Answer:

x > - 3

Step-by-step explanation:

Given

3(x + 2) > x ← distribute left side

3x + 6 > x ( subtract x from both sides )

2x + 6 > 0 ( subtract 6 from both sides )

2x > - 6 ( divide both sides by 2 )

x > - 3

Coordinates (x, y)

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (5, -6)

Point (-3, 12)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-3-5)^2+(12+6)^2}$
[√Radical] (Parenthesis) Subtract/Add: $\displaystyle d = \sqrt{(-8)^2+(18)^2}$
[√Radical] Evaluate Exponents: $\displaystyle d = \sqrt{64+324}$
[√Radical] Add: $\displaystyle d = \sqrt{388}$
[√Radical] Simplify: $\displaystyle d = 2\sqrt{97}$

Please help w/ geometry!

lara [203]

Answer:

<XYZ = 34

Step-by-step explanation:

Remark

Bisected angles means that the original angle (<XYZ in this case) has been cut exactly in half. The two parts that were created from <XYZ are equal so you need only solve for x, solve one of the halves and then double it.

Equation

3x - 7 = 2x + 1

Solution

3x - 7 = 2x + 1 Add 7 to both sides

3x - 7+7 = 2x +1+7 Combine

3x = 2x + 8 Subtract 2x

3x-2x = 2x-2x + 8 Collect like terms on both sides

x = 8

Solution 2

Find one of the bisected parts. You can choose either of the two parts so use 2x + 1

2x + 1

2*8+1

16 + 1

WYZ = 17 degrees

Solution 3

Double <WYZ to get <XYZ

<XYZ = 2 * 17

<XYZ = 34 degrees
