Answer:
40 and a half
Step-by-step explanation:
Divide 486 by 12.
12 goes into 486 40 whole times.
Answer:
The slope of a line parallel to this line is -7/6, and the slope of a line perpendicular to this line is 6/7.
Step-by-step explanation:
7x+6y=8
6y=8-7x
6y=-7x+8
y=-7/6x+8/6
y=-7/6x+4/3
Parallel lines have the exact same slopes, but perpendicular lines have negative reciprocal slopes.
Answer:
Answer choice C
Step-by-step explanation:
By the Pythagorean Theorem, the square of the length of the hypotenuse is equal to the sum of the squares of the legs. You can rearrange this to find one of the legs using the other two sides of the right triangle:

Therefore, the correct answer is choice C. Hope this helps!
Answer:
y=x+8
Step-by-step explanation:
y=x+b
That is the equation with only the slope, however, we can use the point (-4,4) to find the y-intercept
4=-4+b
Add 4 both sides:
8=b
Thus the equation is y=x+8
