Answer:

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

t² + 12² = 13²

t² + 144 = 169 ( subtract 144 from both sides )

t² = 25 ( take the square root of both sides )

t = $\sqrt{25}$ = 5 → A

Solve for x and y: 10x=5y+5 y=2x-1

azamat

Answer:

So there are infinite solutions along the line y = 2x-1

Step-by-step explanation:

10x=5y+5

y=2x-1

Substitute y into the first equation

10x = 5(2x-1) +5

10x = 10x-5+5

10x = 10x

This is always true

So there are infinite solutions along the line y = 2x-1
