The answer is y=(1/2)x -5
You are given the slope and a core donate pair so you plug them in to the equation. 2=x. -4=y. And (1/2)= m
Then work out like a one step equation
Question a is 48 i think! because if you do 12 x how many side there are. it’s 4 so 12 x 4
If Josie bought a mirror with 5 sides it would be a pentagon
The altitude to the hypotenuse of a right triangle is the mean proportional between the segments into which it divides the hypotenuse ⇒<span>
</span>altitude = √(9*3) = √27
<span>By the Pythagorean theorem:
y = </span>√(9² + (√27)²) = √(81+27) = √108 = 6√3 ← answer
