Naily [24]

Answer:

The sum of the digits of a three digit number is 19. The second digit is one more than the first digit. The third
Oxana [17]

Answer:

  • D. 568

Step-by-step explanation:

Let the number is in the form of xyz

<h3>We have</h3>

Sum of the digits is 19

  • x + y + z = 19

The second digit is one more than the first digit

  • y = x + 1

The third digit is two more than the second digit

  • z = y + 2 = x + 1 + 2 = x + 3

<u>Substitute the values of y and z</u> into the first equation and solve for x

  • x + x + 1 + x + 3 = 19
  • 3x + 4 = 19
  • 3x = 15
  • x = 5

<u>Find the value of y and z</u>

  • y = 5 + 1 = 6
  • z = 5 + 3 = 8

The number is 568

So we know when x = 0, y = 3.<br> What does y equal in the equation <br> y=x2 + 3 if x = 1?
const2013 [10]

Answer:This line contains no two such points. Hence the slope is not defined. A y intercept occurs when we make x equal to 0 . Since this is prohibited by the equation x=−3 , there is no y intercept
