Riley is deciding between two different movie streaming sites to subscribe to Plan A costs $22 per month plus $1 per movie watched. Plan B costs $18 per month plus $2
per movie watched. Let A represent the monthly cost of Plan Aif Riley watches o per
month, and let B represent the monthly cost of Plan B if Riley watches a movies per
month. Graph each function and determine which plan would be cheaper if Riley
plans on watching 6 movies each month.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
