Answer:

Irrational

Step-by-step explanation:

Any non-zero rational number multiplied by an irrational number will be irrational. We can rewrite this as (8.57... * 5) / 8, but we have no idea how to make 8.57... * 5 rational, or expressed as the quotient of two integers.

Solve the system of equations x + y = 0 and x + 9y= -48 by combing the eqatuons

lidiya [134]

Answer:

x = 6

y = -6

Step-by-step explanation:

x + y = 0 (Multiply by -1)

x + 9y= -48

-x - y = 0

x + 9y= -48

8y = -48

y = -6

x + y = 0

x - 6 = 0

x = 6

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>
