So I always go to this site for grade calculations
https:// rogerhub. com /final-grade-calculator/
So go down to "I already took my final" or something like that
So with you having a 99, then got a 45% on a project that's worth 50% of your grade, your grade unfortunately drops 72%.
The correct answers for x would be
.
In order to find this, we must first get the equation to equal 0. In order to do that, subtract 1 from each side to get the following.
11
- 4x - 1 = 0
Knowing this we can now use the quadratic equation using a = 11, b = -4 and c = -1. The quadratic equation is below.
Now we can plug the values into the equation to solve.
Then simplify using the order of operations.

Answer:
-49/3 and -25/3
Step-by-step explanation:
Let the numbers be represented by f and s (first and second). Then f = s - 8. Also, 2f = 3s + 9. Solve this system for f and s:
Substituting s - 8 for f in the 2nd equation, above, yields
2(s - 8) = 3s + 9, or 2s - 16 = 3s + 9. Then 3s = -25, and s = -25/3. The first number is then f = s - 8, or f = -25/3 - 8, or f = -49/3.
