Which points are on the graph of f(x) = ? check all that apply. (–27, –3) (–1, 1) (0, 0) (1, 1) (3, 27)a

it would be:

c.parallelogram.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

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.

2/3=10/15

1/5=3/15

10+3=13/15

2 13/15 is the answer
