Answer:
2
Step-by-step explanation:
Basically I use rise over run, or rise ÷ run.
The rise is 4 and the run is 2 in the section I chose. 4÷2 is equal to 2, so the rate of change is 2 feet per second.
Answer:
x+y=-8
Step-by-step explanation:
y-x=4
x=3y
y-3y=4
x=3y
-2y=4
x=3y
y=4/(-2)
x=3y
y=-2
x=3*(-2)
x=-6, y=-2 then
x+y=-6-2=-8
In step 3, Mark forgot to multiply 5 · 5, so he ended up with 5 in the denominator instead of 5 · 5 = 25
ANSWER
EXPLANATION
The given quadratic equation is:
We rewrite in the standard quadratic equation form to obtain,
Comparing this to the general standard quadratic equation.
We have my
The total time spent in minutes is 110 minutes
<h3>How to determine the total time?</h3>
The given parameters are:
- Erica = 1 hour, 15 minutes
- Sean = 35 minutes
The total time is calculated as:
Total = Erica + Sean
So, we have:
Total = 1 hour, 15 minutes + 35 minutes
1 hour = 60 minutes
So, we have:
Total = 60 minutes + 15 minutes + 35 minutes
Evaluate the sum
Total = 110 minutes
Hence, the total time spent is 110 minutes
