1. find the equation of the line that is parallel to the line y=-3/2x+4 and passes through point (4,0).2. find the equation of the line that is perpendicular to the line y=-1/3x-1 and passes through point (1,5).

1.

The parallel lines have the same a slope.

We have:

Therefore, the searched line has the equation:

We know, the line passes through point (4,0). Substitute the coordinates of the point to the equation of the line:

2.

Let and

The line l is perpendicular to the line k if and only if

We have

The searched line has the equation:

We know, the line passes through point (1,5). Substitute the coordinates of the point to the equation of the line:

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
