Answer: The equation of a circle with center (h,k) and radius r is given by (x−h)2+(y−k)2=r2 . For a circle centered at the origin, this becomes the more familiar equation x2+y2=r2
Step-by-step explanation:
Answer: ? = 0.14
Step-by-step explanation:
So you need to find the value that fits the question mark. This means you have to get it by itself.
To start you subtract 0.4 from 0.546, which equals .146. Then you subtract 0.006 from 0.146 to get 0.14
What it looks like mathematically :
0.546 = 0.4 + ? + 0.006
0.146= ? + 0.006
0.14=?
Hopes this helps :)
Yes. youre right, but no2 you can kinda make it a little more 3d like their example just saying
Answer:
-1/2
Step-by-step explanation:
Rearranging this equation to slope-intercept form, we see the slope (x-coefficient) is 2:
2x = 7 + y . . . . . add y
y = 2x -7 . . . . . . subtract 7
The slope of the perpendicular line is the opposite of the reciprocal of this:
-1/2 = slope of perpendicular
