Mathematics

g(n) = 3n³ - 5           h(n) = 2n - 5              (g + h)(2) = g(2) + h(2)

g(2) = 3(2)³ - 5  = 3(8) - 5   = 24 - 5   = 19

h(2) = 2(2) - 5   = 4 - 5   = -1

g(2) + h(2) = 19 + -1   = 19 - 1   = 18

Answer: 18

Graph the solution set
antiseptic1488 [7]

Answer:

Graph by first drawing a horizontal line at 3 on the y axis. Anything below this line falls into the y is less than or equal to 3 range. Draw a vertical line at negative 2 on the x axis. This represents x > -2. The next one is a slanted line, so it'll be trickier to graph. If using a graph of 10 - 10, graph from (-8, -10) to (10, 8). If using a graph of 20 - 20, graph from (-18, -20) to (20, 18). As seen in the graph, anything to the upper left of this line is included.

The true inclusion is where all the ranges intersect. Be sure to color this the darkest or with a special pattern.

A line passes through the point (4,-9) and has a slope of -6. Write an equation in slope intercept form for this line
pishuonlain [190]

\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{-9})~\hspace{10em} \stackrel{slope}{m}\implies -6 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-9)}=\stackrel{m}{-6}(x-\stackrel{x_1}{4}) \\\\\\ y+9=-6x+24\implies y=-6x+15
