y = mx + b
The product of slopes of perpendicular lines is -1. The slope of the given line is 2, so the slope of the perpendicular line is -1/2.
y = (-1/2)x + b
Now use the given point to find b and finish from here.
-5 = (-1/2)(2) + b
b = ?
Answer:
The original equation must have been:
Step-by-step explanation:
A quadratic equation is in the form of :
And it is solved in the form of :
and 
Now the given equation is :
We can see that here;
a = 7
b = -5
c = -2
So, the original equation must have been:
The answer would be about 0.111
Answer:
Area= 50.24 squared cm.
Circumference= 25.12 cm.
Step-by-step explanation:
To find the area of a circle- A= 3.14*(4 cm squared). ( The 4 cm is your radius. Half of the diameter.) After you square your radius you get 16cm squared. You then go onto multiply the 16 cm squared by 3.14 to get 50.24 cm squared.
To find the circumference of a circle- C= 2*(3.14)*(4cm). (Again the 4cm is your radius. Half of the diameter.) After you multiply the 2 and 3.14 you get 6.28. You then multiply the 6.28 by 4 cm to get 25.12 cm.
