Answer:
See below
Step-by-step explanation:
<u>Given:</u>
- f(x)= { 3x+1, if −9 < x ≤ −2
- f(x)= {−5, if. −2 < x ≤ 1
- f(x)= { x−6, if 1 < x < 7
<u>Combination of domain for the function is the following union:</u>
- (-9, 2]∪ (-2, 1]∪(1, 7) = (-9, 7)
<u>Group of answer choices:</u>
The domain is the depth interval (−26, 1).
- incorrect as (-26, -9) interval is not covered in given function
The domain is the depth interval (−9, 1].
The domain is the set of times −9 < x < −2, −2 < x < 1, and 1 < x < 7.
- incorrect as doesn't include x = -2 and x = 1
The domain is the time interval (−9, 7).
- This is correct as it is same with the domain set we got above.

Answer:
18ft
Step-by-step explanation:
If every cube is 1/4th foot in volume, then 4 cubes would be equivalent to 1ft. The box we need to measure is 4 cubes high, we can just count how many little cubes are on the top side and the amount of cubes would be at a 1 to 1 with how many square feet in volume the box is.
I'm not confident in this explanation but id be happy to answer questions in comments.
Hope i helped!
Answer: A sequence of similar transformations of dilation and translation could map △ABC onto △A'B'C'.
Step-by-step explanation:
Similar transformations: If one figure can be mapped onto the other figure using a dilation and a congruent rigid transformation or a rigid transformation followed by dilation then the two figures are said to be similar.
In the attachment △ABC mapped onto △A'B'C' by a sequence of dilation from origin and scalar factor k followed by translation.
