ANSWER
y = 2/3x + 15
Explanation:
Equation used: y - y1 = m( x - x1 )
y - 9 = 2/3 ( x - -9 )
y - 9 = 2/3x + 6 ( distribution )
y - 9 = 2/3x + 6 ( add 9 to 6 )
y = 2/3x + 15
First, you have to find the unit rate by dividing
2000/6=333.33 but round it up to 333
So the unit rate is 333 bacteria per hour
Then, you have to multiply
333x16= 5,328 bacteria after 16 hours
The answer is that in 16 hours, there will be 5,328 bacteria

The weight of each small tables and chairs in the United States is 15lbs and 3.5lbs respectively.
<h3>Simultaneous equation</h3>
Let
- Weight of tables = x
- Weight of chairs = y
- Cost of 3 tables and 5 chairs is 62.5lbs
- Cost of 3 tables and 2 chairs is 52lbs
3x + 5y = 62.5
3x + 2y = 52
- Subtract the equation to eliminate x
5y - 2y = 62.5 - 52
3y = 10.5
y = 10.5/3
y = 3.5 lbs
Substitute y = 3.5 into
3x + 2y = 52
3x + 2(3.5) = 52
3x + 7 = 52
3x = 52 - 7
3x = 45
x = 45/3
x = 15 lbs
Therefore, the weight of each small tables and chairs in the United States is 15lbs and 3.5lbs respectively.

For this case, we have the total of painters is 16, so to determine what percentage is painting the interior of the house, we make a rule of three:
16 ---------------> 100%
4 -----------------> x
Where "x" represents the% of painters who paint the interior of the house.
Thus, 25% of painters are painting the interior of the house.
Answer:
25%
4- y=-3/2 +4
Because 2/3 has to be flipped and change the sign so it would be -3/2. But I am not sure about the y-intercept. I just went with the slope in this case.
Hope it helps!
