uhm like, what did you see in the internet is the opposite in the reality
<h2>Part 1)</h2>
Let's analyze each part of the function:
FROM x = 0 TO x = 5:
We can find the equation of this line by using The Slope-Intercept Form of the Equation of a Line, that states:
So the y-intercept here is 
and 
, therefore:
FROM x = 0 TO x = 5:
From the previous line, we know that at 
the output is:
So the point 
lies on both lines.
For this new line, the slope is 
So, with the Point-Slope Form of the Equation of a Line we can find the equation of this other line:
So:
The graph is shown below.
<h2>Part 2)</h2>
The graph of the linear function 
is a line with slope 
and 
at 
. From the items, we can assure that the following equations are linear functions:
In conclusion, the other functions are nonlinear and they are:
Step-by-step explanation: When an equation has a squared term in it
such as x² - 2x - 63 = 0, it's called a polynomial equation.
The rule for solving a polynomial equation is
to first set it equal to 0, them factor.
Since this equation is already set equal to 0, we can factor the left side.
To factor x² - 2x - 63, look for factors of -63 that add to -2.
In this case, these factors are -9 and +7.
So we have (x - 9)(x + 7) = 0.
When two terms are multiplying together to equal 0,
either one term or the other must equal 0.
So x - 9 = 0 or x + 7 = 0.
Solving for x in each equation, we get x = 9 or x = -7.
So this equation has two solutions and we write out answer
in set notation which looks like this {9, -7}.
Answer:
1. -4x + 35 = - 1
2. x = 9 hours
Step-by-step explanation:
Starting at 1:00 pm, temperature changes - 4 degrees Fahrenheit per hour.
At 1:00 pm --> 35 degrees
Our equation will be y = -4x + 35
Substitute -1 in for y:
-4x + 35 = - 1 <--- Answer for the first question
-4x = -36
x = 9 hours <--- Answer for the second question
It will take 9 hours to reach -1 degrees Fahrenheit.
Hope this helps!
