Answer:
2(x -1) - 3(4 x² + 7 x +1)
(-16 x² +10 x - 3) + (4 x² -29 x -2) these expressions are equivalent to the polynomial -12 r²- 19 r -5
Step-by-step explanation:
2(x -1) - 3(4 x² + 7 x +1)
= 2 x -2 -12 x² - 21 x - 3
= -12 x² -19 x -5
This expression is equivalent to the polynomial -12 r² - 19 r -5
Another equation is
(-16 x² +10 x - 3) + (4 x² -29 x -2)
= -16 x² +10 x - 3 + 4 x² - 29 x - 2
= -12 x² -19 x - 5
This expression is also equivalent to the polynomial -12 r² - 19 r -5

Answer:
c. $3,174
Step-by-step explanation:
Using a financial calculator, enter the following inputs to find the Present value (PV) ;
Future value; FV = 4,200
Total duration ; N = 2,920 <em>(365 days in a year times 8 years; 8 * 365 = 2920)</em>
Daily interest rate; I = 3.5% /365 = 0.009589%
PMT = 0
then CPT PV = 3,174.338
Therefore, Arya should deposit $3,174

There are two ways to solve system of equations.
1) substitution method
2) elimination method
4x - y = -6
x - 2y = -5
For thus problem, i'll be using the substitute method.
So, using the equation x - 2y = -5:
Solve for "x" by adding 2y to both sides of the equation.
x = 2y - 5
Now we know what "x" is, we can substitute it in the other equation.
4x - y = -6
4(2y - 5) - y = -6
8y - 20 - y = -6
7y - 20 = -6
7y = 14
y = 2
We now know the numerical value of y. So, all we have to do is plug in y into either system of equation to solve for the numerical value of x.
4x - 2 = -6 x - 2y = -5
4x = -4 x - 2(2) = -5
x = -1 x - 4 = -5
x = -1
The solution is (-1, 2) where x equals -1 and y equals 2.
