Given the parent functions f(x) = log3 (5x − 5) and g(x) = log3 (x − 1), what is f(x) − g(x)?. . a. f(x) − g(x) = log3 (4x − 4).

b.f(x) − g(x) = log3 (4x − 6). c. f(x) − g(x) = log3 5. d. f(x) − g(x) = = log3 1/5.

$f ( x ) = log _{3} ( 5 x - 5 ), g ( x ) =log _{3} ( x - 1 ); \\ f ( x ) - g ( x ) = log _{3}( 5 x - 5 ) - log _{3}( x - 1 ) = \\ log _{3} \frac{5(x-1)}{x-1} = log _{3} 5$
Answer: C ) f ( x ) - g ( x ) = log3 5

miv72 [106K]

Answer:

x<11

Step-by-step explanation:

x−4(|−2|)<3

Simplifies to:

x−8<3

Let's solve your inequality step-by-step.

x−8<3

Step 1: Add 8 to both sides.

x−8+8<3+8

x<11

Pachacha [2.7K]

Dy/dx (2x⁵ y³ - 4y/x)

dy/dx (2y³ x⁵ - 4y/x)

dy/dx ( 2y³ x⁵ ) - dy/dx (4y/x)

= 2y³ 5x⁴ - (-4y × 1/x²)

=

ANSWER ASAP 30 POINTS!

Slav-nsk [51]

So take 13, 8 and 4 and add those together to get the budget she needs for the month.
13+8+4=25
so she needs $25 in all, to find how much more than 16 she needs you take 25 and minus 16 from it.
25-16=19
so she needs $19 more to have a balanced budget.

<h3>How to evaluate the value</h3>

To find 2x of the vale of x, we have to multiply the value of 'x' by 2

1. x = 1/4

$2x = 2 * \frac{1}{4}$ ⇒ $\frac{2}{4}$ ⇒ $\frac{1}{2}$

2. x = 1/3

$2x = 2 * \frac{1}{3}$ ⇒ $\frac{2}{3}$

3. x = 1/2

$2x = 2* \frac{1}{2}$ ⇒ $\frac{2}{2}$ ⇒ $1$

4. x= 1/6

$2x = 2* \frac{1}{6}$ ⇒ $\frac{2}{6}$ ⇒ $\frac{1}{3}$

5. x = 1/ 7

$2x = 2 * \frac{1}{7}$ ⇒ $\frac{2}{7}$

6. x = 1/8

$2x = 2 * \frac{1}{8}$ ⇒ $\frac{2}{8}$ ⇒ $\frac{1}{4}$

7. x = 2/3

$2x = 2 * \frac{2}{3}$ ⇒ $\frac{4}{3}$

8. x = 3/4

$2x = 2 * \frac{3}{4}$ ⇒ $\frac{6}{4}$ ⇒ $\frac{3}{2}$
