Answer:
g(4a) = 8a^2 -20a +3.5
Step-by-step explanation:
Put 4a where x is and simplify.
g(x) = 0.5x^2 -5x +3.5
g(4a) = 0.5(4a)^2 -5(4a) +3.5
= 0.5(16a^2) -20a +3.5
g(4a) = 8a^2 -20a +3.5
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
Hello.
In order to see if the ratios are equal, we have to simplify both of them.
The first ratio is 8:4.
Divide 8 and 4 by 4:
2:1
Now, simplify the second ratio:
16:64
4:16
1:4
Are 2:1 and 1:4 equal? No.
Therefore, 8:4 and 16:64 are not equal ratios.
I hope this helps.
Have a nice day.

If x/y = 2/3, then all we have to do is multiply x/y by 6. Another way to look at this (the same thing) would be to see 6 as 6/1, so 6 is multiplied by x, and y is multiplied by 1.
But, all the same, you multiply 6 by x/y and you get (2·6)/3 = 12/3 = 4
