3x + 6 = 12
First operation was subtraction (subtracting 6 to leave 3x alone)
Second operation was division (Dividing 3 from 3x to isolare x)

3x + 6 = 12
3x + 6 -(6) = 12 - 6
3x = 6

\frac{3x}{3} = \frac{6}{3}
3 and 3 cancels out
x = 2

A line runs tangent to a circle at the point (4, 2). The line runs through the origin. Find the slope of the tangent line.
leva [86]

Answer:

Slope of the tangent line (m) = 1 / 2

Step-by-step explanation:

Given:

Point A = (4,2)

Origin point = (0,0)

Find:

Slope of the tangent line (m)

Computation:

Slope of the tangent line (m) = (y2-y1) / (x2-x1)

Slope of the tangent line (m) = (2-0) / (4-0)

Slope of the tangent line (m) = 2 / 4

Slope of the tangent line (m) = 1 / 2
