Can i please have help thanks.

Answer:

$q = 2(3r + 8)$

Step-by-step explanation:

There are two variables, q and r in the expression given. To make r the independent variable, it simply means, make q the subject of the formula, so that variable q would be dependent on variable r. As r changes, q changes also.

Thus,

$q - 10 = 6(r + 1)$

Open the parenthesis

$q - 10 = 6r + 6$

Add 10 to both sides

$q - 10 + 10 = 6r + 6 + 10$

$q = 6r + 16$

$q = 2(3r + 8)$

Answer:

$-1/x^2$

Step-by-step explanation:

First, let's simplify the expression on the right:

$1/\sqrt{x^2}=1/x$

Next, rewriting 1/x as x⁻¹, we can use the power rule to differentiate both sides with respect to x:

$y=x^{-1}\\dy/dx=d/dx(x^{-1})\\dy/dx=-x^{-2}=-1/x^2$
