2 x
----- = ------
3 15
cross multiply
(3)(x) = (15)(2)
3x = 30
x = 30/3
x = 10
so 2/3 = 10/15.......notice how these are equivalent fractions....that is because proportions are nothing but equivalent fractions
Answer:
There would be 2 answers because it is a quadratic equation
x=4 or x=8
B. y=n+20; 25,26,27 because if you plug in 1 into the equation it equals
21. 2+20=22, etc. so to find the next three terms of the equation plug
in 5: y=5+20=25; plug in 6: y=6+20=26; and plug in 7: y=7+20=27
The coordinates that you record is an example of data from the graph I think
Answer:
f(4) = 5
Step-by-step explanation:
functions are represented by f(x), so x should be the value in parenthesis and the y value should be what it equals
