it is the 3(4) because it is addenig not multiplying
The correct answer for this completion exercise shown above is
the second option (Option B), which is: B. Parent
Therefore, you have:"In each family of function, the parent function is the most basic function in the family"
By definition, the
most basic fucntion in each family of functions is called “parent fucntion”. A
family of function is a set of function that when you graph them, you can notice
that they have common charateristics.
Let x represent the number of grandstand seats on race track #2
The number of grandstand seats on race track #1 = 37,000 + 3x
Total number of seats together = 289,000
So, we can frame the equation as follows:
37,000 + 3x + x = 289,000
4x + 37,000 = 289,000
4x = 289,000-37,000 = 252,000
4x = 252,000
x = 252,000/4
x = 63,000
Number of seats on race track #2= x = 63,000 seats
Number of seats on race track #1 = 37000+3x = 37000+3*63000 = 226,000 seats
Answer:
42
Step-by-step explanation:
L=2W+5
LW=42
(2W+5)W=42
2W^2+5W-42=0
(2W-7)(W+6)=0
2W-7=0
2W=7
W=3.5 ANS.
L=2*3.5+5=7+5=12 ANS.
PROOF:
3.5*12=42
42=42
