Solve this system of linear equations. Separate the x- and y- values with a comma.

liubo4ka [24]

Answer:

(-1,4)

Step-by-step explanation:

Using elimination, add the two equations to get rid of the y variable.

17x = 43 - 15y

+8x = -68 + 15y

=25x = -25

Now plug in -1 for x in any of the equations.

17(-1) = 43 - 15y

-17 = 43 - 15y

-60 = -15y

YS is the perpendicular bisector of XYZ and YS is a shared side of XYS and ZYS. which of the following must be congrent in order

german

Answer:

The triangles SYX and SYZ are congrient so by CPCTC $XY\cong YZ$ , $XS\cong ZS$ and $\angle X\cong \angle Z$ .

Step-by-step explanation:

Given information: YS is the perpendicular bisector of XYZ.

In triangle YXS and triangle YSZ,

$\angle SYX=\angle SYZ$ (YS is the perpendicular bisector of XYZ)

$YS=YS$ (Common side, Reflexive property)

$\angle YSX=\angle YSZ=90^{\circ}$ (YS is the perpendicular bisector of XYZ)

By ASA postulate,

$\triangle SYX\cong \angle SYZ$

The corresponding parts of congruent triangles are congruent. so,

$XY\cong YZ$

$XS\cong ZS$

$\angle X\cong \angle Z$
