Step-by-step explanation:

0 = x² - 6x - 27

a = 1, b = -6, c = -27 Factor using AC method.

ac = (1)(-27) = -27

Factors of -27 that add up to -6 are -9 and 3.

Therefore:

0 = (x - 9) (x + 3)

x = -3, x = 9

The x-intercepts are (-3, 0) and (9, 0).

What is -5x+6y=-12 in standard form

Ann [662]

$\mathfrak{\pink{\huge{Hello\:Mate!!!}}}$

$Answer$

$5x - 6y = - 12$

$Step-by-step explanation$

To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.

$Ax+By=C$

A must be positive, so multiply both sides of the equation by - 1.

Multiply - 1 by - 3x + 6y

-1 (-5x+6y) = - 1 × 12

Apply the distributive property.

-1 (-5x) - 1 (6y) = - 1 × 12

5x - 6y = - 12

What is the slope of this line? PLEASE HELP!!

Mars2501 [29]

Slope is rise over run (rise/run), your slope is 2/3.

This is because you go up 2 units(rise is up or down), and go to the right 3 units(run is left or right).

You can also use the slope formula:

$m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

and plug in points
