The domain is all real numbers. The range is all real numbers.
The only thing that restricts the domain of an equation is when we are dividing by 0 or have a negative under the square root. Since there is no division sign or square root, we no there is no domain restrictions.
Also, since the range is the exact same as the domain (since f(x) is equal to x), we know the range also have no restrictions.
If I’m not mistaken, I believe that it is 4:12
The answer is 30. 6, 10, and 15 all go into 30.
6x5=30
10x3=30
15x2=30
Answer:
T = 75 + 116.9*N
Step-by-step explanation:
We have that the equation for Michael's savings is:
A = 75 + 50.85*N, where N is the number of weeks
And we have that the equation for his wife's savings is:
B = 65.95*N.
So, to find the total amount saved using both plans combined (T), we have to sum A and B:
T = A + B = 75 + 50.85*N + 65.95*N = 75 + 116.9*N
So the equation that relates T to N is:
T = 75 + 116.9*N
