Answer:
-40
Step-by-step explanation:
Plug in 9 for x.
Use Order of operations
-10(9) = -90
-90 + 50 is the same thing as saying 50 - 90
we can simplify by splitting the -90 in to a -40 and a -50
the new equation could be 50 - 50 -40.
50 - 50 = 0
0-40 = -40
Answer:
Step-by-step explanation:
<em>Set 1:</em> 12, 8, 6, 4, 10,1
Now find mean of 6 and 4:
(6+4)/2=10/2:
5 << answer of set 1
<em>Set 2: </em>6,3,5, 11, 2, 9,5,0
(11+2)/2=6.5
<em>Set 3: </em>30, 16, 49, 25
(16+49)=65/2
32.5

Answer:
42
Step-by-step explanation:
I'm pretty sure that this is the answer.
Step-by-step explanation:
Using the Intermediate Value Theorem, the following is applied:
"If f(x) is a continuous on interval [a,b] and we have two points f(a) and f(b) then there must be some value c such that f(a)<f(c)<f(b).
So here there must be a c such that
Note: F(c)=0, the questions that the function have a solution between 0 and 1, so that means we must have some value, c such that f(c)=0 that exists
Next, plug in the x values into the function
Since cubic functions are continuous and -4<0<4, then there is a solution c that lies between f(0) and f(1)
Answer:
1/7 + r = 1/3
Step-by-step explanation:
Rocco takes 7 hours to do the job.
In 1 hour, Rocco does 1/7 of the job.
Rocco's rate is 1/7 job per hour.
It takes Giulia x hours to do the job.
In 1 hour, Giulia does 1/x of the job.
Let r = 1/x. Giulia's rate is r part of the job per hour.
Together, Rocco and Giulia take 3 hours to do the job.
In 1 hour, Rocco and Giulia do 1/3 of the job.
Together, their rate is 1/3 of the job per hour.
1/7 + r = 1/3
