Solve this system of linear equations. separate the x- and y- values with a comma. -13x=97-19y -17x=83+19y

The solution is (-6, 1).

Step-by-step explanation:

Rewrite this system as

-13x=97-19y

-17x=83+19y

Now combine these two equations.  19y and -19y will cancel each other:

-30x = 180, so x = -6.

Now substitutte -6 for x in the first equation:

-13(-6) = 97 - 19y, or 78 = 97 - 19y.  This simplifies to:

-19 = -19y, so y = 1.

The solution is (-6, 1).

answer: b.36 feet

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
