Answer:

a graph similar to that of the exponential function but below the "X" axis. Just like a mirror image of"e^x" and intercept the "y" axis when " X=4"

Effectus [21]

(X+4)(X-4) is the LCD because you just have to look at the denominators and see what factors or values are not already part of your LCD.

Which expressions are equivalent to the one below? Check all that apply. 21^x/3^x

satela [25.4K]

Answer:

<em>options: A,C,E </em>are correct.

Step-by-step explanation:

We have to find the expression equivalent to the expression:

$\dfrac{21^x}{3^x}$

we know that: $21^x=(3\times7)^x\\\\21^x=3^x\times7^x$

Hence,

$\dfrac{21^x}{3^x}=\dfrac{3^x\times7^x}{3^x}=7^x$ -----(1)

A) $(\dfrac{21}{3})^x= 7^x$ (same as(1))

Hence, option A is correct.

B) 7 ; which is a different expression from (1)

Option B is incorrect.

C) $7^x$ (Same as (1))

Option C is correct.

D) $(21-3)^x=18^x$ which is a different expression from (1)

Hence, option D is incorrect.

E) $\dfrac{7^x\times3^x}{3^x}=7^x$ ; which is same as (1)

Hence, Option E is correct.

F) $3^x$ ; which is not same as expression (1)

Hence, option F is incorrect.

Answer:

65 parlings

Step-by-step explanation:

<u>Use ratios:</u>

7.5 mots / 37.5 parlings = 13 mots / x parlings
x = 13*37.5/7.5
x = 65

Stephen factored x2−10x 21 and found the answer to be (x 7)(x 3). Is he correct? Question 4 options: yes no.

STALIN [3.7K]

The true statement is that Stephen's factored expression is incorrect.

Given

The expression is given as:

$\rm x^2-10x+21$

<h3>What is factorization?</h3>

Factorization involves splitting a function into factors.

Start by expanding the equation

$\rm x^2-10x+21=0\\\\x^2-7x-3x+21=0$

Factorize the equation

$\rm x^2-7x-3x+21=0\\\\x(x-7)-3(x-7)=0$

Factor out x - 7

$\rm x(x-7)-3(x-7)=0\\\\(x-7)(x-3)=0$

Hence, the true statement is that Stephen's factored expression is incorrect.
