2. One light flashes every 2 minutes and another flashes every 7 minutes. If both lights flash at 1 p. m., what is the first time after 3 p. m. the same day that both lights
will flash together?

it is 32.5

i hope i could u.

umm you say your want to . but you do know that this is the mathematics.  

o~o

so mark-up is 0.4 multiplied by 180 = 72

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
