The inverse function of the function y = log₂ 4x is f ⁻¹(x) = 2ˣ/4.
Given the function is :
y = log₂4x
we are asked to find the inverse of the function.
steps to find inverse function are:
Change f(x) to y to get y = ax + b for the provided function f(x) = ax + b.To get x = ay + b from the equation y = ax + b, replace x with y and y with x.Here, find y and solve for x = ay + b. Then we get y = (x - b/a).Finally, we can substitute y = f-1(x) with f-1(x) = (x - b)/a.now interchange the positions of x and y in the function.
x = log₂4y
the next step is to isolate the dependent variables.
f ⁻¹(x) = 2ˣ/4
hence, we get the inverse of the given function as f ⁻¹(x) = 2ˣ/4

Let g(x)=5 x-2 and h(x)=x²+1 . Find the value of each expression. (g ⁰ h)(a)
For the functions g (x) = 5 x - 2 and h (x) = x² + 1, the value of the composite function g o h (a) will be 5 a² + 3.
We are given the functions:
g (x) = 5 x - 2
h (x) = x² + 1
We first need to find the composite function g o h (x).
So, we get that:
g o h (x) = g ( h (x) )
g o h (x) = 5 ( x² + 1 ) - 2
g o h (x) = 5 x ² + 5 - 2
g o h (x) = 5 x² + 3
Now, we need to find the value of the composite function for x = a. So, we get that:
g o h (x = a) = 5 (a)² + 3
g o h (a) = 5 a² + 3
Therefore, for the functions g (x) = 5 x - 2 and h (x) = x² + 1, the value of the composite function g o h (a) will be 5 a² + 3.

a jogger begins her workout by jogging to a park, a distance of 12 miles. she then jogs home at the same speed, but along a different route. this return trip is 18 miles, and her time is one hour longer. find her jogging speed.
The jogging speed of the jogger is 6 miles/hour.
Given that:-
Distance from home to park = 12 miles
Distance from park tp home from a different route = 18 miles
It is also given that the time taken to reach home from park is 1 hour longer than the number of hours taken to reach park from home.
We have to find the speed of the jogger.
Let the time taken by jogger to reach park from home be t hours.
Hence, according to the data given in the question,
Time taken by jogger to reach home from park is (t+2) hours.
We know that,
Speed = distance/time
We know that the speed of jogger in each route is same.
Hence, we can write,
12/t = 18/(t+1)
2/t = 3/(t+1)
2(t+1) = 3t
2t+2 = 3t
t = 2 hours.
Hence, speed of the jogger = 12/2 = 6 = 18/(2+1) = 18/3.

Write a rational function with the given characteristics.
A vertical asymptote at x=-4 and a horizontal asymptote at y=3
The rational function with the given characteristics is [tex]f(x) = \frac{3x + 1}{x - 4} [/tex].
How to find a rational function with the given characteristics?Any function that can be expressed mathematically as a rational fraction—an algebraic fraction in which both the numerator and the denominator are polynomials—is referred to as a rational function. The polynomials' coefficients don't have to be rational numbers,they can be found in any field K.
given that a vertical asymptote at x=-4.
A horizontal asymptote at y=3.
The denominator of the function cancels for this value and the numerator does not cancel at this value if the rational function has a vertical asymptote at x=4.
[tex]f(x) = \frac{p(x)}{(x - 4)} [/tex]
The degree of the numbered variable is equal to the degree of the denominator if the rational function has a horizontal asymptote at y=3, and the coefficient of the higher degree variable is three times larger.
Hence,
[tex]f(x) = \frac{3x + 1}{x - 4} [/tex]

