Answer: A. Figure ABCD is similar to figure A'B'C'D'.

Step-by-step explanation:

Given : Figure ABCD is reflected about the x-axis to obtain figure A'B'C'D'.

Since a reflection is a rigid transformation which produces congruent images.

⇒ Figure ABCD must be congruent to figure A'B'C'D'.

⇒ Figure ABCD has same size as figure A'B'C'D'.

⇒ Figure ABCD must be similar to figure A'B'C'D'.  [ ∵ If two figures are congruent then they are also similar.]

Reflection preserves side length and measure of angles .

⇒ Corresponding angles and side lengths of figure ABCD must be congruent to figure A'B'C'D'.

⇒ The measure of angle D is equal to the measure of angle D'.

Hence, the statement best describes the relationship between the two figures is :-

A. Figure ABCD is similar to figure A'B'C'D'.

The  best approximation for the solution to this system of equations is (-2.2,-3)

Option C is correct.

Step-by-step explanation:

Solving the system of equations to get the exact value of x:

y = -3\\y = x-0.8

Let

y = -3\,\,eq(1)\\y = x-0.8\,\,eq(2)

Putting value of y from eq(1) into eq(2)

-3=x-0.8

x=-3+0.8

x=-2.2

So, Value of x is -2.2

The  best approximation for the solution to this system of equations is:

x=-2.2 and y = -3

(-2.2,-3)

Option C is correct.

From Midnight to 6 am the temperature rose 8 degrees C. At 6 am the temperature was -21 degrees C. What was the temperature at m
Alika [10]
Hello!

We know that from midnight to 6am the temperature went up 8° and at 6am it was -21°

To find what it was at midnight we have to work backwards

Since it went up we have to subtract 8 from -21

-21 - 8 = -29

The answer is -29°C

Hope this helps!

The figure below is made of 2 rectangular prisms.<br><br>What is the volume of this figure?
mixer [17]

Answer:

6536 cubic in

Step-by-step explanation:

1. Split both the prisms apart- In doing so, you can simplify the problem.

2. Put in the #'s for the formula which in this case is V=L*W*H, we will start with the formula for the front one, V=7*8*1 or V=7*8

3. answer for the front is 56 cubic in, now we solve for the other half.

4. V=9*1*90 or V=9*90 which is 6480 cubic in.

5. add 6480 and 56 and your answer is 6536 cubic in as your answer.

Hope this helped ;D
