Question

Y varies directly with x, and y is 84 when x is 16. which equation represents this situation

Answer 1

${\huge{\mathfrak{\underbrace{\purple{Answer:-}}}}}$

Write the direct variation equation.

y = kx

Substitute the given x and y values, and solve for k .

84 = y . 16

y = 5.25

Answer 2

Answer:

The required answer is $y=5.25 x$

Step-by-step explanation:

The situation equation is a mathematical formula that is expressed exactly as it appears in the question. An equation created to assist you in solving the issue is the solution equation (variable stands alone)

Given: $Y$ is intimately correlated with $x$, and when $x$ is $16$, y is $84$.

To find: which equation represents this situation.

Based on the given conditions, formulate: $y=k x$

Substitute: $84=k \times 16$

Swap the sides: $k \times 16=84$

Subtract the coefficient of the variable from both sides of the equation.: $k=84 \div 16$

Determine the quotient or product.: $k=5.25$

Write the function's equation.: $y=5.25 x$

Therefore, the equation $y=5.25 x$ represents this situation.
