87.2 - 25.9 = 87.2 - 26 = 61.2 + 0.1 = 61.3
Slope, found using the points is -55/11 = -5
We use that for the equation y=mx+b where m=-5. Since we also know one of the points, we can plug that in and find b
-12=-5(4)+b
-12=-20+b
8=b
So the equation of the line is y=-5x+8
He saved 5/24 of his money
Make common denominators
1/6 * 4/4 =4/24
5/8 * 3/3= 15/24
15/24 + 4/24 = 19/24
24/24 - 19/24
= 5/24
Answer:
we know that
the equation of the circle is of the form
(x-h)^2+(y-k)^2=r^2
where
(h,k) is the center of the circle
r is the radius of the circle
in this problem we have
(x+5)^2+(y-k)^2=r^2
so
the center is the point (-5,3)
the radius is 4 units
therefore
the answer is
The radius of the circle is equal to 4 units
2/6 is a fraction. the denominator has to be an even number.
