Which system of equations can you use to find the roots of the equation? x3 – 10x = x2 – 6

vivado [14]

$\bf \stackrel{y}{x^3-10x}=\stackrel{y}{x^2-6}\implies \begin{cases} y=x^3-10x\\ y=x^2-6 \end{cases}$

In-s [12.5K]

Answer:

y = x - 4

Step-by-step explanation:

Use point slope form: (y - y1) = m(x - x1)

m = 1

Step 1: Plug in

(y - (-3)) = 1(x - 1)

y + 3 - 3 = x - 1 - 3

y = x - 4

Answer: y = x - 4
