MaplePlace Garage is posting five job listings with the online service.
The cost for their services are:
a) How much is each
posting?
b) How much less does Maple
Place pay per posting
compared to the price for one
posting?
c) What is the cost of the five
postings?
d) What is the total savings
for the five postings?
e) Express the total savings as
a percent of the total cost for
the five postings. Round to
whole percent, (like 50%)

f(x) = y

f(-3) = -5

step-by-step explanation:

42

step-by-step explanation:

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
