Graph: 20x + 3.00y is greater than or equal to 500
hram777 [196]

Do you mind if I re-arrange it slightly before we solve it ?

         You said     20x  +  3.00y  ≥  500

Subtract  20x
from each side:               3.00 y  ≥  -20x + 500

Divide each side by  3 :          y  ≥  -20/3 x  +  500/3

Make it an equation,
and graph this line:                  y  =  -20/3 x  +  500/3

The line is made out of all points where 'y' is EQUAL to
1/3 of (-20x + 500).

The inequality wants to see all the points that are equal to it
AND all the points that are greater than that.

So the graph of the inequality is the line AND every point that's
anywhere above the line.  It's called the "half-infinite plane"
bounded by the line.

Choose the correct simplification of the expression (2x-6)(3x^2-3x-6)
timama [110]

Answer:

A.  6x^3 - 24x^2 + 6x + 36.

Step-by-step explanation:

(2x - 6)(3x^2 - 3x - 6)

= 2x(3x^2 - 3x - 6) - 6(3x^2-3x-6)

=  6x^3 - 6x^2 - 12x - 18x^2 + 18x + 36

Simplifying like terms:

=  6x^3 - 24x^2 + 6x + 36 (answer).

Robert works in a toll booth. About 18 to 23 cars pass through Robert's booth every 23 minutes. Which is a reasonable estimate f
BARSIC [14]

A reasonable number between 18 and 23 is 20. 69 minutes is 3 times 23 minutes, so we multiply the 20 by 3, getting an estimate of 60 cars.
