Write an equation for line L in point-slope form and slope-intercept form.

Natalka [10]

Line L's slope intercept form is

y = 4x + 7

It's point slope form is

y - 3 = 4 (x - -1)

You can check the point slope form and match it with the slope intercept form:

y - 3 = 4 (x - -1)

y - 3 = 4x + 4

y = 4x + 7

y = 4x + 7 = y = 4x + 7

3m - (7m+12) =2 (m-3)

viktelen [127]

Remove parentheses
3m - 7m+12 = 2 m-3

collect like terms
3m-7m-12 = 2m-6

move terms
-4m - 12 = 2m-6

collect the like terms and calculate
-4m-2m = -6+12

divide both sides by -6
-6m=6

m= -1

Find the coefficient of the x^3 in the expansion of (2x-9)^5

il63 [147K]

Use the binomial theorem:

$\displaystyle (2x-9)^5 = \sum_{k=0}^5 \binom5k (2x)^{5-k}(-9)^k = \sum_{k=0}^5 \frac{5!}{k!(5-k)!} 2^5 \left(-\frac92\right)^k x^{5-k}$
