---------   =     ---------  solved in n=27

7+n                 2

step-by-step explanation:

First, let the number we are looking for be represented by  n .

"three times a number" can then be written as  3 n .

3 n  "added to 4" can this be written as  4 + 3 n

"the number plus 7" can be written as  n + 7

The table shows the outputs, y, for different inputs, x:
ASHA 777 [7]
Part A:
Yes, the data represent a function because there is at least one x-value for every y-value.

Part B:
When x=6 in the input-output table, y=14. When x=6 in the relation f(x)=7x-15, f(x)=7(6)-15=27. <span>The equation has a greater value when x=6.

Part C:</span>
Set f(x) equal to 6 in the equation:
6=7x-15
Solve for x:
7x=21
x=3
<span>x=3 when f(x)=6</span>

Elena L [17]

Answer:

B. a (n) = -3n + 13

Step-by-step explanation:

Given arithmetic sequence is: 10, 7, 4, 1, -2, ...

Here a = 10, d = 7 - 10 = - 3

a_n = a + (n - 1)d \\  \\ a_n = 10+ (n - 1)( - 3) \\  \\  a_n = 10 - 3n  + 3 \\  \\  \purple{ \bold{a_n =   - 3n  +1 3 }}\\  \\
