"horizonally" and "x-coordinate" are very much related.
If you start with a point and move the point horiz., the x-coordinate will change accordingly. If the original point were (2,3) and the point is translated 3 units to the right, then the new x-coord. would be 2+3, or 5: (5,3).
Answer:
y = x² + 3x
Step-by-step explanation:
y = (x * x) + (3 * x)
y = x² + 3
I think 0 because 9+11+12=32
32+-32 or 32-32= 0
Answer:
x is less than or equal to -6 or x is greater than or equal to 1
Answer:
Finally, substitute AB = 6 and BC = 18 - 2AC in
AB + AC > BC 3rd Triangle Inequality condition
6 + AC > 18 - 2AC
-12 > -3AC
4 < AC
AC > 4
So putting all three results together
AC < 12, AC < 8, and AC > 4
Since AC is less than 8, it's automatically less than 12,
so we can dispense with AC < 12. So we have:
AC < 8 and AC > 4 which can be combined and written as
4 < AC < 8 [that is, AC is between 4 and 8]
