Which inequality matches the graph?

Papessa [141]

Given:

The dotted boundary line passes through the points (-3,-8), (1,-2) and (9,10).

Above line is shaded.

To find:

The inequality for the given graph.

Solution:

Consider any two points on the line. Let the two points are (1,-2) and (9,10). So, the equation of the line is:

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-(-2)=\dfrac{10-(-2)}{9-1}(x-1)$

$y+2=\dfrac{10+2}{8}(x-1)$

$y+2=\dfrac{12}{8}(x-1)$

$y+2=\dfrac{3}{2}(x-1)$

Multiply both sides by 2.

$2(y+2)=3(x-1)$

$2y+4=3x-3$

$2y-3x=-3-4$

$-3x+2y=-7$

Above line is shaded and the boundary line is a dotted line. So, the sign of inequality must be >.

$-3x+2y>-7$

This inequality is not in the equations. So, multiply both sides by -1 and change the inequality sign.

$(-3x+2y)(-1)$

$3x-2y$

Therefore, the correct option is D.

Find the distance between (6,2) and (9,12)

bazaltina [42]

Distance bweteen (x1,y1) and (x2,y2) is
$D= \sqrt{(x2-x1)^2+(y2-y1)^2}$

so disatnce between (6,2) and (9,12) is
$D= \sqrt{(9-6)^2+(12-2)^2}$
$D= \sqrt{(3)^2+(10)^2}$
$D= \sqrt{9+100}$
$D= \sqrt{109}$

the distance is√109 units

6x-12=2x-6 <br><br> Also,how do you check your answer?

taurus [48]

6x-12 = 2x-6

get like terms on the same side by adding/subtracting.

6x - 12 = 2x - 6
+ 12, -2x on both sides

6x - 2x = -6 + 12

4x = 6

divide all by 4

x = 1.5

to check your answer, plug in 1.5 for x and see if they are equal to one another.

6(1.5) - 12 = -3
2(1.5) - 6 = -3
