What is the slope of a line that contains the points (12,17) and (-8,-17)

professor190 [17]

$\frac{y2 - y1}{x2 - x1}$
$\frac{ - 17 - 17}{ - 8 - 12} = \frac{ - 34}{ - 20} = \frac{17}{10}$
Alternative forms:
$1 \frac{7}{10} \: or \: 1.7$
Slope: 17/10
Equation : y= 17/10x

Answer:

-30x^2-9x+12 all real numbers

Step-by-step explanation:

f(x) = -6x + 3 and g(x) = 5x + 4

f(x) * g(x) = (-6x + 3) * ( 5x + 4)

FOIL

= -30x^2 -24x+15x +12

Combine like terms

=-30x^2-9x+12

The domain is what numbers x can take

There are no restrictions so all real numbers
