The maximum height of an Asian elephant is 9.8 feet.what mixed fraction number represents this height?

Vitek1552 [10]

9.8 / 1, but fractions don't like decimals, so 98/10
90/10 is 9, so 9 with 8/10 remaining.
8/10 can be simplified to
4/5
So it is 9 and 4/5

Two lines have equations y + m1x + c1 and y + m2x +c2, m1m2 = -1. Prove that the lines are perpendicular.

alexdok [17]

Y=mx+b
m=slope

perpendicular lines have slopes that multiply to get -1

the slopes are

for $y=m_1x+c_1$ and $y=m_2x+c_2$ , the slope are $m_1 \space\ and \space\ m_2$
since their product is -1, the lines are perpendicular
