Answer:

B. Decreasing

Step-by-step explanation:

We have been given formula of a function F(x)=9\cdot (\frac{1}{7})^x. We are supposed to determine the type of our given function.

We know that an exponential function is in form y=a\cdot b^x, where,

a = Initial value,

b = If b>1, then the function is growth function. If b, then the function is decay function.

Upon looking at our given function we can see it is in form of exponential function.

Upon comparing our given function with standard exponential function, we can see that the value of a is 9 and value of b is \frac{1}{7}.

Since \frac{1}{7}, therefore, our function is decreasing and option B is the correct choice.

Whats the lcd of 1/7,14/17,12/13,5/6
gizmo_the_mogwai [7]
LCD (1/7, 14/7, 12/13, 5/6)

LCM = (7, 7, 13, 6)

=  2 * 3 * 7 * 13

=  546



1/7  = 78/546

14/7  = 1092/546

12/13  = 504/546

5/6  = 455/546




Calculation:

1/7 + 14/7 

= 1 + 14/7

=  15/7


The common denominator you can calculate as the least common multiple of the both denominators:   LCM (7, 7) = 7


Add:

15/7 + 12/13 

= 15 . 13/7. 13  + 12 . 7/13 . 7

= 195/91 + 84/91

=  195 + 84/91 

=  279/91


The common denominator you can calculate as the least common multiple of the both denominators:  LCM (7, 13) = 91



Add:

279/91 + 5/6

= 279 . 6/91 . 6 + 5 . 91/6. 91

= 1674/546 + 455/546

= 1674 + 455/546 

= 2129/546



The common denominator you can calculate as the least common multiple of the both denominators:  LCM (91, 6) = 546



Hence, 546 is the LCM/LCD of (1/7, 14/17, 13/13, 5/6).






Hope that helps!!!!!!

1. -222=-2x-3(4x+18)<br>2. 154=2x-6(-2x-14)<br>solve for x​
Aleksandr [31]

Answer:

1. x = 12

2. x = 5

Step-by-step explanation:

1. -222 = -2x - 12x - 54

-222 = -14x - 54

-168 = -14x

x = 12

2. 154 = 2x + 12x + 84

154 = 14x + 84

70 = 14x

x = 5
