Math help !! :o <br> will reward<br> written response questions :3

In the picture with the triangles Phillip is correct because the triangle does not give the measurements of the same side so there is no proof of any sides to be the same. With the other picture what I did was I reversed the translation which got the points A (-2,1) B (-5,3) Then I reversed the rotation which got me A(2,-1) and B (5,-3). So line AB endpoints would be located A (2,-1) and B (5,-3).

Hope this helps!

Jen picked three fourth in half an hour if she keeps the same rate how many will she pick in 2 hours

Sunny_sXe [5.5K]

Alright, lets get started.

Jen picked three fourth in half an hour.

Half an hour means 30 minutes.

At the same rate, how many she can pick in 2 hours.

2 hours means $2 * 60 = 120$ minutes

Now,

In 30minutes, Jen can pick = $\frac{3}{4}$

In 1 minute, Jen can pick = $\frac{3}{4} *\frac{1}{30}$

In 120 minutes, Jen can pick = $\frac{3}{4} *\frac{1}{30} * 120 = 3$

Hence Jen can pick complete 3 in 2 hours of time.

So the answer is 3 : Answer

Hope it will help :)

Determine if line KM and line ST are ॥, ⊥, or neither: K(-5,1) , M(-2,-8), and S(12,14), T(20,-10) Parallel Perpendicular or nei

Black_prince [1.1K]

Answer:

The lines are parallel i.e. KM || ST

Step-by-step explanation:

Given

K(-5,1) , M(-2,-8), and S(12,14), T(20,-10)

In order to find if the lines are parallel, perpendicular or neither slope will be used.

The slope of any line which passes from two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by the formula

$m = \frac{y_2-y_1}{x_2-x_1}$

If two lines are parallel their slope is equal. If two lines are perpendicular the product of their slope is equal to -1

So, first slopes of both lines will be calculated.

Let m1 be the slope of KM

and

m2 be the slope of ST

<u>In case of KM:</u>

$(x_1,y_1) = (-5,1)\\(x_2,y_2) = (-2,-8)$

Putting the values in the formula for slope

$m_1 = \frac{-8-1}{-2-(-5)}\\m_1 = \frac{-9}{-2+5}\\= \frac{-9}{3}\\= -3$

<u>In case of ST:</u>

<u></u> $(x_1,y_1) = (12,14)\\(x_2,y_2) = (20,-10)$ <u></u>

Putting the values in the formula for slope

$m_2 = \frac{-10-14}{20-12}\\= \frac{-24}{8}\\= -3$

As we can see that slope of both lines KM and ST are equal

i.e. m1 = m2 = -3

Hence,

The lines are parallel i.e. KM || ST
