Answer from: allimaycatp8qgaq

C (Perpendicular)

Step-by-step explanation:

Non-coplanar: No on the same plane

Parallel: (Like train tracks) Never intersects at any point

Perpendicular: Intersects at some point (looks like a T at the intersection)

Skew: Lines aren’t parallel or intersecting

Answer from: xxaurorabluexx

Option C.

Step-by-step explanation:

Non - coplanar : If two lines do not lie on the same plane, then they are called non-coplanar lines.

Parallel lines : If the distance between two lines remains same and they never intersect each other, then they are called parallel lines.

Perpendicular line: If two lines intersect each other and form right angle, then they are called perpendicular lines.

Skew lines : If two lines lie on different plane and do not intersect each other, then they are called skew lines.

From the given figure it is clear that lines a and d lie on the same plane M and form right angle. So, lines a and d are perpendicular.

Therefore, the correct option is C.

Answer from: Quest

the system of inequity is

$y\leq -x+4$

$3y> x$

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

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

the solid line passing through the points (0,4) and (4,0).

$y-4=\frac{0-4}{4-0}(x-0)$

$y=-x+4$

the related equation of solid line is $y=-x+4$ .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

$y-0=\frac{0-1}{3-0}(x-0)$

$3y=x$

the related equation of dashed line is $3y=x$

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

$1=-0+4$

$1=4$

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be $\leq$ . the required inequality is

$y\leq -x+4$

similarly, check the second related equation.

$3(1)=0$

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

$3y> x$

15 points write a system of inequalities to represent the shaded portion of the graph
