r-ruslan [8.4K]

Answer:

Step-by-step explanation:

Since ,AB is the mid segment of triangle LMN

Then

$\Longleftrightarrow AB=\frac{MN}{2}$

$\Longleftrightarrow x+8=\frac{5x+4}{2}$

$\Longleftrightarrow 2\times(x+8)=5x+4$

$\Longleftrightarrow 2x+16=5x+4$

$\Longleftrightarrow 16-4=5x-2x$

$\Longleftrightarrow 3x=12$

$\Longleftrightarrow x=\frac{12}{3}=4$

Your basketball team scored 4 fewer than twice as many points, x, as the other team. a. Write an expression for the number of po

velikii [3]

Answer:

A) p = 2x - 4 for the expression. B) Your team scored 44 points.

Step-by-step explanation:

Let <u>P</u> represent the points your team made.

Since the question says "Your basketball team scored 4 fewer than twice as many points as the other team." this is how I came up with the expression.

p = 2x - 4 ( our points = 2 times more then the other teams points minus 4.

Using this expression and the given information that the other team made 24 points, I solved B.

44 = 2(24) - 4.

Graphic image of the kite jklm after a reflection across the line Y= 1

olchik [2.2K]

Answer: see image

<u>Step-by-step explanation:</u>

Draw the line y = 1. Count how many units away the point is from that line. Move that point the same number of units in the opposite direction to create the reflection.

J is 2 units above y = 1. The new point is 2 units below y = 1. → (3, -1)

K is 3 units above y = 1. The new point is 3 units below y = 1. → (6, -2)

L is 5 units above y = 1. The new point is 5 units below y = 1. → (3, -4)

M is 3 units above y = 1. The new point is 3 units below y = 1. → (0, -2)
