Answer:
x = -3 ; y = -6
Step-by-step explanation:
x = y + 3
-2x + 4y = -18
-2(y+3) + 4y = -18
-2y -6 + 4y = -18
2y = -12
y = -6
x = -6+3
x = -3

Answer:
$6200
Step-by-step explanation:
Given data
Rate= 4%
Principal=$5000
Time = 6 years
The simple interest formula is
A=P(1+rt)
substitute
A=5000(1+0.04*6)
A= 5000(1+0.24)
A=5000*1.24
A=$6200
surface area is the area of all the faces on a shape so to speak.
2(120 x 110)=26,400
2(120 x 4)=960
2(110 x 4)=880
880+960+26,400=28,240
Surface area = 28,240
I would try using Photomath or Desmos both great graphing apps!
