we get the x-intercept. An x-intercept located to the left of the origin implies that we will have a negative number. For instance:

Those x-intercepts are located to the left of the origin.

The answer is d hope this helps!!
Step-by-step explanation:
Divide by lomg division
The answer is D = 80
D =16t if t= 5 then d = 80
Know KHDBDCM. that's the order of prefixes. you start at Cent and move right once to Milli. So you move the decimal the same exact way in the number. So 2 centiliters is actually 20 milliliters.
