Answer:
n E R
Step-by-step explanation:
Since 7n-8 is a linear equation with no restrictions, n's domain is real numbers.
Answer:
Centre: (4,3)
Radius: 2sqrt(2)
Step-by-step explanation:
h = -8/-2 = 4
k = -6/-2 = 3
4² + 3² - 17 = r²
r² = 8
r = sqrt(8) or 2sqrt(2)
sqrt: square root
In simplest form it would be 5/6 both can be divided by 2 which would equal 5/6
Answer:
Step-by-step explanation:
<u>The Sum:</u>
- 3x²y - 5a + 4b + (-9x²y - 7b + 4a) =
- 3x²y - 9x²y - 5a + 4a + 4b - 7b =
- -6x²y - a - 3b
<u>The difference:</u>
- 3x²y - 5a + 4b - (-9x²y - 7b + 4a) =
- 3x²y + 9x²y - 5a - 4a + 4b + 7b =
- 12x²y - 9a + 11b
<u>Subtract the sum from the difference:</u>
- 12x²y - 9a + 11b - (-6x²y - a - 3b) =
- 12x²y + 6x²y - 9a + a + 11b + 3b =
- 18x²y - 8a + 14b
