Y = mx + b is <span> the "slope-intercept" form of the equation of a line ;
We have y = -x + 6 ;
Then, m = - 1 ;
</span><span>The "point-slope" form of the equation of a straight line is:
</span><span>y - y1 = m(x - x1) ;
But, x1 = - 3 and y1 = 8 ;
We have y - 8 = (-1)( x + 3 );
Finally, y - 8 = -( x + 3 );
The right answer is the fourth choice;
________________________________________
</span><span>y – 3 = (x – 1) ; the equation becames
</span>
y = x + 2 ;
The right answer is the third choice;
Answer:
The circumference is a irrational number
Step-by-step explanation:
we know that
The circumference of a circle is equal to
where
D is the diameter
In this problem we have that
---> is a rational number
substitute
Remember that
The number π is a irrational number
and
If you multiply a rational number by a irrational number, the result is a irrational number
therefore
The circumference is a irrational number

c = cost
The area of the shaded region is 1486 m².
Step-by-step explanation:
The question requires you to find the area of the shaded part.Find the area of the triangle then subtract the area of the circle to remain with the area of the shaded region.
Area of a triangle = 1/2 *base length*height
Area of a triangle= 1/2*60*60=1800 m²
Area of the circle= πr²
Area of the circle=3.14*10*10=314 m²
Area of the shaded region = 1800-314=1486 m²

Answer:
In mathematics, a percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", or the abbreviations "pct.", "pct"; sometimes the abbreviation "pc" is also used. A percentage is a dimensionless number (pure number).
