Answer:
5
Step-by-step explanation:
Use the distance formula
You can also just subtract: -2-(-7) to get 5 because the y-values are the same
<em>x = 9</em>
<em>y = 0</em>
- Step-by-step explanation:
<em>y = -2x + 18 </em>
<em>4y - x + 9 = 0</em>
<em />
<em>4(-2x + 18) - x + 9 = 0</em>
<em>- 8x + 72 - x + 9 = 0</em>
<em>- 9x + 81 = 0</em>
<em>81 = 9x</em>
<em>x = 81 : 9</em>
<em>x = 9</em>
<em />
<em>y = - 2×9 + 18</em>
<em>y = - 18 + 18</em>
<em>y = 0</em>
False, you want to subtract in order to get rid of the 2x in both equations
The answer is 8
First divide, then square root to get rid of the squared.
