a is the initial value
r is the rate of change
we have
substitute
Find the amount Amy has at the end of 8 years
For x=8 years
substitute the value of x
Find the Greatest Common Factor (GCF):
GCF = 6
Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF):
6(42/6 + 24n/6)
Simplify each term in parentheses:
6(7 + 4n)
DONE !!
Answer:
The correct answer would be D) 4.8x + 1.2 = 3.6; x = 0.5 mile
Step-by-step explanation:
This is because laps would be the dependent variable, so we know the number of them (4.8) would be multiplied by the variable (x). We also know that 1.2 is the constant. Now we can solve to make sure this is the right equation.
4.8x + 1.2 = 3.6
4.8x = 2.4
x = 0.5
Your answer would be 36.8. All you need to do is add up all of the sides with a calculator.
