Answer:
Q1. 1050 miles
Q2. 1h 30m
Step-by-step explanation:
Q1. 1h = 300 miles
3
h = 3.5 × 300 miles
= 1050 miles
Q2. 68km = 1h
102km =
× 1h
= 1.5h
= 1h 30m
Answer:
100
Step-by-step explanation:
6×100=600
600 might not be that much close to 3236 but it's not over 3236
Answer:
y= 407.54654 ft
Step-by-step explanation:
This is an exponential decay functions
y = ab^x where a is the initial value and b is ( 1 - rate of decay)
a = 520
b = 1- 3%
y = 520 ( 1- .3) ^x
y = 520 ( .97) ^x
We want x to be 8 weeks
y = 520 ( .97) ^8
y= 407.54654 ft
So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

Next, now that we have the value of y, substitute it into either equation to solve for x:

<u>And this is how you get your final answer (5,2).</u>
