Find the hypotenuse of each isosceles right triangle when the legs are of the given measure
miskamm [114]
A isosceles triangle has two sides which are the same. So, we know two of the sides of the triangle are 6 square root 2.  (6 square root 2)^2 + ( 6 square root 2) ^2 = (h)^2   ->  72 + 72 = (h)^2 -> 144 = h^2 - >  h = 12

Hope this helps! I had to write out square root because I don't have the symbol.

Solve the system using substitution. -x+y=9 and x-y=-9
Elina [12.6K]

Answer:

Infinite Number of Solutions

Step-by-step explanation:

Hello!

We can solve for y in the first equation, and plug that value in for y in the second equation.

<h3>Find the Equation for Y</h3>
  • -x + y = 9
  • y = 9 + x

Now that we know the equation for y, we can plug that in for y into the second equation to solve for x.

<h3>Solve for X</h3>
  • x - y = -9
  • x - (9 + x) = -9
  • x - 9 - x = -9
  • -9 = -9

Since the equations match, there are an infinite number of solutions.

If we take a close look at the equations, we can also see that they are the same equation, but with flipped signs.
