The y-coordinates are the same, so the length of this horizontal line segment is the difference between the x-coordinates.
Length = 7 - (-5) = 12 units
Answer:
All Real Numbers
Step-by-step explanation:
<span><span>3+<span>xx</span></span>=19 </span>
<span /><span><span><span>x2</span>+3</span>=19 </span>
<span /><span>x2+3−3=<span>19 </span></span>
<span><span>−3</span></span><span><span><span><span><span>x2</span>=16</span></span></span></span>
<span><span><span><span /><span>x=<span>±<span>√16</span></span></span></span></span></span>
<span><span><span><span><span><span /></span></span></span></span></span>x = <span><span><span><span>4</span> or </span></span>x </span>= <span>−<span>4</span></span>
Synthetic division yields
..... || 2 2 -12 1 6
-3 || -6 12 0 -3
= = = = = = = = = = = = = =
..... || 2 -4 0 1 3
which translates to
i believe the answer is concave
