The solution to given system of equations is (x, y) = (2, -1)
<em><u>Solution:</u></em>
Given system of equations are:
-1x + 2y = -4 -------- eqn 1
4x + 3y = 5 ------- eqn 2
We can solve the above system of equations by elimination method
<em><u>Multiply eqn 1 by 4</u></em>
4(-1x + 2y = -4)
-4x + 8y = -16 ------ eqn 3
<em><u>Add eqn 2 and eqn 3</u></em>
4x + 3y = 5
-4x + 8y = -16
( + ) --------------------
0x + 11y = -16 + 5
11y = -11
y = -1
<em><u>Substitute y = -1 in eqn 1</u></em>
-1x + 2(-1) = -4
-x -2 = -4
-x = -4 + 2
-x = -2
x = 2
<em><u>Check the answer:</u></em>
Substitute x = 2 and y = -1 in eqn 2
4x + 3y = 5
4(2) + 3(-1) = 5
8 - 3 = 5
5 = 5
Thus the obtained answer is correct
Thus the solution to given system of equations is (x, y) = (2, -1)

Asociative property of multiplication
Answer:
$297.41
Step-by-step explanation:
Given that:
Amount = 9270
Derferred period = 6 months = 0.5 yr
Rate = 17.95% = 0.1795
Amount = 9270(1 + 0.1795)^0.5
Amount = 9270(1.1795)^0.5
Amount = 10067.663
PV = 10067.663
Number of months, n = 48
Monthly amount to be paid :
rp = rate per period = 0.1795/12 = 0.0149583
(rp * PV) / 1 - (1 + rp)^-n
(0.0149583 * 10067.663) / 1 - (1 + 0.0149583)^-48
150.5951234529 / 0.5096723
= 295.47441
Closest option is $297.41
