Answer:
Equation of x-axis is y=0, it is a horizontal line.
Step-by-step explanation:
We need to find the equation of the x- axis and type of line it represents (vertical or horizontal ).
On the x-axis, the value of y is always 0 and the value of x can be and real number. Since y is free from x and its value is 0, therefore the equation of x-axis is
![y=0](https://tex.z-dn.net/?f=y%3D0)
Value of y remains same. So, it represents a horizontal line which intersects the y-axis at 0.
Therefore, equation of x-axis is y=0, it is a horizontal line.

16, sqrt 256
Step-by-step explanation:
consecutive integers are 1 apart
3 of them are x, x+1, x+2
x is the 1st integer, x+1 is the 2nd integer, x+2 is the 3rd integer
if the first and third integer are added (add x and x+2 together), then the result is 87 less than 5 times the 2nd integer (-87+5(x+1))
basically
(x)+(x+2)=-87+5(x+1)
expand and nice it up
2x+2=-87+5x+5
addd like terms
2x+2=-82+5x
minus 2x from both sides
2=-82+3x
add 82 to both sides
84=3x
divide both sides by 3
28=x
we can now find the 2 other integers
x+1=28+1=29
x+2=28+2=30
the 3rd integer is 30
3(x-1)2+3(y+3)=243
3(x-1)2+3y+9=243
3(x2-1)+3y+9=243
3x2-3+3y+9=243
32+3y-3+9=243
32+3y=243+3-9
3y(y+1)=237
