Don't you mean 3z^3?
3z^3 - 300z = 0 can be factored: 3z(z^2-100) = 0
Then either z = 0, or z = 10 or z=-10.
First you must write out the question (it may help to read it out loud)
14+x=17
Subtract 14 from both sides
x=17-14
Solve
x=3
Answer:
D.) $12n + $8u = 112 ;u = 4 + n
Step-by-step explanation:
Given that :
Cost per new books (n) = $12
Cost per used book (u) = $8
Total revenue earned = $112
store sold 4 more used books than new books
Hence,
Total revenue should be :
Revenue from new books + Revenue from used book = total revenue
Revenue from new books = $12 * n = $12n
Revenue from used books = $8 * n = $8n
$12n + $8u = 112
Number of books sold :
Number of used books sold = 4 + number of new books sold
u = 4 + n
Answer:
a function can have two domains having the same range but one domain can not have two ranges
Step-by-step explanation:
example:
{(-2,3),(-3,3),(-4,3)}
Each member of the domain is assigned exactly one member of the range.
