Answer: [B]: " (-6, 9) " .
_______________________________
Explanation:
_______________________________________
Given the following system of equations:
_______________________________________
x + y = 3 ;
y = 9 ;
_________________________________
Substitute "9" for "y" in the first equation; to solve for "x"; we already have our value for "y" ; "y = 9 " ; (given) ;
____________________________
x + 9 = 3 ;
Subtract "9" from EACH side of the equation;
_____________________________________
x + 9 − 9 = 3 − 9 ;
to get:
_____________________________________
x = -6 .
_____________________________________
Check our answer:
x + y = 3
________________
-6 + 9 =? 3 ? Yes!
_____________________
The answer for the system of equations is:
_____________________________________
x = -6, y = 9 ; or, write as: (-6, 9) .
_____________________________________
which is: Answer choice: [B]: " (-6, 9) " .

The exponential function is given by . The initial investment of $50,000 grows at a rate of about 15% annually.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An exponential function is in the form:
y = abˣ
Where a is the initial value and b is the rate of increase per period.
Let I(t) represent Jennifer’s investment account balance after t years, hence:
a = 50000, b = 100% + 15% = 115% = 1.15

Answer:
Infinite solutions
Step-by-step explanation:
y = x + 1 and x = y - 1
→ Substitute first equation into second one
x = ( x + 1 ) - 1
→ Simplify
x = x
