So what my brother does is he places all the points on the graph and lightly go over it joining the points and then go over normally
The two angles are vertical angles so they are congruent.
3x+18=5x
2x=18
x=9
Answer:
Celss do come from pre existing cell.
Answer:

Step-by-step explanation:
The parabola's are


So



So, the points at which the parabola's intersect each other is
and 
The three points of the triangle are
,
and 
Area of a triangle is given by
![A=\dfrac{1}{2}[x_1(y_2-y_3) + x_2(y_3-y_1) + x_3(y_1-y_2)]\\\Rightarrow A=\dfrac{1}{2}[2(5-0)+(-2)(0-5)+0(5-5)]\\\Rightarrow A=10\ \text{sq. units}](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B1%7D%7B2%7D%5Bx_1%28y_2-y_3%29%20%2B%20x_2%28y_3-y_1%29%20%2B%20x_3%28y_1-y_2%29%5D%5C%5C%5CRightarrow%20A%3D%5Cdfrac%7B1%7D%7B2%7D%5B2%285-0%29%2B%28-2%29%280-5%29%2B0%285-5%29%5D%5C%5C%5CRightarrow%20A%3D10%5C%20%5Ctext%7Bsq.%20units%7D)
