Answer:

x>-3

Step-by-step explanation:

1: write out the problem - x+2 1/2>-1/2

2: subtract 2 1/2 from both sides - x>-3

3: write your answer - x>-3

4: graph on a number line - to do this draw a number line with hashes, -5 to 5 or so would probably be fine, and draw on open circle on -3, then bold the number line on the right side of the circle.

Given the points P(2,-1) and Q(-9,-6), what are the coordinates of the point on directed line segment PQ that partitions PQ in t

gayaneshka [121]

ANSWER

$( - \frac{23}{5} , - 4)$

EXPLANATION

Given the points P(2,-1) and Q(-9,-6),the coordinates of the point that partition the directed line segment PQ in the ratio 3:2 is given by

$x = \frac{ mx_2+nx_1}{m + n}$

$y= \frac{ my_2+ny_1}{m + n}$

Where m=3 and n=2

$x = \frac{ 3 ( - 9)+2(2)}{3+ 2}$

$x = \frac{ - 23}{5}$

$y= \frac{ 3( - 6)+2( - 1)}{3 + 2}$

$y= \frac{ - 20}{5} = - 4$

The point is

$( - \frac{23}{5} , - 4)$

15d^3+30d^2+30d/3d3 what is the answer if you divide the following

lawyer [7]

When you separate them
$\frac{15d^{3} }{ {3d}^{3} } + \frac{30d^{2} }{ {3d}^{3} } + \frac{30d }{ {3d}^{3} } = x$
Solve them separately:
$5 + \frac{10}{d} + \frac{10}{ {d}^{2} } = x$
Remove the denominators:
$5 + 10 {d}^{ - 1} + 10 {d}^{ - 2} = x$
Find GCF (Greatest Common Factor):
$5(1 + 2 {d}^{ - 1} + 2 {d}^{ - 2} ) = x$
