Answer:

<u><em>X = -1</em></u>

<u><em>Step-by-step explanation:</em></u>

  • <u><em>Add x to both sides.</em></u>
  • <u><em>8x + 1 + x = -8</em></u>
  • <u><em>Combine 8x and x to get 9x.</em></u>
  • <u><em>9x + 1 = -8</em></u>
  • <u><em>Subtract 1 from both sides</em></u>
  • <u><em>9x = -9</em></u>
  • <u><em>Divide both sides by 9 </em></u>
  • <u><em>x = -9/9</em></u>
  • <u><em>x = -1</em></u>

Help Please!! NO LINKS AND NEED EXPLANATION!
ikadub [295]

Answer:

Function 1: None of the Above

Function 2: Quadratic

Function 3: Linear

Step-by-step explanation:

Function 1: It isn't linear because the y-axis doesn't go up or down at a constant rate, it isn't quadratic because it doesn't have a vertex, and it isn't exponential because it doesn't continue going up.

Function 2: It has a vertex-(6,32)

Function 3: The y-axis goes up at a constant rate of 6.

MaRussiya [10]

Answer:

0.75 miles

Step-by-step explanation:

1. 4/3 is equal to 1.5 or 1.50

2. Divide 1.5 into a half.

1 whole is equal to 0.5 or 0.50

3. Divide the 0.50 in 1.50

0.50 divided by 2 is equal to 0.25

4. Add 0.50 + 0.25

0.50 + 0.25 = 0.75
