Answer:
B) 1 < x < 13
Step-by-step explanation:
use triangle inequality theorem which states that the sum of any two sides must be greater than the third side
let x = third side
6 + 7 > x; x < 13
6 + x > 7; x > 1
x + 7 > 6; x > -1
there will always be one inequality which produces a negative value which you can exclude from your answer because a length cannot be negative
Answer:
yes
Step-by-step explanation:
To determine if (- 8, - 7 ) is a solution to the equation
Substitute the values of x and y into the equation and if both sides are equal then it is a solution.
left side : 3(- 8) + 10 = - 24 + 10 = - 14
right side : 2y = 2(- 7) = - 14
Since both sides are - 14 then (- 8, - 7 ) is a solution to the equation.
