Answer:
(- 4, - 10 )
Step-by-step explanation:
Given the 2 equations
y = x - 6 → (1)
x = - 4 → (2)
Substitute x = - 4 into (1) for corresponding value of y
y = - 4 - 6 = - 10
Solution is (- 4, - 10 )
Answer:
Step-by-step explanation:
From the problem statement, we can setup the following equation:

where
is the number of months that Rachel has saved up money.
Dividing both sides by 35, we get the answer:

This would be an exponential function.
Exponential functions are of the form
y = a*bˣ, where a is the initial value, b is the rate the function changes by, and x is the time period. Since this triples, b would be 3.
