If y varies directly with x and

SashulF [63]

So this is direct proportional question
so y=(k)x
sub y=48 and x=6
48=6k
k=8
now you got a constant k
now sub x=3
y=(8)(3)
=24

Which of the followeing represents the solution...<br><br> 4(9+3z)≤12+6z

julia-pushkina [17]

Solving the inequality $4(9+3z)\leq 12+6z$ we get $z\leq -4$

Step-by-step explanation:

We need to solve the inequality $4(9+3z)\leq 12+6z$

Solving:

$4(9+3z)\leq 12+6z$

Multiplying 4 with terms inside the bracket.

$36+12z\leq 12+6z$

Adding -36 on both sides:

$12z\leq 12+6z-36$

Adding -6z on both sides

$12z-6z\leq 12-36$

$6z\leq -24$

Divide both sides by 6

$z\leq -4$

So, solving the inequality $4(9+3z)\leq 12+6z$ we get $z\leq -4$

Match the one-to-one functions with their inverse functions.

Nady [450]

The inverse of a function is obtained by making x the subject of the formular of the function.

Given the function
$f(x)= \frac{x}{8} -7$
the inverse of the function is obtained as follows:
$y= \frac{x}{8} -7 \\ \\ y+7=\frac{x}{8} \\ \\ x=8(y+7) \\ \\ \bold{f^{-1}(x)=8(x+7)}$

Given the function
[tex[f(x)=x+7[/tex]
the inverse of the function is obtained as follows:
$y=x+7 \\ \\ x=y-7 \\ \\ \bold{f^{-1}(x)=x-7}$

Given the function
$f(x)=1- \frac{x}{3}$
the inverse of the function is obtained as follows:
$y=1- \frac{x}{3} \\ \\ -\frac{x}{3} =y-1 \\ \\ x=-3(y-1) \\ \\ \bold{f^{-1}(x)=-3(x-1)}$

Given the function
$f(x)=20-0.25x$
the inverse of the function is obtained as follows:
$y=20-0.25x=20- \frac{1}{4} x \\ \\ \frac{1}{4} x=20-y \\ \\ x=4(20-y) \\ \\ \bold{f^{-1}(x)=4(20-x)}$
