Answer: $f(-735) = -\frac{2}{3}(-735) + 490 = 980$

Step-by-step explanation:

$f(x) = -\frac{2}{3} x + 490 =0$ Subtract 490 from both sides

$\frac{3}{2}* -\frac{2}{3} x = -490 *\frac{3}{2}$ Then flip $-\frac{2}{3}$ multiply both sides by $\frac{3}{2}$ to cancel out $-\frac{2}{3}$

$x= -735$ Thus giving you -735 as your $x$ .

Then you plug it back into the equation to solve.

If y varies inversely as x, and y=1 as x=2 find y for the x- value of -1

Lina20 [59]

Inverse variation is of the form y=k/x (direct variation is of the form y=kx)

We are given that x=2 when y=1 so using the inverse form y=k/x we can solve for the constant of variation...

1=k/2

k=2

so the equation is:

y=2/x now they want us to find y when x=-1 so

y=2/-1

y=-2
