5 less than a number is equivalent to 1 more than three times the number. the number is​
lutik1710 [3]

Answer:

x = -1

Step-by-step explanation:

5 less than a number is equivalent to 1 more than three times the number

number = x

x - 5 = 3x + 1

now im going to get the numbers and variable on different sides

x - 5 + 5 = x

3x + 1 - 3x = 1

x + 3x = 4x

1 - 5 = -4

4x = -4

lastly im going to divide each side by 4

4x / 4 = x

-4 / 4 = -1

x = -1

3x+1 = 5x-9. what is the value of x?
krok68 [10]
X=5.
Explanation:
Take 3x+1=5x-9 and subtract 1 from both sides.
Now you have 3x=5x-10, Subtract 5x from both sides to get -2x= -10
Now divide both sides by -2 and you have x=5 :).

What is the multiplicative rate of change of the function? The table represents an exponential function.
zhannawk [14.2K]

Answer:

  • <u>The multiplicative rate of change of the function is 0.5</u>

Explanation:

The <em>multiplicative rate of change</em> is the ratio between consecutive entries.

Naming r the multiplicative rate of change, if it is constant you get:

  • r = second entry / first entry = third entry / second entry = fourth entry / third entry.

Here:

  • second entry / first entry = 0.125 / 0.25 = 0.5
  • third entry / second entry = 0.0625 / 0.125 = 0.5
  • fourth entry / third entry = 0.03125 / 0.0625 = 0.5

Thus, the multiplicative rate of change is 0.5. It means that you can obtain each entry as the product of the previous entry times 0.5:

  • 0.25 × 0.5 = 0.125
  • 0.125 × 0.5 = 0.0625
  • 0.0625 × 0.5 = 0.03125

In general, exponential functions have constant multiplicative rate of changes.
