Answer:
<h3>Part A</h3>
<u>4 CD's cost $30.40, so one CD costs:</u>
- 4p = $30.40
- p = $30.40/4
- p = $7.60
<h3>Part B</h3>
80% of the regular price is $7.60
<u>If the regular price is r, we have:</u>
- 0.8r = $7.60
- r = $7.60/0.8
- r = $9.5
<u>3 CD's at regular price cost:</u>
Since $25 < $28.5, we can't buy 3 more CD's.
<h3>Part C</h3>
For this case we must find the quotient of the following expression:
Applying double C we have the following expression:
Applying distributive property to the terms within the parentheses of the numerator we have:
Thus, the quotient is given by option A
Answer:
Option A
Hi there! The answer is y = -3x - 21
Let's set up the equation of the line step by step! First we need to know that we need to set up an equation in slope-intercept form. We get the following:
y = ax + b.
a represents the slope of the line.
b represents the intercept with the y-axis.
Since our new line is parallel to y = -3x + 1, both lines have the same slope. Therefore the slope of our line, which is represented by a, is -3.
y = -3x + b.
We also know that this line goes through the point (-5, -6) and therefore we can plug in these coordinates into our formula.
-6 = -3 × -5 + b
Simplify
-6 = 15 + b
Subtract 15
-21 = b
Switch sides
b = -21
Hence, y = -3x - 21
~ Hope this helps you!
Answer:
I dont really understand the question because of the format but...
Step-by-step explanation:
if the original price is 43 and u take 15% off thats more than $5 off
if the original price is 43 and you take 35 % off that is $15.05 off
so the better deal would be 35 % off
Answer:
4 units by 12 units
Step-by-step explanation:
one side of the rectangle is x, the other side is 3x.
3x(x)=48
3x²=48
x²=48/3
x²=16
√x²=√16
x=4
substitute 4 into the original dimensions
