(f + g)(x) = f(x) + g(x) therefore (f + g)(4) = f(4) + g(4)
Answer:
40 min
Step-by-step explanation:
find unit rateeee p=problems
8 p= 2 min
8/2=4
so Alison can do 4 math problems per minute
so 160/4= 40 minutes
hope this helps
Answer:
x=12
Step-by-step explanation:
put the x at one side and the numbers ar the other
5/2x-3/4x=14+7
10/4x-3/4x=21
7/4x=21
7x=84
x=12
Answer:
There will be No solution for the equation
. Option B is correct.
Step-by-step explanation:
We need to determine how many solutions the equation
have.
Solving the equation and finding the solutions

Combining like terms, Moving 3x and 12x to left side of equality and changing their signs and moving 4 on right side of equation and changing sign.

Simplifying

Solving the equation we get 0=9 which is false. So, there will be No solution for the equation
. Option B is correct.
A stem and leaf plot (histogram) shows the mode as the longest list of "leaves." It is the easiest to use for finding mode.
A box-and-whisker plot tells you nothing about relative frequencies.
A scatter plot or line graph would require careful re-interpretation to determine the mode. If the amount of data is large and there are many data values with about the same high frequency, these charts may be unhelpful, too.
