CAN SOMEONE PLEASE HELP ME WITH MY MATH ASAP PLEASE

x = 15

Step-by-step explanation:

Consider the right triangle on the left with hypotenuse h₁  , then

Using Pythagoras' identity

h₁² = x² + 9²

Consider the right triangle on the right with hypotenuse h₂ , then

h₂² = x² + 25²

Now consider the large right triangle with legs h₁ and h₂ , then

h₁² + h₂² = (9 + 25)² , substitute values

x² + 9² + x² + 25² = 34² , that is

2x² + 81 + 625 = 1156

2x² + 706 = 1156 ( subtract 706 from both sides )

2x² = 450 ( divide both sides by 2 )

x² = 225 ( take the square root of both sides )

x = = 15

1.true 2.false? ? i think. .

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
