For this question, you need to find the price per unit. The unit in this case is a note, so we are looking for the price of each individual note in the package. The way we find this is by taking the price divided by the number of notes So package one would come out to be (9/18) or .50 dollars per note. Package two would come out to be (12/16) or .75 dollars per not. Package three would be (4/10) or .40 dollars per note. Your answer would simply the one with the lowest price per note, and in this case would be package three
Answer:
14.2126704036
Step-by-step explanation:
I=prt
I=1640*0.06*6/12=49.2
A=1640+49.2=1,689.2
Draw out a horizontal line. Place 0 at the center. Then place evenly spaced tick marks on either side of 0. Label the right side of tick marks as 1, 2, 3, ... moving from 0 and going to the right
Label the left side of tick marks -1, -2, -3, ... starting at 0 and moving left
The location -3 on the number line is exactly 3 units away from 0. We start at 0 and move to -3 by moving 3 spots to the left; or we start at -3 and move 3 units to the right to get to 0.
Therefore, the absolute value of -3 is 3
Absolute value on a number line is the distance a number is from 0
The distance is never negative
Question 1:
F(x) and g(x) are like variables, just plug into the equation.
f(x) + g(x) = (x + 6) + (12x - 7)
x+6+12x-7 = 13x-1
Question 2: f(3) + g(-1)
You plug in the x-values into the equation, and then take the answer and add them together.
f(3) = 3+4
g(-1) = 12(-1)-6
f(3) = 7
g(-1) = -18
7 + (-18) = -11
Question 3:
This is similar to question 1, plug in the variables and simplify.
9x - (7x+3)
Remember to distribute the "-"
9x - 7x - 3
2x - 3
