Which statement best explains whether △JKL is congruent to △MNP?
Alchen [17]
Rotation of triangle JKL by 180 degrees will result in a triangle with corresponding vertices of (2, 4), (3, 2) and (-1, 2).

Then translating the resulting triangle 2 units up will result in a triangle with corresponding vertices (4, -2), (2, -3) and (2, 1) which is the same triangle as the given triangle MNP.

Therefore, the statement that best explains whether △JKL is congruent to △MNP is △JKL is congruent to △MNP because △JKL can be mapped to △MNP by a rotation of 180° about the origin followed by a translation 2 units up.

QUESTION ATTACHED PLZ HELP NEEDED
saw5 [17]
Y = a (x + 3)² - 1

Let's take the point (-1;3)

3 = a ( -1 + 3)² - 1
3 = 4a - 1
4a = 4

Therefore a = 4/4 = 1

(x+3)² - 1
= x² + 6x + 9 - 1
= x² + 6x + 8

The answer would be y = x² + 6x + 8.

Hope this helps !

Help please! math assignment
MArishka [77]

Answer:

The left side   5

The bottom  10

The slanted side  11

Step-by-step explanation:

To find the perimeter of the triangle, add up the side lengths

x+ 2x+1 + x+5 = 26

Combine like terms

4x+6 = 26

Subtract 6

4x+6-6 =26-6

4x=20

Divide by 4

4x/4 = 20/4

x=4

The left side  x = 5

The bottom  x+5    = 5+5 = 10

The slanted side  = 2x+1 = 2*1 +1 = 10+1 =11
