Answer:
Step-by-step explanation:
y - 5 = 8
y = 13
The two given equations are:
<span>-14=-20y-7x and 10y+4=2x
In order to find x and y, we can do it by substitution or by elimination.
By Elimination.
</span><span>Multiply 10y+4=2x by 2
= 20y + 8 = 4x
Then add it to the second equation
</span>-20y - 7x = -14
20y - 4x = -8
---------------------
-11x = -22
x = 2
Then get y,
10y+4=2x
10y = 2x - 4
10y = 2(2) - 4
y = 0.
So the answer is x = 2, y = 0
Answer:
parabola
Step-by-step explanation:
The area is the same no matter how you calculate it.
.. A = b*h
.. 10*h = 9.8*5.6
.. h = 9.8*5.6/10
.. h = 5.488
