3c-d
3c-(-c+7)
3c+c-7
4c-7
Final answer: 4c-7
He should set up the refreshment stand on the incenter of the obtuse triangle. The incenter of a triangle is described as the intersection between the angle bisectors of a triangle. The inradius are the line segments from the incenter of the triangle to each of the three sides of the triangle which are all equal. The inradius is depicted as the radius of an inscribed circle in the triangle. Therefore, the shortest equal distance from his stand to each road is C. on the incenter.
Answer:
not direct variation
Step-by-step explanation:
The equation for x and y in direct variation is
y = kx ← k is the constant of variation
y =
is not in this form, thus not direct variation.
The equation for x and y varying inversely is
y =
← k is the constant of variation
y =
is in this form and represents inverse variation
1. Reflect over x axis, right 1, up 8
2. Ref. over x, stretch 4 (up and down), up 6
3. Stretch 2 (side to side), left 9, down 5
4. stretch 8 ( s to s), reflect over y, down 4
5. Ref. over x, stretch 2/7 (s to s), up 5
