Bill earns $12 per hour and works at most 40 hours per week. identify the independent and dependent quantity in the situation, and find reasonable domain and range values.

a. amount of money earned; hours worked; 0 to 40; $0 to $480

b. hours worked; amount of money earned; $0 to $480; 0 to 40

c. hours worked; amount of money earned; 0 to 40; $0 to $480

d. amount of money earned; hours worked; $0 to $480; 0 to 40

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

it is true

step-by-step explanation:

all the combinations add up i used   calculator

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
