Answer:
Step-by-step explanation:
A vertical stretch by a factor of k means that the point (x, y) on the graph of f (x) is transformed to the point (x, ky) on the graph of g(x), where k <1.
If k =1, then same graph we obtain and if k>1 we get a vertically shrink graph.
In our question, there is a vertical stretch of 3. This means new graph would have points as (x,y/3)
i.e. instead of f(x) = y, we have now f(x) = y/3
So transformation is g(x) = 3f(x)
Option A is correct.
2) Here f(x) = 3x+8 is transformed to g(x) =3x+6
i.e. y intercept is reduced by 2 units. Hence there is a translation of 2 units down.
With only the description, my answer is 20 students.
For this case defining variables we have:
x: total amount of liters of potting soil.
y: number of liters of potting soil in each pot.
We have then to find the number of pots we use the following expression:
Substituting values we have:
Rewriting we have:
Rounding to the previous whole we have:
Answer:
Yao Xin can fill 18 pots
Answer:
-5x-10 is the expression. the missing values would be 2 and -x i believe
