Its option B because if she us depositing same amount of money each month then it would just multiply by number of times money is deposited
Answer:
(x + y)(p - q)
Step-by-step explanation:
Given
px + py - qx - qy ( factor the first/second and third/fourth terms )
= p(x + y) - q(x + y) ← factor out (x + y) from each term
= (x + y)(p - q)
Rewritten: 4(5.75 + 4.25)
solved: 4(10) = 40
explanation: it was easier this way because we did not have to work with decimals
Answer: D
Step-by-step explanation:
If the equation is f(x) = 9x^2 -12, you can solve for the inverse by switching the x and y like this.
x = 9y^2-12.
Then you solve for y.
x = 9y^2-12.
x+12=9y^2
y^2=(x+12)/9
y=sqrt((x+12)/9)
y=sqrt((x+12))/3 which is D
This is the concept of statistics. The correct answer is:
There are twice as many participants in the 0-19 age group than in the 60-79 age group. This is because:
Number of participants in the age group 0-19 is 40 participants
Number of participants in the age group 60-79 is 20 participants.
From the above we see that the age group 0-19 is double the number of age group 60-79 years old.
Therefore our answer is option C
