Answer:
It should be "there ARE 254 counties in texas..."
Step-by-step explanation:
Dat is 4th degree because x is raised to the 4th power and that is the highest power of the placholder
4th degree
7v-v=12 subtract v from 7v to get 6v
6v=12 divide 12 by 6 to find variable
v=2
Answer:
<u>The only x-intercept is x = 1</u>
Step-by-step explanation:
The equation is:

We can substitute y for r(x), to write in the notation:

To get y-intercept, we put x = 0
and
To get x-intercept, we put y =0
We want to find x-intercepts here, so we substitute 0 into y and solve for x. Shown below:

<u>The only x-intercept is x = 1</u>
