1. Combine all of the like terms so that you can simplify it, if they are not combined already.
2. Drop all of the constants and coefficients, the constant terms are all of the terms that are not attached to the variable.
3. Put the term in decreasing order of their exponents.
4. Find the power o the largest term.
5. Identify the degree of the polynomial.
6. Know that the degree of a constant is zero.
Hope this helps!
Answer:
Step-by-step explanation:
a) The null hypothesis is the hypothesis that is assumed to be true. It is an expression that is the opposite of what the researcher predicts.
The alternative hypothesis is what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected.
From the given situation,
Carpetland salespersons average $8000 per week in sales. This is the null hypothesis.
H0: µ = 8000
Steve hopes that the results of a trial selling period will enable him to conclude that the compensation plan increases the average sales per salesperson. This is the alternative hypothesis.
Ha: µ > 8000
b) A type I error occurs when a true null hypothesis is rejected.
In this situation, a Type I error would occur if it was concluded that the new compensation plan provides a population mean weekly sales greater than 8000 (correct) when in fact it does not.
c) a Type II error would occur if it was concluded that the new compensation plan does not provide a population mean weekly sales greater than 8000 when in fact, it does.
Other than translation, the transformation that is used to create this frieze pattern is; B: Vertical Reflection
<h3>How to Identify the Transformation?</h3>
Now, we see all the Frieze Patterns on top are being transformed using Translation as it is the exact same pattern throughout the top.
Now, for the bottom we see that is is simply a reflection of the one on top and so it is a vertical reflection because it is reflected across the x-axis.
A vertical reflection reflects a graph vertically across the x-axis, while a horizontal reflection reflects a graph horizontally across the y-axis.

Answer:
See answers below
Step-by-step explanation:
Since both trinagles asre similar hence the ratio of the similar sides are equal.
From both triangles;
y + 7 = 3y - 7
y - 3y = -7-7
-2y = -14
y = 14/2
y = 7
FE = 3y - 17
FE = 3(7) - 17
FE = 21 - 17
FE = 4
AB = y'+7
AB = 7 + 7
AB = 14
Similarly
3x+20 = 5x - 80
3x -5x = -80-20
-2x = -100
x = 100/2
x = 50
<A = 3x + 20
<A = 3(50) + 20
<A = 150 + 20
<A = 170degrees
Hence x= 50 and y = 7
