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 the equation of the exponential function that passes through the points (- 1, 1/6) and (1, 2/3) and Use the form y = c * a
icang [17]

Answer:

  • y = 1/3*2^x

Step-by-step explanation:

<u>Given function</u>

  • y = c*a^x

The points (-1, 1/6) and (1, 2/3) lie on the graph

<u>Substitute the values of x and y to get the system of equations:</u>

  • 1/6 = c*a^(-1) ⇒ 1/6 = c/a ⇒ a = 6c
  • 2/3 = c*a^1 ⇒ 2/3 = ac

<u>Substitute a and solve for c:</u>

  • 2/3 = 6c*c
  • 1/9 = c²
  • c = √1/9
  • c = 1/3

<u>Find a:</u>

  • a = 6c = 6*1/3 = 2

<u>The equation of the function:</u>

  • y = 1/3*2^x
