8 0

Answer:

Step-by-step explanation:

Let n represent the number.

2n+3 . . . . "doubled, then increased by 30"

3n -5 . . . . "five less than three times the number"

These two results are equal, so we have ...

2n +3 = 3n -5

8 = n . . . . . . . . . . add 5-2n

Given:

Mamont248 [21]

Option a. 11 is the right answer

Step-by-step explanation:

To find the value of a function on particular input, the value is put in the function in place of variable

Given function is:

$f(x) = \left \{ {{3x-7\ \ \ x>0} \atop {2x+3\ \ \ x$

As we have to find f(6) and x>0 the part of function 3x-7 will be used

so,

$f(6) = 3(6)-7\\= 18-7\\=11$

Hence,

Option a. 11 is the right answer
