Answer:
A. ![y=-\dfrac{8}{7}x-\dfrac{18}{7}](https://tex.z-dn.net/?f=y%3D-%5Cdfrac%7B8%7D%7B7%7Dx-%5Cdfrac%7B18%7D%7B7%7D)
Step-by-step explanation:
Let
be the equation of the perpendicular line.
Two perpendicular lines have slopes with product equal to -1. The slope of the given line is
Hence,
![\dfrac{7}{8}\cdot m=-1\\ \\m=-\dfrac{8}{7}](https://tex.z-dn.net/?f=%5Cdfrac%7B7%7D%7B8%7D%5Ccdot%20m%3D-1%5C%5C%20%5C%5Cm%3D-%5Cdfrac%7B8%7D%7B7%7D)
is the slope of needed line.
This line passes through the point (-4,2), so its coordinates satisfy the equation:
![2=-\dfrac{8}{7}\cdot (-4)+b\\ \\b=2-\dfrac{32}{7}=-\dfrac{18}{7}](https://tex.z-dn.net/?f=2%3D-%5Cdfrac%7B8%7D%7B7%7D%5Ccdot%20%28-4%29%2Bb%5C%5C%20%5C%5Cb%3D2-%5Cdfrac%7B32%7D%7B7%7D%3D-%5Cdfrac%7B18%7D%7B7%7D)
Therefore, the equation of the line is
![y=-\dfrac{8}{7}x-\dfrac{18}{7}](https://tex.z-dn.net/?f=y%3D-%5Cdfrac%7B8%7D%7B7%7Dx-%5Cdfrac%7B18%7D%7B7%7D)
Answer:
2 cakes with the sugar she has and there will still be some sugar left.
Step-by-step explanation:
Amount of sugar in the cabinet of Cassie = 1/2 pound
Amount of sugar required by Cassie to make her cake recipe = 2/10 pound
= 1/5 pounds
Then
The number of cakes that Cassie can make = (1/2)/(1/5)
= 5/2
= 2 1/2
