Step-by-step explanation:
Inequality 1
4(3x - 4) < 32
12x - 16 < 32
12x < 32 + 16
12x < 48
x < 48/12
x < 4
Inequality 2
2x + 1 ≤ 8x + 25
2x - 8x ≤ 25 - 1
- 6x ≤ 24
x ≥ 24/-6
x ≥ - 4
- See the graph below
- Interval [-4, 4)
Answer:
The approximate difference in time is 2 years.
Step-by-step explanation:
The equation for Calvin's account is
To solve for c, we first divide both sides by 400. This gives us:
Using logarithms to solve this, we have
Dividing both sides by 12, we get c = 9.9998 or around 10 years.
The equation for Makayla's account is
Dividing both sides by 300, we get
Using logarithms to solve this, we have
Dividing both sides by 4, we get
m = 11.9999 or about 12.
This means Makayla had her money in the account 12-10 = 2 years longer than Calvin.
