Identify the constant of proportionality for each direct variation below.

andriy [413]

Answer:

see explanation

Step-by-step explanation:

The equation of 2 quantities in direct proportion is

y = kx ← k is the constant of proportionality

y = - 4x ← in standard form

with k = - 4

$\frac{y}{x}$ = 2 ( multiply both sides by x )

y = 2x ← in standard form

with k = 2

$\frac{x}{y}$ = 3 ( multiply both sides by y )

x = 3y ( divide both sides by 3 )

$\frac{1}{3}$ x = y ← in standard form

with k = $\frac{1}{3}$

5v + 7f =28.70 if f is 2.85

adell [148]

Hey!

First, let's write the problem.
$5v+7\left(2.85\right)=28.7$
Multiply $7$ with $2.85$ .
$5v+19.95=28.7$
Subtract $19.95$ from both sides.
$5v+19.95-19.95=28.7-19.95$
$5v=8.75$
Divide both sides by $5$ .
$\frac{5v}{5}=\frac{8.75}{5}$
$v=1.75$

Let me know if you have any questions regarding this problem!
Thanks!

artcher [175]

Answer:

Step-by-step explanation:

Hello!

$f(x)=\frac{1}{7} -9=\frac{1-9*7}{7} =-\frac{62}{7} \\=>f^{-1} (x)=-\frac{7}{62}\\$

Good luck!
