While I have a suspicion you asked your question incorrectly, and the following isnt what you intended to recieve. The answer to this would be 0.0130902291.
The question is asking to choose among the expression that represents the perimeter of the picture frame where as a rectangular picture frame has a width of 9cm and length of x cm and base on the fact, I would say that the answer would be 2x times 18. I hope you are satisfied with my answer
Your standard equation is y = mx + b
P should be the output (y) because it is the final bill. B should be represented by 200 because the $200 is an additional, once payed fee. M should be 30 because the amount payed for dinner depends on how many people are served.
p = final bill
b = 200
m = 30
x = number of friends
So, your equation would look like p = 30x + 200
Hope this helps!
2x 4 =- 8
2 x + 4 = 8 2x+4=8 2x+4=8. Subtract 4 from both sides. Simplify 8 − 4 8-4 8−4 to 4. Divide both sides by 2.
X=-1 Should look like a vertical line that Intersects through -1
