If y varies inversely as x and } = 3 when x = 4, then y

Andrews [41]

Answer:

FALSE

Step-by-step explanation:

If y varies inversely as x., this is expressed as;

y = k/x

k is the proportionality constant

when y = 3 and x = 4

3 = k/4

k = 3 * 4

k = 12

when x = 15;

y = k/x

y =12/15

y = 4/5

Hence y is not equal to 12 when x = 15.

The correct answer is FALSE

valentinak56 [21]

Answer:

The equation that represents the graph is y = 40x

The new equation would be y = 45x

Step-by-step explanation:

As y increases by 40, x increases by 1, so 40/1, or 40

New equation: $90 per 2 months, y = 90, x = 2, 90/2 = 45
