2. The sales of Spicheesy Nachos at the local grocery store are currently 3,200 bags per month. Since Twisty Cheespicy Sticks were introduced,

sales of Spicheesy Nachos have been declining by 48 bags per month.

Twisty Cheespicy Sticks currently sells 1,400 bags per month and its sales

are increasing by 62 bags per month.

Part A: Write expressions for f(x) and g(x) that represent each product's

sales.

Part B: What is the solution to the system?

Part C: What does the solution represent?

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
