Answer: C

Step-by-step explanation: As you most likely know, the matrix represents the system of equations. If you assume that x is the far left column, that y is the column adjacent to it, and that y is to the left of the line, you can assume that these are the equations represented:

1x-3y+2z=-9

1x+0y+1z=1

0x+2y-1z=7

which can be simplified to

x-3y+2x=-9

x+z=1

2y-z=7

Is 6 a solution of x-8=-2
Sidana [21]
Yes, because you move the 8 over, the negative gets cancelled. Meaning -2+8 and that makes 6.

USPshnik [31]

v is 4 more tha x

v=4+x

sum is no more than 14

v+x≤14

sub 4+x for v

4+x+x≤14

4+2x≤14

minus 4 both sides

2x≤10

divide both sides by 2

x≤5

5+4=9

Why don't parallel lines exist in elliptical geometry?
tiny-mole [99]
Parallel lines don't exist in elliptical geometry because elliptic geometry, a special case of Riemannian Geometry, is a non Euclidean geometry, in which, given a line L and a point P outside L, there exists no parallel lines because all the elliptical lines intersect.

What is the measure of the corresponding central angle for XY in radians?
beks73 [17]

Answer:

4 radians

Step-by-step explanation:

Arc Length (Radians) = rθ

Given Arc Length XY  = 40cm and radius, r = 10cm,

we will substitute these 2 values into the formula to find θ.

(10)θ  = 40

θ = 40 / 10

= 4 radians

What is the measure of each exterior angle of a decagon?
NemiM [27]
The sum of all of the exterior angles of any regular polygon is 360  (I'm assuming by decagon you mean a regular dodecagon).

Because the total has to be 360, and a decagon has 10 sides, you divide 360 by 10 to get each exterior angle.

360 ÷ 10 = 36, so each exterior angle of a decagon is 36 degrees.
