Answer:
Discounted price = $495 Discount Rate = 34% Solution: Let x = Original Price x = 495 + 0.35x ;Multiply whole equation by 100 to remove decimals. 100x = 49500 + 35x ;Transpose 35x to the left side of the equation. 100x-35x = 49500 ; Subtract the x terms. 65x = 49500 ; Divide both sides by 65. x = 761.54 So the original price is $761.54.
A points location will change after you add a negative value to the y coordinate even if you leave the x coordinate the name because you are changing the value of the y coordinate. For example, if you have (4,6) as a coordinate and then change it to (4,-6), the coordinate will now just be on the other side of the x axis
There are many ways to do this. Such ways are using the quadratic formula, completing the square, etc.
We have
We can add 46 to both sides so the -21 becomes a +25. by doing that, we get
This can be wrote as
We solve the square root and get
(The +- is a plus minus sign.) Subtract five on both sides to get
The answer is
C.
51.2 ounces.
