<h3>How to find the solution to a system of equations?</h3>
Any system of equations can be solved in different methods. To solve a system of equations in 2 variables, we need at least 2 equations following all the steps given below.
From equation 1
Substitute the value of y in equation 2
Substitute x = 0 in the equation 1
Hence, the solution of the equation is x = 0 and y = 8.

Earthquake measuring 4.5 is 10 times more powerful than earthquake measuring 3.5 on Richter scale.
Step-by-step explanation:
Earthquake refers to the violent shaking of the Earth crust in response to its extremely dynamic interior. Sometimes the rocks are loaded or stressed beyond its elastic limit, following which it rebounds thus emitting a wave(seismic), which is received by us as seismic waves.
The energy released during an earthquake is measured in Richter scales (named after Charles Richter). While 1 is the lower limit, there is no such upper limit. However, earthquakes above 7 are considered fragile for human existence. It is a logarithmic scale meaning successive numbers of the scale by a factor of 10.
Thus, an earthquake measuring 4.5 would be around 10 times more powerful than an earthquake measuring 3.5 following logarithmic scale.
Answer:
eigenvalues depends on the characteristic polynomial equation formed A-lambda I
Step-by-step explanation:
Consider that while calculating A--lambda I 2nd order characteristic polynomial is formed , where the characteristic polynomial always has two roots.
SO these are eigen values.
Which can be real imaginary or complex .
In 3X3 the eigen values will be 3.
Answer:
First, we need to find the rate.
210 = 21x
x = 10
We need to know how much he gets in 35 hours
35x
35(10) = 350
D is your answer.
Using the given information, the unit rate is 0.0645 miles/minute
<h3>Calculating rate </h3>
From the question, we are to determine the unit rate
From the given information,
Daniel runs 40/5 miles in 124 minutes
That is,
Distance = 40/5 miles = 8 miles
Time = 124 minutes
Using the formula,
Rate = Distance / Time
Rate = 8 miles / 124 minutes
Rate = 0.0645 miles/minute
Hence, the unit rate is 0.0645 miles/minute
