Answer:
Option B
y coordinate is 0
Step-by-step explanation:
We have in two dimension rectangular system of coordinates with two mutually perpendicular lines called x and y axis.
X axis is the horizontal line and y the vertical line, the point of intersection of these two lines is called origin with x=0: y=0
To the right of origin, positive values are marked and left negative. Similarly for y axis, above origin positive values and below negative values.
Thus we have along x axis, y values to be 0
Hence any point on x coordinate will be of the form (a,0) where a can be any real number
So option B is right
Answer:3333

Answer:
Step-by-step explanation:
The function is 
where x is the number of bottles of soda.
The domain means the set of "allowed" x values.
Also, f(x) means the amount of money left, which cannot be less than 0. So we put 0 into f(x) and solve for x:
This means the highest number of bottles you can buy is 10. So the domain is anything from 0 to 10. <em>You can buy 0 until highest 10 bottles. Hence the domain is </em>
So when dividing scientififc notations you must divide 2.8 and 1.4 which gives you 2. Now you need to subtract the exponents 7-3 and that gives you 4. Now put it togethor to get 2x10^4.
2.8/1.4=2
7-3=4
I hope this helped you!
Answer:
A. 215x + 780 = 2500
Step-by-step explanation:
Multiply both sides of the equation by 100 to eliminate the decimal fractions.
(2.15×100)x + 7.8×100 = 25×100
215x + 780 = 2500
