2) Line segment MK has endpoints at (2, 3) and (5, ?4). Segment M'K' is the reflection of MK over the y-axis. Which statement de
Marianna [84]

Answer:

Option C -M'K' is the same length as MK

Step-by-step explanation:

Given : Line segment MK has endpoints at (2, 3) and (5,4)

               M'K' is the reflection of MK over the y-axis

By definition of reflection: reflection of point (x,y) across the the y-axis is the point (-x,y)

which implies M'K' has end points (-2,3) and (-5,4)

Now, we find the length of MK

let (x_1,y_1)=(2,3)\\\\(x_2,y_2)=(5,4)

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

⇒ d=\sqrt{(2-5)^2+(4-3)^2}

⇒d=\sqrt{9+1}

⇒d=\sqrt{10}   ....(1)

Now, we find the length of M'K'

let (x_1^{'},y_1^{'})=(-2,3)\\\\(x_2^{'},y_2^{'})=(-5,4)

d^{'}=\sqrt{(x_2^{'}-x_1^{'})^2+(y_2^{'}-y_1^{'})^2}

⇒ d^{'}=\sqrt{(-2+5)^2+(3-4)^2}

⇒d^{'}=\sqrt{9+1}

⇒d^{'}=\sqrt{10} .....(2)

from (1) and (2) we simply show that the length of MK and M'K' is equal

we can also refer the figure attached for reflection of MK and M'K'

therefore, Option C is correct

The equation of the graphed line is x+2y=5. What is the x-intercept of the graph?
Nady [450]

Answer:

x = (5,0)

Step-by-step explanation:

To find the x-intercept, substitute y with 0 and solve for x.

x + 2(0) = 5

Then, simplify.

Multiply 2 by 0.

x + 0 = 5

Add x and 0.

x = 5

So, the result will be x = (5,0)

What is the answer ?
Lelechka [254]

Answer:

option C = (x+2)(x+1)

Option D = 3x^2+2x

Step-by-step explanation:

option C

(x+2)(x+1)= x*x+x+2x+2

(x+2)(x+1)= x^2 +3x + 2

X^2 : squared term

Option D = 3x^2+2x

3x^2 : squared term

All of them are wrong except number 12. The top left is 7, the top right is 26, the bottom left is 4. And a little hint, do what's in the parentheses first. Hope I helped!!
