Suppose y varies inversely with x. Write an equation if y=-3 when x=17
vodka [1.7K]

Answer:

y = -51 ÷ x

Step-by-step explanation:

The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = -3 when x = 17 and y varies inversely with x.

So we substitute the values y = -3 and x = 17 in the equation y = k ÷ x

K = constant, we have to work this out

-3 = k ÷ 17

-3 × 17 = k

k = -3 × 17

k = -51

k = -51 So then we put this back into the original y = k ÷ x to find our final equation which is y = -51 ÷ x

Hey! since it’s a 5 sided shape it’s area will be 540° so you add up 108+100+90+120=418
the final angle is 122*
then since angles on a straight line is 180° you minus 122 from 180 and x= 58°
