Answer:
a
Step-by-step explanation:
the solution to the system is at the point of intersection of the linear equations.
the lines intersect at (- 4, 3 )
then solution is (- 4, 3 )
I think it’s 1/2 divided by 2
Answer: A' (-4,0)
Step-by-step explanation:
the ratio of the length and width = 3:2
Step-by-step explanation:
let the length be =x
width be = 
area of a rectangle = length X width
so, x X
= 384
or,
X 2/3 = 384
or,
= (384 X 3)/2
= 576
or, x = 24 ( taking square root)
hence, length is 24
width is = 24 X (2/3)
=16
so the ratio of length and width = 24 : 16
= 3:2
3x + 2y = 19
x + y = 8
3 (x + y) = 3 (8)
3x + 3y = 24
3x + 2y = 19
-
3x + 3y = 24
--------------------
-y = -5
y= 5
x + y = 8
x + 5 = 8
x = 3
(3, 5)
