Make the coefficient of y the same in both equations:
To do this, multiply equation one by 2, and equation two by 5 (this will make the coefficient 10 in both).
14x + 10y = 38
-35x - 10y = -80
Eliminate the y variable by adding the equations from each other
(14x + 10y = 38)
+ (-35x - 10y = -80)
= -21x + 0y = -42
We now have -21x = -42. The y variable has been eliminated.
Solve for x
-21x = -42
Divide both sides by -21 to get x on its own.
x = 2
Substitute x into the equation to find y.
7*2+5y=19
14+5y=19
Subtract 14 from both sides.
5y=19-14
5y=5
Divide by 5 on both sides to get y on its own.
y=5/5
y=1
The answer is (2,1)
I believe it's 5,6
Hope this helped!
ANSWER
D. 135 m^2
EXPLANATION
The area of a kite is half the product of the diagonals.
The first diagonal is
9m+6m=15m
Note that the vertical diagonal is the axis of symmetry of the kite.
This diagonal bisect the kite
Therefore the second diagonal is
2(9m)=18m
The area of the kite
