Answer:
Not true
Step-by-step explanation:
x + (2x + 5) = 3(x – 4)+7
Opening bracket on left and side and distributing 3 over (x-4) on right hand side
x+2x+5=3x-3 x 4 + 7
adding like terms
3x+5=3x-12+7
3x+5=3x-5
Hence
5 = -5
Which is not possible , Hence the equation given to us is false.
I believe that the answer is 25
Answer:
D.
Step-by-step explanation:
Statistics has a lot of usage in business.
Using statistics as well as statistical tools helps in the provision of data to be used for business analysis. With available data we can get patterns in a a large database. Statistics can be used for auditing, as in question option b. For option c, statistics can be used for making business forecasts after the careful observation of trends and patterns that are in the data.
Option d does not make use of statistics. It has nothing to do with statistics neither does it have a computational feature.
Therefore, d.) questioning the executive's strategic decision is the answer to this question
Let x = Parent's age now y = son's age now
Then, x-5 = parent's age five years ago
y-5 = son's age five years ago
So, x-5 = 5(y-5)
Simplify to get x - 5y = -20
Parent's age 8 years from now = x+8
Son's age 8 years from now = y+8
So, x+8 = 3(y+8)
Simplifying, we have x - 3y = 16
We have the system of equations: x - 5y = -20
x - 3y = 16
Subtract the equations to obtain -2y = -36
y = 18
x = 70
Parent is 70 years old and the son is 18 years old.
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain: ( − ∞ , ∞ ) , { x | x ∈ R }
Range: ( − ∞ , 16 ] , { y | y ≤ 16 }
