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\\.

Find f(-2) if f(x) = x + x + 7. f(-2) =
viktelen [127]

Answer:

f(-2) = 3

Step-by-step explanation:

Given that,

f(x) = x + x + 7

We need to find the value of f(-2).

Put x = -2 in the given function.

f(-2) = (-2) + (-2) + 7

= -2-2+7

= -4+7

= 3

Hence, the value of f(-2) is equal to 3.
