Answer:

4x - 6y

Step-by-step explanation:

$\frac{2}{3} (6x - 9y) \\ \\ = \frac{2}{3} \times 6x -\frac{2}{3} \times 9y \\ \\ = 2 \times 2x - 2 \times 3y \\ \\ = 4x - 6y \\ is \: equivalent \: expression.$

Hey there!

Assuming that $"f" = y$

So, let's solve your function, shall we?

$y(-1) = 2 \\ \\ \\ -y= 2 \\ \\ DivideBy(-1) \\ \\ \\ \frac{-y}{1} = \frac{2}{-1} \\ \\ \\ CancelOut: \frac{-y}{1} \\ \\ \\ Keep: \frac{2}{-1} \\ \\ \\ \\ Answer: y = -2 (option D)$

Good luck on your assignment and enjoy your day!

Triangle ABC has vertices at A(−3, 4), B(4, −2), C(8, 3). The triangle translates 2 units up and 1 unit right. Which rule repres

Nataly [62]

Answer:

The translation statement is given by:

$(x,y)\rightarrow (x+1,y+2)$

After the translation, the coordinates of vertex A is (-2,6).

Step-by-step explanation:

Given :

Vertices of a triangle ABC are:

A(−3, 4), B(4, −2), C(8, 3)

The triangle is translated 2 units up and 1 unit right.

To find the co-ordinates of point A after translation.

Translation rules.

For shift of $c$ units up, the translation is given as:

$(x,y)\rightarrow (x,y+c)$

For shift of $k$ units right, the translation is given as:

$(x,y)\rightarrow (x+k,y)$

So, it says the triangles is translated 2 units up and 1 unit right.

The translation statement is given by:

$(x,y)\rightarrow (x+1,y+2)$

So, co-ordinates of point A after translation is given by :

$(-3,4)\rightarrow (-3+1,4+2)=(-2,6)$

After the translation, the coordinates of vertex A is (-2,6).

Adele Swam the length of the pool in 32.56 seconds. Alexandria swam the length of the pool in 29.4 seconds. How many seconds fas

Sati [7]

Answer

Find out how many seconds faster has Alexandria's time then Adele's time .

To proof

Let us assume that seconds faster has Alexandria's time then Adele's time be x.

As given in the question

Adele Swam the length of the pool in 32.56 seconds. Alexandria swam the length of the pool in 29.4 seconds.

Than the equation becomes

x = 32.56 - 29.4

x = 3.16 seconds

Therefore the 3.16 seconds faster has Alexandria's time then Adele's time .

Hence proved

F) As a truck driver, Roland averages 400 miles every 6 hours of driving. How long will it take him to drive

liubo4ka [24]

Answer:

31.5 hours

Step-by-step explanation:

time * speed = distance

speed=400/6=66.67 miles per hour

2100/(400/6)=31.5 hours
