What are the transformations for the graph of y = (x + 4)10 - 2?
the answer to this question can be solved by setting up a proportion, or equivalent ratios (fractions). since we know that 18 questions was equal to 72% correct on the test, we can set up a proportion to find the total number of questions:
, where 'x' represents the total number of questions (or 100%) of the questions on the test.
cross-multiply and divide: 72x = 18(100) or 72x = 1800
divide both sides by 72: 72x/72 = 1800/72
solve for x: x = 25 questions
to convert a mixed number of the form a b/c for an improper fraction, you will get (ac+b)/c. use this on the two fractions to get 4/3 to 5/3. "to" is just another word for "divided by" or "over". so, we can do 4/3 divided by 5/3, and if you multiply both numbers by 3, it will not change the result, because you are multiplying by 3/3 or 1, so you will get your final answer is 4/5.
the correct answer to this is 18 in²
formula of the area of triangles: ½ × b × h = a
in this case it is: ½ × 4 in × 9 in = a = 36 × ½ = 18 in²
