Y = (x/7) - 4; this would be the equation, assuming x is the number.

What’s the inverse equation?
algol [13]

Answer:

The inverse is ((5-x)/4) ^ 1/3

Step-by-step explanation:

y = 5-4x^3

Exchange x and y

x = 5-4y^3

Subtract 5 from each side

x-5 =5-5-4y^3

x-5 = -4y^3

Divide each side by -4

(x-5)/ -4 = y^3

Take the cube root

((x-5)/ -4) ^ 1/3 = y^ 3 ^1/3

((5-x)/4) ^ 1/3 = y

The inverse is ((5-x)/4) ^ 1/3

Step 1: calculate the cube roots, convert the decimal into a fraction, and calculate the cube roots again

10 + 3 square root 27/1000 - 5

Step 2: calculate the cube root

10 + 3/10 -5

Step 3: subtract the #’s

5 + 3/10

Step 4: calculate and you get

53/10


Answer: 53/10

Given a polynomial function f(x) = 2x2 – 3x + 5 and an exponential function g(x) = 2% – 5, what key features do f(x) and g(x) ha
prohojiy [21]

A. Both f(x) and g(x) have the <em>same</em> domain of (9, +\infty).

<h3>How to analyze similarities in two functions</h3>

In this question we must analyze the domain, range, x-intercepts and <em>increase</em> intervals:

<h3>Domain</h3>

Dom \{f(x)\} = \mathbb{R}

Dom \{g(x)\} = \mathbb{R}

Both functions are <em>continuous</em>.

<h3>Range</h3>

Ran \left\{f(x)\right\} = (3.875, +\infty)

Ran \{g(x)\} = (-5, +\infty)

<h3>x-Intercepts</h3>

f(x): (x,y) = \emptyset

g(x): (x,y) = (2.322, 0)

<h3>Increase intervals</h3>

f(x): According to the graph, f(x) increase over the interval of (3.875, + \infty).

g(x) : According to the graph, g(x) increase over the interval of \mathbb{R}

After a quick analysis, we conclude that option A offer the best approximation to characteristics of both functions. \blacksquare

<h3>Remark</h3>

The statement presents mistakes and is poorly formatted. Correct form is:

<em>Given a polynomial function </em>f(x) = 2\cdot x^{2}-3\cdot x + 5<em> and an exponential function </em>g(x) = 2^{x}-5<em>. What key features do </em>f(x)<em> and </em>g(x)<em> have in common? </em>

<em />

<em>A.</em><em> Both </em>f(x)<em> and </em>g(x)<em> have the same domain of </em>(9, +\infty)<em>.</em>

<em>B.</em><em> Both </em>f(x)<em> and </em>g(x)<em> have the same range of </em>(-\infty, 0]<em>.</em>

<em>C.</em><em> Both </em>f(x)<em> and </em>g(x)<em> have the same x-intercept of </em>(2,0)<em>.</em>

<em>D.</em><em> Both </em>f(x)<em> and </em>g(x)<em> increase over the interval of </em>(-4, +\infty)<em>.</em>

In how many ways can Susan arrange 10 books into 3 slots on her bookshelf?
ahrayia [7]
Hello there,

If she has 10 books and she can arrange it 3 ways on her bookshelf, you just multiply 10 and 3

10 x 3= 30

Susan can arrange 10 books into 3 slots 30 ways.

Hope this helps!
