Answer:
9 and 3
Step-by-step explanation:
Let the first number be x and second number be y hence their sum
x+y=12 ......(1)
Making x the subject theb x=12-y
Three times be first number is 3x
3x-y=24.......(2)
Adding the two sets of equations then
4x=36
X=36/4=9
The second number will be 12-9=3
So the first number is 9 and second is 3
-3x+7
Step-by-step explanation:
The entire function f is being multiplied by -1, -1 isn't being plugged in for x in this case.
f -1(x)= -1(3x-7)
f -1(x)= -3x+7
Exponential model 0.996. Yes, 0.996 is very close to 1
A possible domain could be (0,1,2,3...)
If n is the number (not the value) of quarters received, then n cannot take values which are fractions and n cannot take negative values. Its values have to be non-negative integers. (Note that 0 is possible.)
<span>That eliminates the descriptions in answers a, b, and c, leaving only answer </span>
<span>d ( 0,1,2,3,...) </span>
<span>as a possibility. Since it describes the non-negative integers, it's the correct one.</span>
