First distribute the 3

12y - 15 = 69

Subtract -15 from both sides 

12y = 84

<u>y=7</u>

PROOF:

3 (4 *7 - 5) 

3 (28-5)

3 (23) = 69

Y<span>= 7 because if you divide both sides by three you get 3(4y -5) </span><span> ÷ 3 and 69</span><span> ÷ 3 and you simplify it you get 4y - 5 </span><span>= 23 then add 5 to both sides 4y - 5 + 5 = 23</span> <span>+ 5  simplify that you get 4y </span><span>= 28 divide again but divide both sides by 4
4y </span><span>÷ 4    28 </span><span>÷ 4 simplify one more time and y </span><span><span>= 7!</span> </span>

What is the common ratio between successive terms in the sequence? 2, -4, 8, -16, ​
Marianna [84]

Answer:

the answer is f(x) = n*(-2)

ratio is the wrong word to use, it is for contolled variation in probability. a sequence is controlled by what is known as a function - f(x) is the symbol for a function

Step-by-step explanation:

the following number of the previous one in the sequence is derived by the function f(x)=n*(-2)

2 x -2 = -4 (positive x negative = negative)

-4 × -2 = 8 (negative x negative = positive)

8 x -2 = -16 (positive x negative = negative)

so in the sequence, the trend of -,+ double will go on
