Answer:
The slope is -2
Step-by-step explanation:
The slope of a line is given by
m = (y2-y1)/(x2-x1)
= (8-4)/(0-2)
= 4/-2
= -2
Answer:
w=12 or w=2
Step-by-step explanation:
2w^2-16w=12w-48
2w^2-28w=-48
2w^2-28w+48=0
2(w^2-14w+24)=0
2(w-12)(w-2)=0
(w-12)(w-2)=0
w=12 or w=2
Answer:
A =78.5
Step-by-step explanation:
We need the radius to find the area of a circle
r = d/2 = 10/2 =5
The area of a circle is given by
A = pi r^2
A = 3.14 (5)^2
A =3.14 (25)
A =78.5
