NEED ANSWER BY TODAY ( Nov 12, 2020 ) AT 6:30 p. m. ASAP. The world's future society predicts that by the year 2020, airplanes will be able to carry 1400 passengers. Today's biggest jets carry 600 passengers. What will be the percent of the increase of airplane passengers?

P. S. this is a Percent increase/decrease
from: 600
to: 1400

%/100 = differences of to and from/ from ( before the number )
( no negative difference, bigger number subtract smaller number)

133.33% increase

Step-by-step explanation:

This is a percent increase, and to solve for one you need to know the following formula

Plugging it in;

New value = 1400

Old value = 600

1.3333333 as a percent is

133.33%

So you have an increase of 133.33%

a: 1/6, j: 1/4

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
