The possible values of x are given by x+8=&lt;6.<br><br>The greatest possible value of 7x is_____​
kozerog [31]

Answer:

The possible values of x is given by x\leq  -2 and they include: -2, -3, -4, -5, -6 and so on

The greatest possible value of 7x is -14

Step-by-step explanation:

We are given the equation: x + 8 <= 6

Let collect the like terms:

x + 8 \leq  6\\x\leq  6 -8\\x \leq  -2

Therefore, x <= -2 and the possible values include: -2, -3, -4, -5, -6 and so on

To find the greatest possible value of 7x is when x = -2.

7x = 7 * -2\\7x = -14\\.

If f(x) = 6x − 5 and f(5a) = 73, then what is the value of a?
Dmitrij [34]

Answer:

a =13/5

Step-by-step explanation:

f(x) = 6x − 5

f(5a) = 6*5a − 5=73

       30a -5 = 73

Add 5 to each side

    30a -5+5 = 73+5

      30a =78

Divide  by 30

30a/30 = 78/30

a =13/5
