Answer:

Step-by-step explanation:
4x -10y= 40
Let's rewrite this equation in the slope-intercept form (y= mx +c) so that we can obtain it's slope.
10y= 4x -40
Divide both side by 10:

The product of the gradients of perpendicular lines is -1.
⅖(gradient of line)= -1
Gradient of perpendicular line



The radius of the circle would be 12
1/2 * 5 = 2.5.
You would need 2.5 boxes to build 5 birdhouses.
The answer is d as in dog
