Because others would estimate it differently.
Answer:
Check.
Step-by-step explanation:
To prove it we need to know that for two matrices A and B we have that:
det(AB) = det(A)*det(B) and
. Now:





.
You sum the like terms
-6b+3b + 11+2
the answer is -3b+13
<u>Corrected Question</u>
Create a circle with center A and a radius of your choice. Create a point B on the circle, and find the coordinates of B. Draw the radius AB. What is the slope-intercept form (y = mx + b) of the equation of AB? Show your work.
Answer:
y=0.62x+2
Step-by-step explanation:
In the attached circle drawn using Geogebra
- Center is at point A(0,2)
- Point B on the circumference has coordinates (1.7,3.05)
- Radius of the circle=2 Units
Gradient of AB,
where 

Line AB intercepts the y-axis at y=2, therefore: b=2
The slope-intercept form of the line AB (in this case) is therefore:
y=0.62x+2
For every circle center A of radius r and point B chosen on the circumference, the equation of the line AB will be different.

18×7=126
483+126=609
21×7=147
462+147=609
After 7 games each will have 609 points.
