For this case we have the following system of equations:
5x + 3y = 17
-8x - 3y = 9
We can rewrite the system like:
Ax = b
Where,
A = [5 3; -8 -3]
b = [17; 9]
x = [x; y]
The determinant of matrix A is given by:
lAl = ((5) * (- 3)) - ((3) * (- 8))
lAl = (-15) - (-24)
lAl = -15 + 24
lAl = 9
Answer:
The determinant for solving this linear system is:
lAl = 9
jack is 284 and lacy is 71 cuz 71 x 4 is 284
plz mark brainlyest
Bye!
I think its 222064 i'm pretty sure it's correct
<span>40=2x+12+2x
4x=28
x=7
x+6=13
ans:
length of the window=7 ft
width of the window=13 ft</span>
Yes there is! It’s actually called a 30-60-90 triangle lol (these people with their obvious mam inch crack me up). There are special side length rules which is why they are important, I can elaborate if you would like :)
