The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
Answer:
y</= 2
Step-by-step explanation:
9 + 1 = 10
9 + 2 < 10
y = anything < 2
Step-by-step explanation:
can't really use the Pythagorean because you don't know this is a right triangle.
use the fact that they are similar
so
3/6 = x/12 where x is FE
cross multiply
6x = 36 therefore FE = 6
then 6/12 = y/9 where y is FD
cross multiply
12y = 54 = 54/12 therefore FD = 4.5
I set it up as an equation. 1/4x = 1/7x + 3. After you solve it out, it’s 28.
