Step-by-step explanation:
Answer:
If EFGH is an isosceles trapezoid,
if
EH=4x-27+
FG=x%2B9+
EG=3y%2B19
FH=11y-21
then EH=FG and EG=FH
set up equations:
4x-27=x%2B9 .......solve for x
4x-x=27%2B9
3x=36
x=36%2F3
3y%2B19=11y-21.......solve for y
11%2B19=11y-3y
30=8y
y=30%2F8
y=15%2F4
y=3.75
so,x=12 and y=3.75
you can also check the length of equal sides and equal diagonals:
EH=4%2A12-27+=21
FG=12%2B9+=21
EG=3%283.75%29%2B19=30.25
FH=11%283.75%29-21=30.25x=12
Step-by-step explanation:
Domain is the x-values
Range is the y-values
Both listed in order from least to greatest

Answer:
A. 4,800 feet below sea level
Step-by-step explanation:
10,000 feet below sea level = -10,000 feet
"rises 5,200 feet" = +5,200 feet
=-10,000 + 5,200 = -4,800 feet
=4,800 feet below sea level.
