18x5=90
Answer:
the lcm of the three factors will be one digit of the number
Step-by-step explanation:
Answer:
$19.10
Step-by-step explanation:
So since he charges $1.85 for the first quarter mile we can keep that as it is for now. If we add 0.25 4 times to make it $1 that would be a mile. We just have to add $17.25 plus the original $1.85 fee
The point-slope form:
![y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29%5C%5C%5C%5Cm%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have the points (3, -4) and (5, 1). Substitute:
![m=\dfrac{1-(-4)}{5-3}=\dfrac{5}{2}\\\\y-(-4)=\dfrac{5}{2}(x-3)](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B1-%28-4%29%7D%7B5-3%7D%3D%5Cdfrac%7B5%7D%7B2%7D%5C%5C%5C%5Cy-%28-4%29%3D%5Cdfrac%7B5%7D%7B2%7D%28x-3%29)
The standard form: ![Ax+By=C](https://tex.z-dn.net/?f=Ax%2BBy%3DC)
<em>multiply both sides by 2</em>
<em>use distributive property</em>
<em>subtract 2y from both sides</em>
<em>subtract 15 from both sides</em>
![-7=5x-2y](https://tex.z-dn.net/?f=-7%3D5x-2y)
<h3>Answer: 5x - 2y = -7</h3>
Answer:
-3
