Answer:
Mx+b=y
-1/2x -2=y is your answer or y= -1/2x -2(<-- just the flipped version)

Answer: B. (5,3)</h3>
How to get this answer:
x+y = 8 solves to y = -x+8 after isolating y. You subtract x from both sides.
Plug this into the second equation and solve for x
3x + 2y = 21
3x + 2( y ) = 21
3x + 2( -x+8 ) = 21 ... replace y with -x+8
3x - 2x + 16 = 21
x + 16 = 21
x = 21-16
x = 5
Use this to find y
y = -x+8
y = -5+8
y = 3
We have x = 5 and y = 3 pair up to get the ordered pair solution (5,3)
Answer:
5,720,000 Sq Feet.
Step-by-step explanation:
They are asking the Area of a Trapezoid
Equation =( base + base / 2) x height
Lets first set it up. We know that A-B is 200 feet. & D-C is 260. They are both the bases.
So if you multiply them (200 x 260) You will get 52000.
Now we divide that by 2. (52000 / 2 = 26000)
Now it says the straight line is 220. I think this refers to the height.
Now we multiply 26000 x 220. Which is 5720000.
Its a pretty big number, but that is the answer! :)
Hope this helps!
