Let's split these two situations up.
Linda
Linda deposits $1,800 into an account that pays 7.5% interest, compounded.
The equation:
1,800× 1.075^x=y
Let's put in 10 for x.
1.075^10= 2.06103156 × 1,800= 3,709.85681≈ 3,710
Anna
Anna deposits $4,000 into an account that pays 5% interest, compounded.
The equation:
4,000× 1.05^x=y
Let's put in 10 for x.
1.05×10= 1.62889463×4,000= 6515.57852= 6516
A) Linda's account: $3,710
Anna's account: $6,516
The answer may be A if not then try B
Answer:
y=x+1/2z+-1/2
Step-by-step explanation:
Let's solve for y.
2x−2y+z=1
Step 1: Add -2x to both sides.
2x−2y+z+−2x=1+−2x
−2y+z=−2x+1
Step 2: Add -z to both sides.
−2y+z+−z=−2x+1+−z
−2y=−2x−z+1
Step 3: Divide both sides by -2.
-2y/-2 = -2-z+1/-2
y=x +1/2z+-1/2
