For z=2⇒ 2y+2=12
2y=12-2
2y=10
y=10:2
y=5
x - y+z=6
x - 5 + 2=6
x -3 =6
x=6+3
x=9
I= PRT
7280=26000×0.07T
7280\1820=1820T\1820
4=T
dats all
The answer was
-35 a^4 -12 a^2 + 12
Hope that helps you
Open circle on (0,-1) and arrow going strait up
if you meant y<3 then the line stops on (0,3) with an open circle
1 hour time 40 miles/ hour =1*40=40miles
0.5 *70=0.5*70=35 miles
40+35=75 miles
60 minutes+30 minutes= 90 minutes or 1 1/2hours
