Answer: y−3=−3y−43

Step 1: Add 3y to both sides.

y−3+3y=−3y−43+3y

4y−3=−43

Step 2: Add 3 to both sides.

4y−3+3=−43+3

4y=−40

Step 3: Divide both sides by 4.

4y

4

=

−40

In the Changing Dimensions of 3D Figures
den301095 [7]

Answer:factor of 9

Step-by-step explanation:

Given

prism were changed by a scale factor of 3

Suppose prism is rectangular in shape

So surface are is S.A.=2(lw+wb+lb)

Where l=length

w=width

b=breadth

So new length,breadth and width is

l'=3l

w'=3w

b'=3b

S.A.=2(3\times 3lw+3\times 3wb+3\times 3lb)

S.A.=2\times 3^2(lw+wb+lb)

S.A.=3^2\times 2(lw+wb+lb)

So new surface area would change by a factor of 9

What is the order of rotational symmetry for the figure
Kaylis [27]

Answer:

B. 3

Step-by-step explanation:

First of all we will define rotational symmetry.

Rotational symmetry is when a shape looks the same after some rotation or less than one rotation.

The order of rotational symmetry is how many times it matches the original shape during the rotation.

So, for the given shape the rotated shape will match the original shape three times so the order for symmetry for the given shape is 3.

Hence,

the correct answer is B. 3 ..
