A machine produces 540 parts every 4 of an hour. The person running the machine says that the machine should
produce 720 parts in each 8-hour day. Is the answer reasonable? Why or why not?
O No. The machine will produce 4,320 parts per day, since 540 x 8 = 4,320,
O No. The machine will produce 3,240 parts per day, since 405 * 8 = 3,240.
O No. The machine will produce 720 parts in 1 hour, not in 1 day.
540x3 = 405
O No. The machine will produce 405 parts per day, since
of an hour, and
O Yes. The machine produces 540 parts in

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

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
