marin [14]
The distance between two points (x₁,y1),(x₂,y₂) is d
d= \sqrt{(x2-x1)^2 + (y2-y1)^2}

For the given problem we have
<span>W(1,8),X(7,8),Y(4,5), and Z(1,2)

The length of WY = </span>\sqrt{(4-1)^2 + (5-8)^2} = 3√2
The length of WX = \sqrt{(7-1)^2 + (8-8)^2} = 6
The length of WZ = \sqrt{(1-1)^2 + (2-8)^2} = 6
The length of XY = <span><span>\sqrt{(4-7)^2 + (5-8)^2} = 3√2
</span>The length of ZY = </span><span>\sqrt{(1-4)^2 + (2-5)^2} = 3√2

∴ WX = WZ  ⇒⇒⇒ proved
    XY = ZY   ⇒⇒⇒ proved
    WY = WY  ⇒⇒⇒ reflexive property

∴ Δ</span><span>WYZ is congruent to ΔWYX by SSS method</span>

Which inequality is true? Use the number line to help. A number line going from negative 2.5 to positive 2.5 in increments of 0.
alexgriva [62]

Given:

A number line going from negative 2.5 to positive 2.5 in increments of 0.5.

To find:

The inequality which is true.

Solution:

Consider the number line as shown in the below figure.

We know that, on a line as we go to the left direction, the number become smaller and as we go right, the numbers become larger.

From the number line it is clear that -1.5 is on the left side of 0.5. So,

-1.5

Hence, option A is incorrect.

-0.5 is on the left side of 0. So,

-0.5

Hence, option B is incorrect.

-1.5 is on the left side of -0.5. So,

-1.5

Hence, option C is correct.

One half is equal to 0.5.

\dfrac{1}{2}=0.5

Hence, option D is incorrect.

Step-by-step explanation:

even numbers are 3

3/6=1/2

1/2=1/2

1 or 5=2 numbers

2/6=1/3

1/3=1/3

numbers < 3 are 1 and 2

2 numbers

2/6=1/3

1/3 does not =1/2

2 or odd numbers are 2,1,3,5

4/6=2/3

2/3=2/3
