Answer:
The land area of Florida is 
Step-by-step explanation:
Let
x -----> the land area of Alaska in square miles
y -----> the land area of Florida in square miles
we know that
The linear equation that represent this problem is equal to
----> equation A
----> equation B
substitute equation B in equation A and solve for y
Remember that
Florida's land area is one-tenth the size of Alaska is the same as to say that Alaska's land area is ten times the size of Florida
Solve x(x-5)=0; the roots are 0 and 5.
Draw a number line. Plot 0 and 5 on this line.
Set up 3 intervals, as follows: (-infinity, 0), (0, 5), and (5, infinity).
Now choose a test number from within each interval (e. g., -2, 3, 10).
Subst. each into the inequality x(x-5)
0. In each case, determine whether the inequality is true or false.
Based upon your results here, you should be able to determine on which interval or intervals the inequality is true. Those interval(s) is/are your solution set.
Answer:
x = 9
Step-by-step explanation:
given f(x) = 3x and f(x) = 27, then equating f(x) gives
3x = 27 ( divide both sides by 3 )
x = 9
