Answer:
Step-by-step explanation:
is an increasing function as when the value of x increases the value of y increases
And when the value of x decreases , the value of y also decreases.
Now if we have (x+a) or (x-a) instead of x, the function shall have a horizontal shift.
So it shall either move left or right but shall not flip.
So
and
are increasing functions.
Only when x becomes -x, that the function shall flip & shall become a decreasing function.
But then it must be - (x-a) or -(x+a) inside.
So
is also increasing
Only
is a decreasing function.
Option D) is the right answer
Answer:
Step-by-step explanation:
This is exponential. Start with time increments of 1. If we have 4^x, then the bacteria population triples every hour (x=0 -> 1, x=1 -> 4, x=2 -> 16, etc). Now, the problem is that is quadruples every two hours. If you substitute one hour for two, the equation becomes 4^(x/2). (Now at 2 hours, it is 4, at 4 hours, it is 16, ect). I am assuming that the population starts at 1, but it doesn't have to. Let's say the starting population at time 0 is P. Then, the population at time x would be P*4^(x/2). You can verify this for any starting population P>=0 and for any time x>=0.
Answer:
There are a total of 32 Green marbles
Step-by-step explanation:
Let R represent the number of red marbles
Let G repersent the number of green marbles
Write down what is given
G+R=47
Write down what G can also be
G=2R+5
Substitute:
2R+5+R=47
Combine like terms (Algebra)
3R+5=47
Subtract 5 from both sides
3R=42
Simplify
R=14
Substitute the value of R in the equation for G
G=2(14)+5
Solve/Algebra
G=28+5
Solve/Algebra
G=32
