Answer:
-4y + 20
Step-by-step explanation:
4(-y+5)
What we need to do here is get rid of the parentheses, which can be achieved through multiplication.
This is another way of saying 4 times -y plus 4 times 5.
Let's break the the parentheses down into 2 separate formulas.
4(-y) and 4(5)
Now we can multiply these two together to get -4y and +20. When combined, we get -4y +20.

Answer:
He did not control for lurking variables and their impacts on the results of his experiment. Amount of sunlight and water received are two outside variables(or confounding variables) that may impact the growth of his plants and influence the results. He needs to apply the same amount of sunlight and water to each plant within a different planting soil in order to rule out the influence of those two variables and test the sole effect of the soil brand on the plant growth. Otherwise, it would be hard to determine whether his plant growth was because of the soil brand or the different amounts of sunlight and water received

Answer:
2
Step-by-step explanation:
x f(x)
−3 −1.5
−2 −1
−1 −0.5
0 0
1 0.5
2 1
3 1.5
This table shows the input and output values for a linear function f(x).
Now, two inputs which are four values apart are say -3 and 1 and the corresponding outputs are - 1.5 and 0.5.
Therefore, the positive difference of outputs is [0.5 - (- 1.5)] = 2 (Answer)
