This is late but as a guide for others it's:

Contraction: 0.9, 3/8

Expansion: 5, -6 , 8/5

Basically what they said but it made me confused at first. Just took the quiz. ^^

The values 5, 8/5 = 1.6 and -6 are all expansions because their absolute value is larger than 1. Note that |-6| = 6.

On the other hand, 0.9 and 3/8 = 0.375 are contractions because their distance from zero (aka absolute value) is less than 1.

5x − 3+ 2x = x + 7 + 6x

Masteriza [31]

Answer:

There isnt any solution.

Step-by-step explanation:

but these are the steps:

Step 1: Simplify both sides of the equation.

5x−3+2x=x+7+6x

5x+−3+2x=x+7+6x

(5x+2x)+(−3)=(x+6x)+(7)

7x+−3=7x+7

7x−3=7x+7

Step 2: Subtract 7x from both sides.

7x−3−7x=7x+7−7x

−3=7

Step 3: Add 3 to both sides.

−3+3=7+3

0=10

Find the value of 7x+2y when x=2 and y=-9

Nostrana [21]

Answer = -4

Step-by-Step Explanation:

Given: x = 2, y = -9

Therefore, substituting the values
= 7x + 2y
= 7(2) + 2(-9)
= 14 + -18
= 14 - 18
= -4

You have a ruler of length 2 and you choose a place to break it using a uniform probability distribution. Let random variable X

Dmitriy789 [7]

Hi!

When you break the rule for the first time, de probability distribution of X is constant in [0, 2], and is zero outside. If the the value obtained is X = a, then the probability distribution of Y (conditioned on X = a) is constaint in interval [0, a], and zero outside. Then the region in the X-Y plane where the joint density is non-zero is the filled triangle in the figure.
