For questions #1-4 tell whether x and y show direct variation, inverse variation or neither and explain how you know. Equation Variation and explanation 1) = 5 2) 2xy 13 3) 3x + y = - 2 4) xy 2 / 7​

it would be 6xy and -16xy.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
