simple interest=PRT÷100 where P is the amount invested and R is the rate of growth and T is the time taken. so simple interest=(30000×5.6%×4)÷100=$6720
Answer:
x=-1 y= -5
Step-by-step explanation:
y = – x – 6
y = x – 4
Substitute into y = -x-6 into the second equation
y =x-4
-x-6 = x-4
Add x to each side
-x-6+x =x-4+x
-6 =2x-4
Add 4 to each side
-6+4 =2x-4+4
-2 = 2x
Divide by 2
-2/2 =2x/2
-1 = x
Now find y
y =-x-6
y = -(-1) -6
y =1-6
y = -5
