<u>Answer:</u>
D) 6x^2 - 8y^2 = 50
-6x^2 - 2y^2 = 11
<u>Step-by-step explanation:</u>
We are given the following two expressions:
and
Now if we look at the option D) 
and 
, we can observe that the earlier part in the given expression is just a simplification of 6x^2 - 8y^2 = 50.
and the later part is already the same.
Therefore, the correct answer option is D) 6x^2 - 8y^2 = 50
-6x^2 - 2y^2 = 11.
Answer:
Step-by-step explanation:
When you solve these two equations, you end up with the same answer of 1/16 or 0.0625
Answer:
75.2
Step-by-step explanation:
multiple 8 by 9.4
A - 2x^2 + 2x - 2
To find this, set up the equation:
(-x^2 + 6x - 1) + ( 3x^2 - 4x - 1)
With this, you need to combine like terms while taking into consideration the addition sign.
-x^2 + 3x^2 = 2x^2
6x + - 4x = 2x
- 1 + - 1 = - 2
