First multiply 2/3*9x=6x
then multiply 2/3*-6=-4
this being 6x-4.
then multiply 4*x=4x
then multiply 4*2=8
this being 4x+8.
so we have 6x-4=4x+8+2
we add the 8+2=10
6x-4=4x+10
now we subtract the x to both sides (choose 4x)
2x-4=10
now we add 4 to both sides.
2x=14
we divide 2 to both sides.
we get x=7
final answer:x=7
<span>If the walkers start at nine and want to join the cyclists at
noon, they will have been walking for 3 hours. At 5 km/h, they would have
walked for 15 km. The cyclists can travel 15 km at 12 km/h in 1.25 hours.
Therefore, the cyclists can start their journey at 10:45 am.</span>
Hello :
<span>h(x) = 6x² − 60x + 147= (x² -2(30)x+30²)-30²+147
</span>h(x) = (x-30)²-753 .....(vertex form)
<span>the axis of symmetry is the line of equation : x=30</span>
