4x=y
2x^2 -y =0 so than we substitute the y value from the first equation inside second equation in place of y we get
2x^2 -4x =0 than we solve it for x we get
2x^2 -4x =0
2x(x-2) =0
2x =0
x_1 = 0
x - 2 =0
x_2 = 2
so for x_1 = 0 result y_1 = 4*0 = 0 so the solution set will be (0,0)
and in case of x_2 = 2 result y_2 = 4*2 = 8 so the sol. set will be (2,8)
hope this will help you

Answer:
0.6625
Step-by-step explanation:
To find the surface area, calculate the area of each shape and add it together, A pyramid has 1 square and 4 triangles in its net,
Area of square is A=s*s=0.25*0.25=0.0625.
Area of a triangle is A= 1/2 b*h = 1/2 (0.25)(1.2) = 0.15.
There are four equal triangles so together there area is 4*0.15 = 0.60.
Add the square to it and you have the surface area of the pyramid.
0.0625 + 0.60 = 0.6625
