Y=x is the answer alone, since it only crosses the origin
Hey there he went 80km because there's 4blocks and 20 minutes are 1/4 of 60 so 240km devided by 3
Answer:
+1 and -1
Step-by-step explanation:
The function in this problem is:

First of all, we have to define the domain of the function, which is the set of values of x for which the function is defined.
In order to find the domain, we have to require that the denominator is different from zero, so

which means:

So the domain is all values of x, except from 4 and -7.
Now we can solve the problem and find the zeros of the function. The zeros can be found by requiring that the numerator is equal to zero, so:

This is verified if either one of the two factors is equal to zero, therefore:

and

We see that both values are part of the domain, so they are acceptable values: so the zeros of the function are +1 and -1.
The answer for this is -3.6 you need to add them together then subtract!
Answer:
You only have four terms so n can only be 1, 2, 3 or 4!
I think you mean: What is the nth term of the sequence 15, 12, 9, 6, …?
The ellipsis (…) tells us that the sequence continues.
This is an arithmetic sequence, where the general term is: a+bn
n=1:a+b=15 [Eq. 1]
n=2:a+2b=12 [Eq. 2]
Subtracting Eq. 1 from Eq.2: b=−3
Substituting this into Eq. 1: a−3=15⇒a=18
Thus the nth term is: 18−3n
