Answer:

Step-by-step explanation:

(x+6)(x+4)(x-3)

= [(x+6)(x+4)](x-3)

= (x² + 4x + 6x + 24)(x - 3)

= (x² +10x + 24)(x - 3)

= x³ - 3x² + 10x² - 30x + 24x - 72

= x³ + 7x² - 6x - 72

Answer:

x^3 +7x^2 - 6x - 72.

Step-by-step explanation:

(x + 6)(x + 4)(x - 3)

= (x + 6)[x(x - 3) + 4(x - 3)]

= (x + 6)(x^2 - 3x + 4x - 12)

= (x + 6)(x^2 + x - 12)

= x(x^2 + x - 12) + 6(x^2 + x - 12)

= x^3 + x^2 - 12x + 6x^2+ 6x - 72

= x^3 +7x^2 - 6x - 72.

Graph the line passing through (−2,5) whose slope is m=1/5
Nonamiya [84]

Hello there! :)

Given:

x-coordinate of point = -2

y-coordinate of point = 5

Slope, or "m" = 1/5

Substitute in these values into slope-intercept formula (y = mx+b)

5 = 1/5(-2) + b

5 = -2/5 + b

25/5 = -2/5 + b

27/5 = b

Rewrite the equation:

y = 1/5x + 27/5

Graph the equation using a graphing utility:
