Find the limit. use l'hospital's rule if appropriate. if there is a more elementary method, consider using it. lim x→4 x2 − 16 x

ivolga24 [154]

Probably you are supposed to compute

$\displaystyle\lim_{x\to4}\frac{x^2-16}{x^2-4x}$

Factorize the numerator and denominator, then simplify:

$\displaystyle\lim_{x\to4}\frac{(x-4)(x+4)}{x(x-4)}=\lim_{x\to4}\frac{x+4}x=\frac{4+4}4=2$

Y=-3x+2<br> y=4x-5<br> FInd the y slope. FInd the x slope.

mars1129 [50]

Both these expression are written in slope-intercept form. y = mx + b

m = slope

b = y-intercept

We can find the slope of each expression by finding what m is in each equation.

y = -3x + 2 -> m = -3

y = 4x - 5 -> m = 4

Remember that m = slope
