The factors of 21 are 1, 3, 7, and 21
I dont think this is right but (2x3)x(2x4)=48 sorry i dont think that was right
Step-by-step explanation:
Equations:
Quantity:: d = n + 3
Value::: 10n + 5d = 615 cents
-------------------------------------------
Modify::
d - n = 3
d + 2n = 123
--------------------------------------------
Subtract and solve for "n"::
3n = 120
n = 40 (# of nickels)
d = n+3 = 43 (# of dimes)
The index of the root 3 is an odd number, then x can be either positive or negative, then
Domain of the function = R = (-Infinitive, Infinitive)
R. All real numbers
Answer: First option -Infinitive < x < Infinitive
