F(x)= 2x+1/3x-4 H(x)=3x³-7EvaluateF(x)–¹And Fh(4)

Answers

$f(x) = (2x + 1)/(3x - 4)$
h(x) = 3x³ - 7

$f(x) = (2x + 1)/(3x - 4)$
$y = (2x + 1)/(3x - 4)$
$y(3x - 4) = (3x - 4)((2x + 1)/(3x - 4))$
$y(3x) - y(4) = 2x + 1$
$3xy - 4y = 2x + 1$
$3xy - 2x = 4y + 1$
$x(3y) - x(2) = 4y + 1$
$x(3y - 2) = 4y + 1$
$(x(3y - 2))/(3y - 2) = (4y + 1)/(3y - 2)$
$x = (4y + 1)/(3y - 2)$
$y = (4x + 1)/(3x - 2)$
$f^(-1)(x) = (4x + 1)/(3x - 2)$

f(h(4)) = 3x³ - 7
f(h(4)) = 3(4)³ - 7
f(h(4)) = 3(64) - 7
f(h(4)) = 192 - 7
f(h(4)) = 185

$f^(-1)(x) - f(h(4)) =(4x + 1)/(3x - 2) - 185$
$f^(-1)(x) - f(h(4)) =(4x + 1)/(3x - 2) = (185(3x - 2))/(3x - 2)$
$f^(1)(x) - f(h(4)) =(4x + 1)/(3x - 2) = (555x - 370)/(3x - 2)$
$f^(-1)(x) - f(h(4)) =((4x + 1) - (555x - 370))/(3x - 2)$
$\f^(-1)(x) - f(h(4)) =((4x - 555x) + (1 - 370))/(3x - 2)$
$f^(-1)(x) - f(h(4)) =(-551x - 369)/(3x - 2)$

To determine the appropriate landing speed of an airplane, the formula D = .1x 2 − 3x + 22 is used, where x is the initial landing speed in feet per second and D is the distance needed in feet. If the landing speed is too fast, the pilot may run out of runway; if the speed is too slow, the plane may stall. What is the appropriate landing speed if the runway is 800 feet long?

Day and Night Kennel charges $20 per day plus a food fee of $15 to board a pet. Home Away From Home Kennel charges $30 per day plus a food fee of $5. Which system represents this real-world situation?

Answers

Let,

"p" represent the total cost to board the pet (food fee + charge per day included)
"d" represent the total number of days to board the pet

Now,
$$$The equation to find how much Day and Night Kennel chargers :$
$$$ p\ =\ 20d+15$

$$$The equation to find how much Home Away From Home Kennel :$

Which equation shows the quadratic formula used correctly to solve 7x2 = 9 + x for x?

Answers

For future reference, use a * to show the multiplication sign because in math x is a variable. 7*2 = 9 + x

Now multiply 7*2= 14

14 = 9 + x

Now subtract 9 from both sides to isolate the x

5 = x or x= 5

8.92*10^9 in standard notation

Answers

8,920,000,000

Basically just add 9 0's to that number, using the first few to get rid of the decimal places.

. Consider the following standards.MAFS.912.F-BF.1.1b: Combine standard function types using arithmetic operation. For example, build a function that models the temperature of a cooling body by adding a constant function to a decaying exponential, and relate these functions to the model. MAFS.912.F-BF.1.1c: Compose functions. For example, if T(y) is the temperature in the atmosphere as a function of height, and h(t) is the height of a weather balloon as a function of time, then T(h(t)) is the temperature at the location of the weather balloon as a function of time.
Part A: Describe the difference in combining functions and composing functions.
Part B: Give a real-world example of combining functions.
Part C: Give a real-world example of composing functions.

Answers

Part A:

A combined function is defined by combining with existing functions using addition, subtraction, multiplication or division.

A composite function is created by plugging one function into another.
