Solve the equation. (-7x + 2)^1/3 = (4 + 3x)^1/3

Brrunno [24]

(-7x + 2)^1/3 = (4 + 3x)^1/3
take the cube of both side to eliminate the 1/3 power
so you get
-7x+2=4+3x
combine like terms
-10x=2
solve for x
x=-1/5

Find the limit of the function algebraically. limit as x approaches negative three of quantity x squared minus nine divided by q

iris [78.8K]

The limand is continuous at $x=-3$ , so you can directly substitute $x=-3$ to get

$\displaystyle\lim_{x\to-3}\frac{x^2-9}{x^3+3}=\frac{(-3)^2-9}{(-3)^3+3}=\dfrac{9-9}{-27+3}=0$

Did you mean to write $x^3+3^3=x^3+27$ in the denominator by any chance? In that case, you would instead have

$\displaystyle\lim_{x\to-3}\frac{x^2-9}{x^3+3}=\lim_{x\to-3}\frac{(x+3)(x-3)}{(x+3)(x^2-3x+9)}=\lim_{x\to-3}\frac{x-3}{x^2-3x+9}=\frac{-3-3}{(-3)^2-3(-3)+9}=-\frac29$
