Answer:
1 and -7
Step-by-step explanation:
Answer:
40.5 m²
Step-by-step explanation:
Area of the shaded = area of the square - area of the triangle
Area of square = s²
s = 9 m
Area of square = 9² = 81 m²
Area of triangle = ½*b*h
b = 9 m
h = 9 m
Area of triangle = ½*9*9 = 40.5 m²
Area of the shaded = 81 - 40.5 = 40.5 m²


We could solve for 'x' in the 2nd equation and then plug that into the first equation for 'x' and solve for 'y':

Subtract 6y to both sides:

Divide -2 to both sides:

Plug in 3y + 17 for 'x' in the first equation:


Distribute 5:

Combine like terms:

Subtract 85 to both sides:

Divide 17 to both sides:

This is the y-coordinate of the solution.
