Answer is B
9/4 <x <= 4
...........
Answer:
C
Step-by-step explanation:
Like terms mean same variable. it doesnt really matter if its negative in the front.
Answer:
f(x) = 1
Step-by-step explanation:
f(x) = -x-5
f(-6) = -(-6)-5 = 6-5 = 1
So walked 4/5 mile in a 4/9 h so just use the rule of 3 simple
60 minutes ------ 1 hour
x min. ----------- 4/9 h
--------------------------------
x = 4/9 *60/1 = 240/9 = 26,6 min.
4/5 mile -------in 26,6 min.
1 mile -------- x min.
-----------------------------
x = 1*26,6/(4/5) = 26,6 /(0,8) = 33,25 min.
1 mile ..... 33,25 min.
x miles ----- 60 min.
---------------------------
x = 60/33,25 = 1,8 miles
so their unit rate in miles per hour will be 1,8 miles / hour
hope this will help you
The least common multiple can be found a couple of ways. For this, it is probably easiest to identify the unique factors of each expression.
(6x -18) = 6(x -3) = 2*3*(x -3)
(2x² -6x) = 2x(x -3)
Then the unique factors are 2, 3, x, (x -3). Their product is the LCM:
LCM = 6x(x -3) = 6x² -18x
_____
If one or more of the factors is raised to a power other than 1, use the highest power of that factor in the final product.
