where
α
is some constant that defines the proportionality.
Given

Solve this equation.
24 + 0.44x = 19 + 1.69x
Answer:
x = 4
Step-by-step explanation:
24 + 0.44x = 19 + 1.69x
24 + 0.44x - 1.69x = 19
-1.25x = 19 - 24
-1.25x = -5
x = 4
Step-by-step explanation:
24 + 0.44x = 19 + 1.69x
24 - 19 = 1.69x - 0.44x
5 = 1.25x
1.25x = 5
x = 5/1.25
= 4

Answer:
$16.00
Step-by-step explanation:
6 wood chairs are 444 which is 74.00 a piece
8 metal chairs are 720 which is 90.00 a piece
90-74= 16
The metal chairs are $16.00 more
If Abigail is buying new chairs to upgrade her restaurant. A set of 6 wooden chairs costs $444. A set of 8 metal chairs costs $720. Then the metal chairs are $16.00 more
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Abigail is buying new chairs to upgrade her restaurant.
A set of 6 wooden chairs costs $444.
6W=444
W=444/6
W=74
A set of 8 metal chairs costs $720.
8M=720
M=720/8
M=90
Now we need to find how much more do the metal chairs cost per chair.
We need to find the difference
90-74

through: (0,3), slope = -8
Answer:
y = - 8x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 8 and (0, 3) → c = 3
y = - 8x + 3 ← equation of line

the length of a rectangle is 4 feet longer than its width.its area is 32 square feet.what are its dimensions?
Answer: Length=8, Width=4
Step-by-step explanation: I did this by trial and error, but you can also use an equation. The length is x+4, the width is x. Your equation would be x(x+4)=32. That is equal to x^2+4x=32. Solve this by completing the square. X^2+4x+ (4/2)^2=32+ (4/2)^2
X^2+4x+4=36. (X+2)(x+2)=36. X+2=6, x=4.

Functions f, g, and h are defined as follows: f(x) = x +1, g(x) = x^2 +1, and h(x) = x^3 +1.
(a) Find the inverse of function g(x).
(b) Find f(h(-2))
(c) Find g(f(3)
Answer:
a. let the gx be x
g(x) = x^2+1
or, x^2+1=y
or, x^2= y-1
:. x=2 root y-1
inter changing the relation of xand y
:. x=2 root y-1
:. g-1(x)= 2root x-1
