Answer:
BA = 12
Step-by-step explanation:
All the right triangles are similar, so the ratio of hypotenuse to long side is a constant. In particular ΔABC ~ ΔDBA, so ...
hypotenuse/long-side = BC/BA = BA/BD
Cross multiplying gives ...
BA² = BC·BD
BA = √(BC·BD) = √(16·9)
BA = 12
First you need to substitute the xs and ys into point slope ( y1 - y2 = m(x1 - x2). in this example it would be 3-6= m(0 - (-1)). then you just simplify, so -3 = m(1) -3=m. the slop is -3. because you already know the y-intercept is 3 (0,3), you can substitute everything into slope intercept (y=mx+b). so the answer is y=-3x+3.
I hope this helped, let me know if you are still confused and i can help :)

Answer:
-3
Step-by-step explanation:
Let x equal the mystery number
Our equation will be:
x - 5 = 1 + 3x
Subtract x from both sides
-5 = 1 + 2x
Subtract 1 from both sides
-6 = 2x
Divide both sides by 2
-3 = x