can someone help? Work out the missing numbers in the identity
__ (p²-2) - p(2p³- __) =p(p²-2) + 3 p
Step-by-step explanation:
I hope you wrote the equation correctly.
there could be parts missing. and exponents be wrong.
I am concerned, because the missing parts are not just numbers. they are full terms in the variable p.
so, well, the right side is
p³ - 2p + 3p = p³ + p
on the left side we have
a(p² -2) - p(2p³ - b)
ap² - 2a - 2p⁴ - pb
so, the first thing we see : we need to eliminate the p⁴ terms, because there are none on the right side.
so,
a = 2p²
that gives us
2p⁴ - 4p² - 2p⁴ - pb = -4p² - pb
let's see, if we can create the missing items just by "b" (and we have to get rid of -4p²) when we bring left and right sides together again :
-4p² - pb = p³ + p
p³ + p + 4p² = -pb
b = (p³ + p + 4p²)/-p = -p² - 1 - 4p
so,
the equation would look like
2p²(p² - 2) - p(2p³ - (-p² - 1 - 4p)) = p(p² - 2) + 3p
which could be also written as
2p²(p² - 2) - p(2p³ + p² + 1 + 4p) = p(p² - 2) + 3p
6x+5y=39
3x+5y=27
grade 8
Answer:
y = 3 and x = 4
Step-by-step explanation:
Let's solve your system by substitution.
6x+5y=39;3x+5y=27
Step: Solve6x+5y=39for x:
6x+5y=39
6x+5y+−5y=39+−5y(Add -5y to both sides)
6x=−5y+39
6x/6=−5y+39/6
(Divide both sides by 6)
x=−5/6y+13/2
Step: Substitute −5/6y+13/2 for x in 3x+5y=27:
3x+5y=27
3(−5/6y+13/2)+5y=27
5/2y+39/2=27(Simplify both sides of the equation)
5/2y+39/2+−39/2=27+−39/2
(Add (-39)/2 to both sides)
5/2y=15/2
5/2y/5/2=15/2/5/2
(Divide both sides by 5/2)
y=3
Step: Substitute 3 for y in x=−5/6y+13/2:
x=−5/6y+13/2
x=−5/6(3)+13/2
x=4(Simplify both sides of the equation)

Answer:4.5 hours, 4 hours and 30 minutes, 4 and a half hours
Step-by-step explanation: you are averaging, so you add all of the numbers together and divide that by the number of numbers.
3+6=9, 9 divided by 2=4.5
Answer:
2hours
Step-by-step explanation:
let windows = x
Mrs. Saunders can clean one-third of the windows in an hour = x/3
daughter can clean one-sixth of the windows in an hour = x/6
so,
x/3+x/6 = 1

y = x - 2
y = - 0.5x + 4
Answer:
(4, 2 )
Step-by-step explanation:
y = x - 2 → (1)
y = - 0.5x + 4 → (2)
substitute y = x - 2 into (2)
x - 2 = - 0.5x + 4 ( add 0.5x to both sides )
1.5x - 2 = 4 ( add 2 to both sides )
1.5x = 6 ( divide both sides by 1.5 )
x = 4
substitute x = 4 into (1)
y = 4 - 2 = 2

For each direct variation, find the constant of variation. Then find the value of y when x=-3 .
y=1 when x=-1.5
After direct variation y = 2 when x = -3.
What do we mean when we say "direct variation"?To give the reader a hint, direct variation equations use the same phrase.The phrase could be "directly proportional" or "directly varies."For example, the area of a square is proportional to the square of its side.The variational constant is k = 3 if y varies directly as x and y = 6 when x = 2.As a result, y = 3x is the direct variation equation.So,
The initial statement is y = kx
Then to find y when x = -3.
K constant will be y/x ⇒ 1/-1.5That is y = kx ⇒ y = 1/-1.5 × xWhen x = -3:
1/-1.5 × -3 ⇒ y = 2Therefore, y = 2 when x = -3.

She needs to locate the squares of the integers between 7.1 and 7.2 in order to estimate √51.
What is the square root of a number?Finding an integer's square root is the inverse of squaring an integer. A number's square value is obtained by multiplying it by itself, whereas the square root of a number can be discovered by looking for a number that, when squared, produces the original value. It follows that a× a = b if "a" is the square root of "b." Every number has two square roots, one of a positive value and one of a negative value because the square of any number is always a positive number.
In the question given to us,
look at the table, we know
(7.1)² = 50.41 and (7.2)² = 51.84
So, (7.1) < √51 < 7.2 { estimate }

Substitute the values into m = y2 - y1/x2 - x1:
Slope (m) of the line = (0 - 2) / (-5 - (-4))
Slope (m) of the line = (-2) / (-5 + 4)
