The Drama Club is showing a video of their recent play. The first showing begins at 3:45 p. m. The second showing is scheduled at 6:25 p. m. with a (1/2) −hour break between the showings. How long is the video in hours and minutes? The video is _hours and _minutes. Complete the explanation of how you can use a number line to find the answer. You can work backward from the start time of the second showing at 6:25 pm . You count back 1/2 hour, which is minutes, for the break between showings to _:_

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

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

is there supposed to be a diagram or a graph for this one? ?
