In the triangles, XY = MP and YZ = PN. Triangles Y X Z and P M N are shown. The length of side X Z is 23 inches. The length of s
ziro4ka [17]

Answer:

m\angle Y = 85\°

Step-by-step explanation:

In Triangles YXZ and PMN

XY \cong MP\\YZ \cong PN

Since the third side of  triangle subtended by two congruent sides will always be congruent, the two triangles are congruent by SSS congruence theorem.

Therefore:\triangle XYZ \cong \triangle MPN\\

If the measure of angle P = 85°

Since P and Y are in the same positions(as seen in the diagram) in the two triangles respectively, the measure of angle Y is also 85 degrees.

Identify the vertex of the quadratic function in standard form y=2x^2 -16x+31
lapo4ka [179]

Answer:

(4,1)

Step-by-step explanation:

The vertex of the quadratic can be found using -b/2a. The vertex is the point (-b/2a, f(-b/2a)).

To find the x coordinate of the quadratic, define its a,b, and c. The quadratic has a = 2, b=-16, and c=31. Then -b/2a is -(-16)/2(2) = 16/4 = 4.

To find the y-coordinate, input the x=4 and solve for y.

y=2(4)^2-16(4)+31\\y=2(16)-64+31\\y=32-64+31\\y=1

The vertex is (4,1).

eimsori [14]

Answer:

(7, - 1)

Step-by-step explanation:

x = y + 8.....(1) \\  \\ x = 5y + 12....(2) \\  \\ from \: equations \: (1) \: and \: (2) \\  \\ 5y + 12 = y + 8 \\  \\ 5y - y = 8 - 12 \\  \\ 4y =  - 4 \\  \\ y =  \frac{ - 4}{4}  \\  \\ y =  - 1 \\  \\ plug \: y =  - 1 \: in \: equation \: (1) \\  \\ x =  - 1 + 8 \\  \\ x = 7 \\  \\ (x, \: y) = (7, \:  - 1)
