a) Parallel and goes through (-4,1).

b) Perpendicular and goes through (-4,1).

15.Given 5x+2y=7

a. Find an equation parallel to the equation and through (0,10).

b. Find an equation perpendicular to the equation and through (0,10).

This picture is an example of what the answers should look like.

what is the answer?

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

pls mark as brainliest.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

b. b < 1 might be the correct answer
