Answer:
The second number would be 8 or 16
Step-by-step explanation:
Let x be the unknown number,
Since, first number = 17,
So, the difference between x and 17 = |17 - x |
According to the question,
|17 - x | = 9
17 - x = ± 9
17 - x = 9 or 17 - x = -9
17 - 9 = x or 17 + 9 = x
⇒ x = 8 or x = 26
Hence, the second number would be 8 or 26.
Answer:
n = 13.
Step-by-step explanation:
Slope of the line = (10-1)/3-0) = 3
So the equation of the line is:
y - 1 = 3(x - 0)
y = 3x + 1
When x = 4 y = n, so:
n = 3(4) + 1 = 13.
n = 13.
Sin55 = x/26
26sin55 = x
x = 21.298
Step-by-step explanation:
Transformations are resizing, translating, rotating, and reflecting a shape about the origin.
For this case, the first thing to do is find the equation of the line in order to model the problem mathematically.
Using Excel (see attached image) we find that the equation of the line is:
y = 0.0035x - 3 We evaluate for:
For x = 7000: y = 0.0035 * (7000) - 3
y = 21.5 $
For x = 10000 y = 0.0035 * (10000) - 3
y = 32 $
For x = 13000 y = 0.0035 * (13000) - 3
y = 42.5 $
Answer: The total water cost when the barber shop uses 7,000 gallons, 10,000 gallons, and 13,000 gallons is: 21.5 $, 32 $, 42.5 $, respectively.
