Answer:
There were 14 cartons of size 2 rackets and 24 cartons of size 3 rackets
Step-by-step explanation:
Assume that the number of cartons holding 2 rackets is x and the number of cartons holding 3 rackets is y
∵ There are x cartons of 2 rackets
∵ There are y cartons of 3 rackets
∵ They used 38 cartons
∴ x + y = 38 ⇒ (1)
∵ They packed a total of 100 rackets
∴ 2x + 3y = 100 ⇒ (2)
Let us solve the system of equations
→ Multiply equation (1) by -2 to make the coefficients of x in
the equations equal in values and different is signs
∵ -2(x) + -2(y) = -2(38)
∴ -2x - 2y = -76 ⇒ (3)
→ Add equations (2) and (3)
∴ y = 24
→ Substitute the value of y in equation (1) or (2) to find x
∵ x + 24 = 38
→ Subtract 24 from both sides
∴ x + 24 - 24 = 38 - 24
∴ x = 14
There were 14 cartons of size 2 rackets and 24 cartons of size 3 rackets
Answer:
d) none of the above
Step-by-step explanation:
correct me if wrong .
The answer is 37/6 or by decimal form 6.16
The inverse of this function is y = 
In order to find the inverse of any function, you must start by switching the y and x terms. After doing so, you can then solve for your new y. The result will be the inverse function. The work for this one is done below for you.
y = 3x + 2----> switch the x and y
x = 3y + 2 ----> subtract 2
x - 2 = 3y ----> divide by 3
= y ----> switch the order for consistency
y =
This is now your inverse function.
You need to be more specific: Is that 18% over 5 years or is it 18% per year for 5 years?
If over 5 years, then the value after 5 years would be (1.00-0.18)($19,200), or
$15,744.
