Answer:
(14, -2)
Step-by-step explanation:
To solve by using substitution, begin by solving for a variable in the first equation. Let's solve for x:
Now we know what <em>x</em> equals. Let's substitute this into the second equation:
We can then simplify:
Given equation
Combine y terms
Add 2
Divide by -11
So, we now know the value of y = -2.
To find the value of X, we can substitute the value of Y into one of the equations. Let's use the first one:
Substitute for y
Distribute 8
Add 16
So, we now know the value of x = 14.
Therefore, we know a solution to the system of equations is (14, -2).
Answer:
a) MARKUP PERCENT = 200%
b) <u>If the cost price of clothing A = $10</u>
then its retail price = $30
<u> If the cost price of clothing B = $25</u>
then its retail price = $75
Step-by-step explanation:
Let us assume the original price for the clothing = a
Now, boutique triples the price of the items it purchases for resale.
So, the resale value of the item of clothing = 3 times (Original price) = 3 a
So, here: The resale Value = 3 a
a) MARK UP Percentage =
or, the MARKUP PERCENT = 200%
b) Two expressions that represent retail price
<u>If the cost price of clothing A = $10</u>
then its retail price = 200% of 10 + 10 = 20 + 10 = $30
<u>If the cost price of clothing B = $25</u>
then its retail price = 200% of 25 + 25 = 50 + 25 = $75
The slope is 0, the equation is y=50
When the line is horizontal the slope is 0 and when the line is vertical the slope is undefined.
When the line is horizontal the slope is 0 and when the line is vertical the slope is undefined.
