Answer:
see explanation
Step-by-step explanation:
Complementary angles sum to 90°, thus
∠A ∠B = 90 ← substitute values
5x - 27 + 4x - 27 = 90, that is
9x - 54 = 90 ( add 54 to both sides )
9x = 144 ( divide both sides by 9 )
x = 16
Hence
∠A = 5x - 27 = (5 × 16) - 27 = 80 - 27 = 53°
∠B = 4x - 27 = (4 × 16) - 27 = 64 - 27 = 37°
The answer would be A 7000$. Hope that helped!
Answer:
94.15
Step-by-step explanation:
15.5 x 3.5= 54.25
22.8 x 1.75= 39.9
54.25+39.9=94.15
Hello!
To first understand this question, we have to know what a domain is, and what it means to be linear.
The domain is all the possible x values.
Currently, in this graph, it starts at 0, and goes to some point further on.
To be linear means that you have linear growth, which this does not. This has a bend in it, which is not linear.
So, you must restrict the domain such that you only have a linear section.
If you look at the graph as a whole, it makes a bend. But, if you only look at x value 6 and up, it seems quite straight.
So, this makes sense!
Hope this helps, feel free to ask questions in comments.
