Independent variable (IV): something the scientist can change.
Thus, in this case, the IV can be the weight of the person.
1) (f + g)(2) = 7 + 3 = 10 The answer is C
2) (f - g)(4) = 11 - 15 = -4 The answer is A
3) f(1) = 2(1) + 3 = 5 g(1) = 1² - 1 = 0 The answer is D
4) (f xg ) (1) = 7/3 The answer is B
The system which models this situation is represented by the answer A.
A.
d = 5 − 15t
d = 18t
Answer:
Step-by-step explanation:
It is a good idea to try to save up money to buy large items or find 0% interest deals so
you are not paying interest. However, this is not always possible, especially when buying
a house or car. That is when it is important to understand how much interest you will be
charged on your loan.
Answer:
r= -d x -t + w
Step-by-step explanation:
d= (w-r)/2 multiply by t to get dt=w-r, the subract w to get dt-w=-r. divide by negative 1 to get -dx-t+w=r (the x means to multiply)
