Step-by-step explanation:
then find your y and x and plot it
Answer:
125/10 which can be simplified to 25/2.
Step-by-step explanation:
The factors of an expression are the quotients of the expression
The model that represents the factors of
is the product of x -1 and x - 8
<h3>How to determine the model</h3>
The expression is given as:
![x^2 - 9x + 8](https://tex.z-dn.net/?f=x%5E2%20-%209x%20%2B%208)
Expand the expression
![x^2 - 8x - x + 8](https://tex.z-dn.net/?f=x%5E2%20-%208x%20-%20x%20%2B%208)
Factorize the expression
![x(x - 8) - 1(x - 8)](https://tex.z-dn.net/?f=x%28x%20-%208%29%20-%201%28x%20-%208%29)
Factor out x - 8
![(x - 1)(x - 8)](https://tex.z-dn.net/?f=%28x%20-%201%29%28x%20-%208%29)
Hence, the model that represents the factors of
is the product of x -1 and x - 8

Answer:
- m∠1=m∠4=m∠5=m∠8=67°;
- m∠2=m∠3=m∠6=m∠7=113°.
Step-by-step explanation:
Consider two parallel lines a and b with transversal m. These lines form 8 angles.
Note that
Since the difference of two angles is 46°, then these angles should be, for example, ∠1 and ∠2. These angles are supplementary, then
m∠1+m∠2=180°.
Solve the system of two equations:
![\left\{\begin{array}{l}m\angle 1+m\angle 2=180^{\circ}\\m\angle 2-m\angle 1=46^{\circ}\end{array}\right.\Rightarrow \left\{\begin{array}{l}2m\angle 2=226^{\circ}\\2m\angle 1=134^{\circ}\end{array}\right.\Rightarrow \left\{\begin{array}{l}m\angle 2=113^{\circ}\\m\angle 1=67^{\circ}\end{array}\right..](https://tex.z-dn.net/?f=%5Cleft%5C%7B%5Cbegin%7Barray%7D%7Bl%7Dm%5Cangle%201%2Bm%5Cangle%202%3D180%5E%7B%5Ccirc%7D%5C%5Cm%5Cangle%202-m%5Cangle%201%3D46%5E%7B%5Ccirc%7D%5Cend%7Barray%7D%5Cright.%5CRightarrow%20%5Cleft%5C%7B%5Cbegin%7Barray%7D%7Bl%7D2m%5Cangle%202%3D226%5E%7B%5Ccirc%7D%5C%5C2m%5Cangle%201%3D134%5E%7B%5Ccirc%7D%5Cend%7Barray%7D%5Cright.%5CRightarrow%20%5Cleft%5C%7B%5Cbegin%7Barray%7D%7Bl%7Dm%5Cangle%202%3D113%5E%7B%5Ccirc%7D%5C%5Cm%5Cangle%201%3D67%5E%7B%5Ccirc%7D%5Cend%7Barray%7D%5Cright..)
Then
- m∠1=m∠4=m∠5=m∠8=67°;
- m∠2=m∠3=m∠6=m∠7=113°.
