Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
- 6x - 4y = 2 → (1)
- 4x - 7y = 2 → (2)
Multiplying (1) by 4 and (2) by - 6 will eliminate the x- term
- 24x - 16y = 8 → (3)
24x + 42y = - 12 → (4)
Add (3) and (4) term by term
26y = - 4 ( divide both sides by 26 )
y = 
= - 
Answer:
8x+7y^2

Answer:
Kristi
Step-by-step explanation:
The formula for Simple Interest =
Principal × Rate × Time
For Kristi
Kristi invests $3,000 at a 7.25% annual simple interest rate,
Principal = $3000
Rate = 7.25% = 0.0725
Time = 1
Simple interest = $3000 × 0.0725 × 1
= $217.5
For Kari
Her sister Kari invests $3,200 at a 6.25% annual simple interest rate.
Principal = $3200
Rate = 6.25% = 0.0625
Time = 1
Simple interest = $3200 × 0.0625 × 1
= $200
From the above calculation, we can see that: Kristi will earn the greater amount of interest after one year
