Answer: x = -8 ; y = -6
Step-by-step explanation:
1*x-2*y=4
1*x = 4 + 2*y
x = 4 + 2*y
Now you replace the value of x on the following equation:
-1*x+10*y=8
-1*(4 + 2*y) = 8
-4 - 2*y = 8
-2*y = 8+4
-2*y = 12
y = -12/2
y = -6
You replace the value of y in the previous equation:
x = 4 + 2*y
x = 4 + 2*(-6)
x = 4 - 12
x = -8

Answer:
1) isosceles triangle
2) 4500cm^2 or 0.45 m^2
3) 55 degrees
4) Angle SUT
5) Triangle Inequality Theorem - the sum of two side lengths of a triangle is always greater than the third side. If 8 cm is your third side, then the triangle could be constructed because 9 + 5.5 > 8.
6) SAS - Side Angle Side
