Answer:
y = -3/8x -41/8
Step-by-step explanation:
Perpendicular lines intersect at 90° and their slopes are opposite reciprocals.
Therefore the slope changes from 8/3 to -3/8.
Now we must solve for the new y-intercept (b) by plugging in the given coordinate (-3,-4).
The result is b = -41/8 so our new equation is:
y = -3/8x -41/8
Answer:
Josh sold 16 books and Jessica sold 240 books
Step-by-step explanation:
Given: Jessica sold 15 times more books than Josh.
Together they sold 256 books
To Find : How many did each one of them sell?
Solution:
Let Jessica sold x books
Let Josh sold y books.
Since we are given that Jessica sold 15 times more books than Josh.
⇒x=15y --a
We are also given that Together they sold 256 books.
⇒x+y=256 --b
Using substitution method
Put value of x from equation a in equation b
⇒15y+y=256
⇒16y=256
⇒
⇒
Thus Josh sold 16 books
Jessica sold books = 15y = 15*16=240
Hence Josh sold 16 books and Jessica sold 240 books
