34.5+34.9+34.2+33.4+35.9/5=34.58
So the answer is 34.58
Answer:
round to the nearest tenth
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:
The answer is B)81.33 square units
Answer:
y=-2x+5
Slope: -2
y int. 5
Step-by-step explanation:
Convert to slope intercept form
2y-10=-4x
Add 10 to both sides
2y-10+10=-4x+10
Simplify
Divide both sides by 2
![\bold{\frac{2y}{2}=-\frac{4x}{2}+\frac{10}{2}}](https://tex.z-dn.net/?f=%5Cbold%7B%5Cfrac%7B2y%7D%7B2%7D%3D-%5Cfrac%7B4x%7D%7B2%7D%2B%5Cfrac%7B10%7D%7B2%7D%7D)
Simplify
y=-2x+5
Slope: -2
y intercept: 5
