Answer:
Polynomial Function: 3.5n + 1
Total Price of the Apples: $32.50
Step-by-step explanation:
The polynomial function is 3.5n + 1:
The 3.5n comes from the $3.50 it costs to buy an apple, and the n comes from the amount of apples bought. The 1 then comes from the tax that is added onto the price.
The total price of the apples:
3.5n + 1 ; n = 3^3 = 9
(3.5 x 9) + 1
31.5 + 1
32.5
$32.50
Answer: B.
Step-by-step explanation:
Let's solve your system by elimination.
4x−2y=8;−2x+2y=6
Add these equations to eliminate y:
4x-2y=8
-2x+2y=6
2x=14
Substitute 7 for x in 4x−2y=8:
(4)(7)−2y=8
−2y+28=8 (Simplify both sides of the equation)
−2y+28+−28=8+−28 (Add -28 to both sides)
−2y=−20
−2y/−2=−20/−2 (Divide both sides by -2)
y=10
Answer:
Step-by-step explanation:
We can divide 3 out of all three given terms:
3(16x - 2 + y/3)
is one possibility. Where are the answer choices that you were given?
Note: 48x-6+3y/3 is an expression in x and y, but is not an equation. Is that what you intended?
Answer:
22 minutes
Step-by-step explanation:
First you take away the original amount away from the remaining amount.
$25 - $22.36 = $2.64
Then you take that number and divide it by the cents per minute.
$2.64 ÷ 12 = 0.22
Then that's your answer!
Her call lasted 22 minutes.
