Step-by-step explanation:
3x+2y=22
5x-2y=42
by adding both equation
8x. =64
x=64/8=8
substituting x in the 1st equation
we get,
3*8+2y=22
24+2y=22
2y=22-24
y=-2/2=-1
therefore,
x=8
y=-1
I think A is 145m...
200m+ (-55m) since the submarine is under water it will be negative which ends up to be 145m
Y=-4/5x+1 is the equation for bc
Answer:
10th term means n = 10
we have general term = n² -8
substituting the value of n we get
10² - 8 = 100-8 =92
