If you would like to find the matching equation, you can do this using the following steps:
ax^2 + bx + c = 0
a = -2
b = 1
c = 3
-2x^2 + x + 3 = 0
The correct result would be a. 0 = <span>-2x^2 + x + 3.</span>
If you would like to know what was the percent decrease in price, you can calculate this using the following steps:
x% of $299.99 is $180.55
x% * 299.99 = 180.55
x/100 * 299.99 = 180.55
x = 180.55 * 100 / 299.99
x = 60.19%
100% - 60.19% = 39.81%
The correct result would be 39.81%.

Answer:
-22
Step-by-step explanation:
6j-5k=11
5j-6k=22
-----------------
5(6j-5k)=5(11)
-6(5j-6k)=-6(22)
-----------------------
30j-25k=55
-30j+36k=-132
-----------------------
11k=-77
k=-77/11
k=-7
6j-5(-7)=11
6j+35=11
6j=11-35
6j=-24
j=-24/6
j=-4
------------------
2j+2k=2(-4)+2(-7)=-8-14=-22
