9900 because you divide 99000 by 10
30X15=450. 450:100= 4,50. 30+4,50= 34,50
Y=2x+2 easy
The slop=2/1
Y-int= (0,2)
6.4x10^5 + 0.36x10^5 = 6.76x10^5, or 676,000
<span>x^2+15=8x
</span><span>x^2-8x=-15
x^2 - 2 (x)(4) =-15
adding 16 on both sides
</span>x^2 - 2 (x)(4) +16=-15+16
x^2 - 2 (x)(4) + 4^2= 1
(x-4)^2=1
taking square root on bothsides x-4 = +-1
so x-4=1 or x-4=-1
x-5 or x=3
