Answer:
D. $17.28
Step-by-step explanation:
Multiply the price of gas per gallon by the number of gallons purchased to get your answer
2.469 x 7 = 17.28
By using the given information about the inverse relation, we will get:
- Equation: y = -28/x
- Solution: y = -14
<h3>
How to get the relation between x and y?</h3>
First, we know that y varies indirectly with x, then we can write the relation as:
y = k/x.
Where k is a constant.
Then, we know that when y = 7, we have x = -4.
Replacing these we can find the value of k:
7 = k/(-4)
7*(-4) = k = -28
Then the relation between x and y is:
y = -28/x.
Now, we want to find the value of y when x = 2, then we just replace that in the above equation:
y = -28/2 = -14
So we have:
- Equation: y = -28/x
- Solution: y = -14

<h3>The length of rectangle is 12x³ metres .</h3>
As we know that
♦ Area of rectangle = Length × breadth
Substituting known values ,
⇒ 144x⁴ = 12x ( Length )
⇒ 144x⁴ / 12x = Length
⇒ 12x³ = Length
⇒ Length = 12 x³
Answer:
b. interest rate per period
Step-by-step explanation:
We know that
Annual interest rate is APR or (r)
Po is initial amount
n is number of periods
t is time in years
A is the amount after t years
so,
i is the interest rate per period
Hence ,
answer is
i is the interest rate per period
