Zolol [24]

Answer:

$\approx \frac{73}{12}\left(1 - \frac{1} {2\cdot73^2}\right)$

Step-by-step explanation:

$= \sqrt{\frac{73^2-1) 1}{12^2}} \\$

$= \sqrt{\frac{73^2}{12^2}\cdot\frac{73^2-1}{73^2}} \\$

$= \sqrt{\frac{73^2}{12^2}}\sqrt{\frac{73^2-1}{73^2}}\\$

= $\frac{73}{12}\sqrt{1 - \frac{1}{73^2}} \\$

$\approx \frac{73}{12}\left(1 - \frac{1} {2\cdot73^2}\right)$

Answer:

The rule for a line whose gradient is -4 and y-intercept = 8 is

$y=-4x+8$

Step-by-step explanation:

Equation of line slope intercept form is

$y=mx+b$ ------------- (1)

Where m is slope or gradient and b is y-intercept

Here

$m=-4 \ \ \ and \ \ \ b=8$

Substituting values in equation (1)

$y=-4x+8$
