Suppose that x and y vary inversely, and x = 7 and y=11. Which function models the inverse variation?Answers:Y=1.57xY=77/xY=4/xY
sdas [7]

Answer:

Y=77/x

Explanation:

Y varies inversely with x meaning

y\propto\frac{1}{x}

adding a proportionality constant gives

y\propto\frac{k}{x}

Now, we are told that y = 11 and x = 7; therefore, the above gives

11=\frac{k}{7}

Solving for k gives

k=77

Therefore, the function that models the inverse variation is

y=\frac{77}{x}

which is our answer!

Solve for m.<br> m/9 + 2/3 =7/3
Nuetrik [128]

Answer:

m= 15

Step-by-step explanation:

\frac{m}{9}  +  \frac{2}{3}  =  \frac{7}{3}

To solve for m, start by moving the constants (numbers that are not attached to any variable) to the other side of the equation.

\frac{m}{9}  =  \frac{7}{3}  -  \frac{2}{3}

Simplify:

\frac{m}{9}  =  \frac{5}{3}

Multiply both sides by 9:

m =  \frac{5}{3}   \times 9

Crossing out 3 from the denominator and from 9:

m= 5(3)

m= 15
