Answer:

x = -4.8

Step-by-step explanation:

combine like terms

3x + 2x + 6 = -18

5x + 6 = -18

isolate the terms with the x variable

5x + 6 - 6 = -18 - 6

5x = -24

isolate x

5x/5 = -24/5

x = -4.8

Marta walked at 3.3 miles per hour for 0.54 hours. how far did she walk?
Anon25 [30]

This is a proportion, she is walking 3.3 every hour. She walked for 5.4 hours. And we don't know how far she walked so its x/.54. Then you cross multiply which gives you 3.9×.54=x. We multiply those decimals and we get 1.782.

If the exponential parent function,
laila [671]

Answer: f(x) =3^{-x}-4

Step-by-step explanation:

Some transformations for a function f(x) are shown below:

If f(x)+k, the function is translated up "k" units.

If f(x)-k, the function is translated down "k" units.

If -f(x), the function is reflected across the x-axis.

If f(-x), the function is reflected across the y-axis.

Therefore, knowing those transformations and given the exponential parent function:

f(x) = 3^x

If it is reflected across the y-axis and the it is  translated down 4 units, we can determine that the resulting function is:

f(x) =3^{-x}-4
