The answer is rational, because this number can be written as a over b
Answer:
There is a linear correlation between the number of doughnuts Homer eats and his weight. If Homer wants to lose weight, he should eat less doughnuts. If Homer graphed this relationship on a scatterplot, an increase on the y axis would lead to an increase on the x axis.
Step-by-step explanation:
Given that doughnuts have a high content of fat and sugar, they are well proved to be fattening foods. Indeed, one would expect that the more doughnuts are consumed per time unit, the more body weight will increase.
Mathematically, both variables (amount of doughnuts consumed and body weight) will behave the same way: an increase in one of them will led to an increase in the other one. The independent variable is the amount of doughnuts consumed by Homer (per unit time), as this is independent on anything else for this given problem, while the body weight is the dependent variable for its will respond to the increase in the amount of doughnuts consumed.
Graphically, the independent variable is plotted on the "<em>y</em>" axis, while the dependent variables is placed on the "<em>x</em>" axis.
Thus, when the relation between both variables is plotted, a straight-line relationships is expected. This is called a linear correlation, and it is interpreted as mentioned above: when the independent variable increases, the dependent variable increases as well, while a decrease in the independent variable leads to a decrease in the dependent one.
Let's solve the given equation ~
Hence, we get -6 and 1 as our roots ~
So, the correct choices are : B and D
Answer:
The 20% tip would be 18%
The 80% mark down would be 0.8 I think
The 60% I'm not sure for the 60% one
The 10% I'm not sure for that one but I think it would be 3.75
I think for 75% mark down it would be 0.7 I'm not sure tho and I'm not sure for the rest
Sorry if I'm wrong but hope this helps:)
Answer:
Q+ (5,-5)
Step-by-step explanation:
If the point is to be moved 5 units down, it means that its 'y' coordinate must be subtracted 5.
Same thing happens with x coordinate, it is moved 5 units to right, it meas that its 'x' coordinate must be summed with 5.
The whole operation can be written as the following addition:
Q + (5,-5)
