Answer:

20.8

Step-by-step explanation:

Use the Pythagoras's Theorem

12²-36²= $\frac{x}{2}$ ²

144-36= $\frac{x}{2}$ ²

108= $\frac{x}{2}$ ²

Root both sides

√108=√ $\frac{x}{2}$ ²

$\frac{x}{2}$ ≈10.4

$\frac{x}{2}$ ·2=10.4·2

x=20.8

siniylev [52]

Answer:

y = -2x

Step-by-step explanation:

It passes through -5, 10 and 5, -10

gradient = Δy/Δx

gradient = -10 - 10 / 5 -- 5

gradient = -20 / 10

gradient = -2

let's use -5, 10 for y = mx + b

10 = -2(-5) + b

10 = 10 + b

b = 10 - 10

b = 0.

the equation of the line is just y = -2x
