Answer:
Therefore, the side lengths 10, 14, and 15 form a triangle.
Step-by-step explanation:
The Triangle Inequality Theorem defines that if we are given the three sides of a triangle, then the sum of any 2 sides of a triangle must be greater than the measure of the third side of the triangle.
The three conditions that need to be met for any triangle with the side lengths A, B, and C.



Given the side lengths of a triangle
Let us check whether it satisfies the three conditions.
10+15 > 14 → TRUE
10+14 > 15 → TRUE
14+15 > 10 → TRUE
As all the conditions are met. Therefore, the side lengths 10, 14, and 15 form a triangle.
Answer:
x=1, y= 7
Step-by-step explanation:
−5x+2y=9
y=7x
Substitute the second equation in for the first
-5x +2(7x) = 9
-5x + 14x = 9
Combine like terms
9x = 9
Divide by 9
9x/9 = 9/9
x =1
Now find y
y = 7(1)
y =7
I can’t see your scream is crack
Identify and sum up the x^2 terms: Result: 3x^2
Next, ident. and sum up the x terms: Result: (1/3 + 2) = (7/3)x
Last, ident. and sum up the const. terms: Result: -2 - 6 = -8
The sum of these two functions is 3x^2 + (7/3)x - 8.
There would be four 90 degree angles in the intersection of two lines.
