Answer:
problem given: (-0.75x + 6) -(2.5x -1.9)
distribute: -0.75x+6 -2.5x-1.9
combine like terms: -0.75x-2.5x= -3.25x ; 1.9+6=7.6
solution: -3.25x+7.6
Answer:
Hey buddy, here is your answer. Hope it helps you.
Step-by-step explanation:
It is the difference between the dependent variable and a predicted value.Each data point has one residual. Residual = Observed value - Predicted value. A residual is a measure of how well a line fits an individual data point.
The ratios that have a unit rate of 5 will be:
6 1/4 kilometers to 1 1/4 minutes.
1 kilometer to 1/5 minutes
1/3 kilometers to 1 2/3 minutes
<h3>How to calculate the value?</h3>
The ratios will be:
1. 6 1/4 to 1 1/4
= 6.25 : 1.25
= 5
2. 4 1/2 to 2
= 4 1/2 / 2
= 2.25
3. 4/5 to 5 minutes
4. 1 kilometer to 1/5 minutes
= 1 : 1/5
= 1 / 0.2
= 5
5. 3 1/10 : 3/10
= 10
6. 1/3 : 1 2/3
= 5
Therefore, the correct options are 1, 4 and 6.
