Answer: NOT POSSIBLE
Step-by-step explanation:
It is not possible for such a triangle to be formed because it violates the <em>Triangle Inequality Theorem </em>which states that the sum of two sides of a triangle must be more than the third side.
8 + 4 = 12 which is larger than the other side of 4cm so this is fine
4 + 4 = 8 is equal to the other side of 8cm so this is not fine.
So long as the summed length of any 2 of the sides is not more than the third side, a triangle cannot be formed.
Answer:
-5/7
Step-by-step explanation:
Find the change between the two x values, which is seven
Find the change between the two y values, which is -5
With slopes, the y always goes over the x, making your answer -5/7
Answer:
x = 11
Step-by-step explanation:
Substitute y = -1 into the equation.
x+2y = 9
; x+2(-1) = 9
x+(-2) = 9
x-2 = 9
x = 9+2
x = 11
