Rounding is easy, just look at the number in the tenths place. If the number is less than 5 round down and if the number is greater than or equal to 5 round up.
7.58 x 10^-3 is the scientific notation
2t + 8 ≥ -4t - 4
2t+4t ≥ -8-4
6t ≥-12
t ≥ -12/6
t ≥ -2
Brackish water is shown as being 0.05 - 3%
2% falls in this range, so it would be Brackish water.
Answer:
Distance: 13, Midpoint: (-2, 3.5)
Step-by-step explanation:
The distance formula is 
. We can plug in the numbers from your question so it would be √(4+8)^2+(6-1)^2 = √144+25=169 =√169 = 13
The midpoint formula is ((x1+x2)/2, (y1+y2)/2), which is -8+4/2, 1+6/2 = (-2, 3.5).
