Tell whether the lines for each pair of equations are parallel, perpendicular, or neither
y= -3x + 7 -2x+6y=3

Perpendicular lines

Step-by-step explanation:

We are given that

We have to find the pair of equations are parallel , perpendicular or neither.

Differentiate each equation w.r.t.x

Using rule :

When two lines are perpendicular then ,

When two lines are parallel then, slope of two lines are equal.

We have

Hence, the lines are perpendicular.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

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
