Both the original and the inverse are functions because for each value of C there is a unique value of F and vice-versa.

Answer:
12 1/2 dollars
Step-by-step explanation:
add 10 9/10 and 6 3/5
you have least common multiple of the demoninators which is 10
so 6 3/5 is equal to 6 6/10
the you can add which gets you 16 15/10
simplified is 17 5/10 then you can change it to 17 1/2
then you subtract that from 30
30-17 1/2 = 12 1/2 dollars
Answer:
$0.68
Step-by-step explanation:
Convert the percentage to a decimal.
6.8% = 0.068
Multiply the amount by the decimal to find the tax.
9.95 × 0.068 = 0.6766
The tax is $0.68.
Answer:
l = 2, m = - 1, n = - 6
Step-by-step explanation:
A scalar matrix has its diagonal elements equal and all other elements zero, so
2l - 4 = 0 ( add 4 to both sides )
2l = 4 ( divide both sides by 2 )
l = 2
---------------------------------------
3l + n = 0
3(2) + n = 0
6 + n = 0 ( subtract 6 from both sides )
n = - 6
--------------------------------------
3m - n = 3
3m - (- 6) = 3
3m + 6 = 3 ( subtract 6 from both sides )
3m = - 3 ( divide both sides by m )
m = - 1
