Which is one of the transformations applied to the graph of f(x) = x2 to change it into the graph of g(x) = 9x2 – 36X?
Fiesta28 [93]
Assuming I understand your question correctly, in that you’re looking for just some descriptions of the differences between the functions. If so, then I’d say:

First graph both functions, the f(x) and the g(x). Then spot the differences.
Note that the g(x) function has shifted towards the right compared with the f(x) function.
Another way that the g(x) differs from the f(x) function is that it’s stretched. The vertex is in the IV quadrant for g(x) rather than at the origin for f(x).

I hope that helps.

lbvjy [14]

Answer: his weekly allowance is $8

The model to solve the problem is

X/2+8=12

Tom is buying topsoil for the flower bed shown below. One bag of topsoil covers 15 square meters. How many bags of topsoil does
____ [38]

Answer:

We need 4 topsoils

Step-by-step explanation:

I think your question is missed of key information that is the area of the flower bed, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.

My answer:

The flower bed is a triangle with its height is 5 cm and the base length is 12 cm, so we need to find out the area of it:

  • S = Height*the base length = 5 * 12 = 60 m^{2}  

So the bags of topsoil does Tom need to cover his flower bed is:

\frac{Area of the flower bed}{The area of the topsoil } = \frac{60}{15} = 4

We need 4 topsoils
