Answer:

r=2

Step-by-step explanation:

r + 8 r + 11 = 29

( 1 + 8 ) r + 11 = 29 9 r + 11 = 29

Now we can isolate and solve for r while always keeping the equation balanced: First, subtract 11 from each side of the equation:

9 r + 11 − 11 = 29 − 11

9 r + 0 = 18

9 r = 18

Now we can divide each side of the equation by 9 to get

r : 9 over 9 = 18 under 9

1 r = 2

r = 2

Answer: r = 2

Steps:  

r + 8r + 11 = 29

9r + 11 = 29

9r + 11 - 11 = 29 - 11

9r = 18

r = 2

For the functions f(x) = 6x – 1 and g(x) = 4x2 + x, find (gºf)(x).<br> Provide your answer bolow
emmainna [20.7K]

For this case we have the following functions:

f (x) = 6x-1\\g (x) = 4x ^ 2 + x

We must find (g_ {o} f) (x):

By definition of composition of functions we have to:

(g_ {o} f) (x) = g (f (x))

So:

(g_ {o} f) (x) = 4 (6x-1) ^ 2 + (6x-1) = 4 ((6x) ^ 2-2 (6x) (1) + (1) ^ 2) + 6x -1 = 4 (36x ^ 2-12x + 1) + 6x-1 = 144x ^ 2-48x + 4 + 6x-1 = 144x ^ 2-42x + 3

We have different signs subtracted and the sign of the major is placed.

Finally we have to:

(g_ {o} f) (x) = 144x ^ 2-42x + 3

ANswer:

(g_ {o} f) (x) = 144x ^ 2-42x + 3

Jess used the equation below to determine f, the total cost of flute lessons, where m represents the number of months of lessons
Alexandra [31]

Answer:the total cost of taming 10 flute lessons is 310

Step-by-step explanation:

The equation to determine f, the total cost of flute lessons is expressed as

f = 25m + 60

Where

m represents the number of months of lessons she would take.

Jess decides to take flute lessons for 10 months. Therefore, the total cost of taming 10 flute lessons would be

f = 25 × 10 + 60

f = 250 + 60

f = 310
