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.

Fruit Garden: $1/5 for 1/3 lb

Mother Nature: $4 for 5 lbs

Country Market: $0.85 per pound

To Find :

Which store offers the lowest unit rate for cantaloupes, in dollars per pound.

Fruit Garden: (1/5)/(1/3) = $0.6 per pound

Mother Nature: 4/5 = $0.8 per pound

Solve |5x+30|=10x ......
Orlov [11]

Answer:

Option A

Step-by-step explanation:

We need to solve out ,

\implies |5x + 30| = 10x

We can write it as ,

\implies 5x + 30 = \pm 10x

On simplyfing further,

\implies 5x + 30 =  10x \quad or \quad 5x +30=-10x

On solving the above equation , we will get ,

\implies \boxed{ x = 6,-2}

Now we know that the value of modulus is never negative so when we will put x is equal to 2 on the RHS we will get -20 which is not possible . Therefore , the extraneous root is -2 .

<u>Option</u><u> </u><u>A </u><u>is </u><u>correct</u><u> </u><u>.</u>

Please Help!!!!!!
jonny [76]

Answer:

Step-by-step explanation:

The distance that you travelled in your hummer between Olympia and Spokane is 319.4 miles.

You fill up your gas tank with 28.68 gallons of premium gasoline that costs $2.89 per gallon. This means that the total cost of premium gasoline that you bought would be

2.89 × 28.68 = $82.8852

your gas mileage in miles per gallon is 319.4/28.68 = 11.14 miles per gallon.

Therefore, if it costs $82.8852 to drive 319.4 miles,

then the cost of just one mile in your hummer would be

82.8852/319.4 = $0.26 per mile.

The '11' before the decimal point is our whole number.

We can write 11 hundredths as 11 over 100.

11/100

So we have:
