Answer:
The 10% off sale will save Melissa <u>$10.49</u>.
Step-by-step explanation:
Given:
The listed price of the camera is $195.99.
The camera is no sale for 10% off and Melissa has a coupon for 5% off the sales tax is 7%.
Now, to find the money Melissa will save of the 10% off sale.
So, to get the price of camera of the 5% off sale:




Now, adding the sales tax:




Thus, the price is $199.22.
Now, to get the price of 10% off sale:



So, adding sales tax:



Hence, the price is $188.73.
Now, to get the money 10% off sale will save Melissa:


Therefore, the 10% off sale will save Melissa $10.49.
So I guess we are solving for x here :)
So here is my work...
a=2x+6xz
Basically I think it would be
a=6xz+2x
WAIT WAIT NO I'M WRONG FORGIVE ME!
It's x=a/2(1+3z)
<h3>Answer:</h3>
none of these has "no solution"
<h3>Explanation:</h3>
A. The solution is (8/3, 3)
B. The second equation is -1/2 times the first, so these describe the same line. The system has an <em>infinite number of solutions</em>.
C. The solution is (-4, -2)
D. The solution is (4, -2)
E. The second equation is 2 times the first, so these describe the same line. The system has an <em>infinite number of solutions</em>.
_____
A system of equations will have "no solution" when it describes parallel lines—lines that do not intersect. In standard form, such equations are recognizable by their different constants. For example,
- 3x -4y = -4
- 3x -4y = 20 . . . . . . 20 is different from -4
have different constants, so the equations describe parallel lines.
We could multiply one of these by -2 and the system would still be "inconsistent"—having no solution.
