Determine whether The given segments have the same length. Justify your answer

Semenov [28]

We know the distance formula is

$\sqrt{ (x_{2}-x_{1})^2+ (y_{2}-y_{1})^2 }$

Here A( -4,2) and B(1,4)

So length of AB

= $\sqrt{(1-(-4))^2+(4-2)^2} =\sqrt{5^2+2^2} =\sqrt{29}$

Also C(2,1)

Length of BC

= $\sqrt{(2-1)^2+(-1-4)^2} =\sqrt{1^2+(-5)^2} =\sqrt{26}$

So we can see that length of AB is not equal to length of BC

11.

Now AB = $\sqrt{29}$

Also C(2,-1) & D(4,4)

Length of CD

= $\sqrt{(4-2)^2+(4-(-1)) ^2} =\sqrt{2^2+5^2} =\sqrt{29}$

Yes AB = CD

Solve the equation. −3(y+5)=15

e-lub [12.9K]

Divide both sides by -3

y + 5 = -15/3

Simplify 15/3 to 5

y + 5 = -5

Subtract 5 from both sides

y = -5 - 5

Simplify -5 - 5 to -10

y = -10

What is the answer to this question <br> 1/2 x -7=1/3(x-12)

timama [110]

Answer:

= 1 8 hope this helps!!! :)

Step-by-step explanation:

1 2 ⋅ −7 = 1 3 ( − 1 2 )

1 2 − 7 = 1 3 −1 2 )

1 2 − 7 = 1 3 − 1 2 )

Multiply by 1

Combine multiplied terms into a single fraction

Multiply by 1

Add to both sides of the equation

Enter the number that belongs in the green box.

ale4655 [162]

Answer:

the green box is 0

Step-by-step explanation:

we are asked to find the <u>x-intercept</u>, which means y = 0

(x, y)

Another way to test this is plug it in 1 for x! (1, y) where x = 1

$y = \frac{2x^{2} -3x+1}{2x^{2} +8x+6} \\\\$

$y = \frac{2(1)^{2} -3(1)+1}{2(1)^{2} +8(1)+6}$

$y = \frac{2(1) -3(1)+1}{2(1) +8+6}$

$y = \frac{2 - 3 + 1}{2 + 8 + 6}$

$y = \frac{-1+1}{10 + 6}$

$y = \frac{0}{16}$

y = 0
