ABC Bookstore sells one customer 12 used books and 4 new books for $136. Another customer buys 14 used books and 2 new books for $124. How much
is one used book (u), and one new book (n)?
A. u = $7, n = $13
B. u= $14, n = $2
C. u = $12, n = $4
D. t = $13, n = $7

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

10 b/c 5*2 =10

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

answer is 8 r5
