Answer:
a reflection over the x-axis
Step-by-step explanation:
say you plotted (1,1) and the plotted (-1,1). The result would be a reflection over the x-axis.
1.Simplify.
-2{x}^{2}-4x+13+12{x}^{2}+2x-25−2x2−4x+13+12x2+2x−25
2.Collect like terms.
(-2{x}^{2}+12{x}^{2})+(-4x+2x)+(13-25)(−2x2+12x2)+(−4x+2x)+(13−25)
3.Simplify.
10{x}^{2}-2x-1210x2−2x−12
Answer:
t>12
Step-by-step explanation:
t>180/15
then divide 180 by 15
and you gey t>12
