Answer: Store B
Step by Step
divide the the normal price of the book by four to get the amount of the book on sale in store B which is $21. To get the answer for Store A divide the normal price of the book by ten then divide the amount you get by 2 and add the two amounts up to get the the amount of the book on sale which is $21.26
Answer:
SOLVE FOR X, Y
x=12
y=−6
Step-by-step explanation:
the parallel linear equation is:
y = (2/5)*x - 3
<h3>

How to find the parallel line?</h3>
Two lines are parallel if the lines have the same slope but different y-intercept.
Here we know the line equation:
y = (2/5)*x + 4
Then a parallel line is of the form:
y = (2/5)*x + c
Where c is different than 4.
We want this line to pass through (5, -1), then:
-1 = (2/5)*5 + c
-1 = 2 + c
-1 - 2 = -3 = c
Then the parallel linear equation is:
y = (2/5)*x - 3

<span>use an expression
s = speed of the slower car
then
(s+20) = speed of the faster car
When they meet is after 400 miles
Write distance equation
slow car d + fast car d = 400 mi
4s + 4(s+20) = 400
8s + 80 = 400
8s = 400 - 80
8s = 320
s = 40 m/H</span>
