Step-by-step explanation:
The function that models Mason's yearly income is 42,500(1 + 0.035)^x.
Mason's income after 5 years would be $48,084.85.
<h3>What would be Mason's income after 5 years?</h3>
The function that models Mason's income is an exponential function that has the form:
p(1 + r)^x
Where:
- r = percentage increase
- x = number of years
- p = present income
42,500(1 + 0.035)^x
Income after 5 years: 42,500(1 + 0.025)^5 = $48,084.85

Since this is multiple choice ...
• check if B is correct:
x = 0, y = 4, z = 1 ⇒ 3x - y + 4z = -4 + 4 = 0 ≠ -10
(it's not)
• check if C is correct:
x = -2, y = 4, z = 0
⇒ 3x - y + 4z = -6 - 4 + 0 = -10
⇒ 3x - y + 4z = 2 + 4 + 0 = 6
⇒ 3x - y + 4z = -4 - 4 + 0 = -8
While this solution does satisfy the system, it can still have infinitely many other solutions that would work.
• check if D is correct:
Eliminate one of the variables from each equation. For instance,
(3x - y + 4z) + (-x + y + 2z) = -10 + 6
2x + 6z = -4
x + 3z = -2
and
(2x - y + z) + (-x + y + 2z) = -8 + 6
x + 3z = -2
but now it's impossible to eliminate one of the variables.
Therefore there are infinitely many solutions to the system [D].
