<u><em>Answer:</em></u>
The slope of the line is 77
<u><em>Explanation:</em></u>
We know the speed is constant and that the mile-marker location over time can be represented by a line. This means that the equation is linear.
<u>The slope can, therefore, be calculated as follows:</u>

where (x₁ , y₁) and (x₂ , y₂) are two points on the line
We are given that the two points (1, 123) and (3, 277) are two points in the line
<u>Substitute with them in the above equation to get the slope as follows:</u>

Answer:

Step-by-step explanation:
The formula for simple interest is

where <em>p</em> is the principal, <em>r </em>is the rate, and <em>t</em> is the time.
The principal, or initial amount is $800 and the time is 5 years The interest rate is 2.5%, but we must convert to a decimal.
Divide by 100 or move the decimal place two spots to the left.
- 2.5/100=0.025 or 2.5 ⇒ 0.25 ⇒ 0.025
Substitute the known values into the formula.


Multiply.

After 5 years, Suzette's account has earned $100.00
Answer:
A. 64
Step-by-step explanation:
The shoes are 80 dollars. We get a 20% discount
Discount = 80*20%
= 80*.20
=16
The sales price = original price less the discount
= 80 -16
= 64
The correct answer is C. t= 8ln(100)
