Okay so you see those dots located in the fist question right? locate the coordinates ( 1, 2)

Now that you have located them, look at what the question asks

"move 3 units left and 7 units up" and what you do is move vertices ( 1,2) (aka the dot) 3 units left and move it up 7 times.

And now your new location for (1,2) should be (-2,5) because you moved the (1,2) dot 3 units to the left and 7 units up.

( now do the same for the rest of the other dots)

Shelly has a roll of fabric and decides to make some scarves for her friend the roll contains 6 2/3 yards of fabric she needs 5/

ivann1987 [24]

Answer:

Step-by-step explanation:

Total length of the fabric is $6\dfrac{2}{3}=\dfrac{20}{3}\ \text{yards}$

We need to find the number of scarves can she make if she needs 5/6 of a yard for each scarf.

Let she needs x scarves. So, ATQ

$x\times \dfrac{5}{6}=\dfrac{20}{3}\\\\x=\dfrac{20}{3}\cdot\dfrac{6}{5}\\\\x=8$

Hence, she can make 8 scarves.

To describe a sequence of transformations that maps triangle ABC onto triangle a"b"c", a student starts with a reflection over t

Paha777 [63]

i dont quite get the question but...

i guess this is how it is.

Take the mirror image of∆ABC Through the a line through the point y=3.

The new ∆ABC would have point C=(4,2)

B=(3,-6) A=(1,-3)

Now shifting the ∆ABC one unit (<em>i.e. 2 acc. to the graph as scale is 1 unit =2</em>) towards right ( or <em>adding 2 to the x coordinates of ∆ABC)</em>

We get the Coordinates of triangle ABC as A=(3,-3) B=(5,-6) C=(6,2).

This coordinate is the same coordinates of ∆A"B"C".

Hope it helps...

Express b+1/3b-2 with “b” as the subject

lara [203]

Answer:

b = $\frac{1+2a}{3a-1}$

Step-by-step explanation:

Given

a = $\frac{b+1}{3b-2}$ ( multiply both sides by 3b - 2 )

a(3b - 2) = b + 1 ← distribute left side

3ab - 2a = b + 1 ( subtract b from both sides )

3ab - b - 2a = 1 ( add 2a to both sides )

3ab - b = 1 + 2a ← factor out b from each term on the left side

b(3a - 1) = 1 + 2a ( divide both sides by 3a - 1 )

b = $\frac{1+2a}{3a-1}$

Ede4ka [16]

Answer:

Step-by-step explanation:

The first thing the man needs to do

Is to arrange the books by Abraham Lincoln amongst each other first. Now the number of ways the man can arrange these books amongst each other is a total of 4! Ways. Now there are 6 books remaining and there are also six slots remaining. The number of ways to arrange these six books within theirselves would be 6!

Now the total

Number of arrangements is 6! * 4!
