Complete question :
A bookstore manager marks down the price of older hardcover books, which originally sell for b dollars, by 52%.
a. Write the markdown as a decimal. b. Write an expression for the sale price of the hardcover book.
Answer:
0.52 ; 0.52b
Step-by-step explanation:
The markdown percentage = 52%
Expresaing markdown as a decimal :
52% = 52 / 100 = 0.52
Expression for the sale price of hardcover book:
Original price = b
Price was marked down by 0.52
Hence, sales price becomes ;
Original price * markdown
b * 0.52
0.52b
That would be a right angle
Answer: -12
Step-by-step explanation: To solve this problem, we can first start by rewriting the problem. When we add a negative, that's exactly the same thing as subtracting so we can make the problem easier to understand.
18 + (-30) → 18 - 30
To find the answer to this problem, let's first find out how many jumps it get's to 0 from 18. It would take 18 jumps and there is 12 jumps left over. Then, we would subtract 12 from 0 and we would get -12 as our answer. Therefore, 18 + (-30) = -12.
2/3 * 6= 4 Or .66 * 6 = 3.999 etc Rounded Is 4
Answer:
y+4 = -1/6(x-9) point slope
y = -1/6x -2.5 slope intercept
Step-by-step explanation:
The point slope form is
y-y1 = m(x-x1)
where m is the slope and (x1,y1) is the point
y- -4 = -1/6(x-9)
y+4 = -1/6(x-9)
Distribute to get to slope intercept form
y+4 = -1/6x +9/6
y+4 = -1/6x +3/2
Subtract 4 from each side
y+4-4 = -1/6x +3/2 -4
y = -1/6x +3/2 -8/2
y = -1/6x -5/2
y = -1/6x -2.5
