Co-ordinates of point B" are (-8,6)

Step-by-step explanation:

Question:

Suppose the point (2,8) is reflected across the −axis and then translated according to the rule (, ) → (, + 4). What are the coordinates of ′′? Show your work and explain.

Solution:

We are given the point B(2,8) and we need to find B".

The coordinates of B" will be:

a) The point B(2,8) is reflected across the −axis:

If a point is reflected across x-axis, then the co-ordinate of x-axis remains same, while co-ordinate of y-axis is changed into opposite value, i.e its sign is changed.

So, point B' will be (2,-8)

b) Now, point B' is translated according to the rule (, ) → (, + 4) so, co-ordinates of point B'' are:

So, y= -8 and x = 2

(-8,2+4)

(-8,6)

So, Co-ordinates of point B" are (-8,6)

Hello!

<u><em>Answer: </em></u>

_________________________________________________

Explanation: This question's it's about the order of operations. It stands for p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right. (PEMDAS)

1. -4(3-1)+2

Do parenthesis first.

$(3-1)=2$

$-4*2+2$

Then do multiply left to right.

$-4*2=-8$

Add left to right.

$-8+2$

$8-2=6$

*Answer should be have negative sign.*

Answer: → $\boxed{=-6}$

______________________________________________________

2. 3⋅[(30−8)÷2+2]

Do parenthesis first.

$(30-8)=22$

$22/2+2$

Then divide left to right.

$22/2=11$

Add left to right.

$11+2=13$

Multiply left to right.

$3*13=39$

*Answer should be have positive sign.*

Answer: → $\boxed{=39}$

_____________________________________________________

3. 14(1-23)2+13

Do parenthesis first.

$(1-23)=-22$

$14(-22)*2+13$

Then, you multiply left to right.

$14(-22)=-308$

$-308*2=-616$

Add/subtract left to right.

$-616+13$

$616-13=603$

*The answer must be have a negative sign*

Answer: → $\boxed{=-603}$

Hope this helps!

Thank you!

Have a great day!

julia puts her stickers into arrays in an album. some of her stickers are animal stickers. there are a different number of stick

lina2011 [118]

The total number of stickers :

Page 1 : 28

Page 2 : 24

Page 3 : 72

Page 4 : 48

<h3>Further explanation </h3>

There are several properties in integer multiplication operations

1. closed property

Multiplication between integers will produce integers too

2. commutative property

a x b = b x a

3. associative property

ax (bxc) = (axb) xc

4. identity

ax1 = 1 x a = a

5. distributive property

* addition

ax (b + c) = axb + axc

* substraction

ax (b-c) = axb - axc

We can use facts to solve multiplication problems

for example :

6 x 7 = (5 x 7) + ( 1 x 7) = 42

we can break facts with 6 into 5s and 1s facts from multiplication above

julia puts her stickers into arrays in an album

From picture (attached) we can find the total number of stickers on each page with 1s,2s,3s and 5s facts

Page 1 : 4 x 7 = (2 x 7) + ( 2 x 7) = 14 + 14 = 28
Page 2 : 4 x 6 = (1 x 6) + (3 x 6) = 6 + 18 = 24
Page 3 : 8 x 9 = ( 3 x 9) + (5 x 9) = 27 + 45 = 72
Page 4 : 8 x 6 = (3 x 6) + (5 x 6) = 18 + 30 = 48
