Answer:
I guess u want to know the quadratic function and its formula is, AX*2 + BX + C. Otherwhise you want to know how to get 0 and get the Xm if you want to know how to solve a quadratic. That formula is, (-B +/- 
(B*2 - 4AC) ) . 1/2 (where A, B and C are the number at the original function).
Step-by-step explanation:
The ratio would be 3:4, or however you write ratios.

We will say the smaller number is X and the larger number is Y
The first sentence states y=x+3 and the second sentence states 4y=6x-13
You can use substitution in this to plug in y=x+3 into 4y=6x-13 to get
4(x+3)=6x-13 now move -13 to the other side to get 4x+16=6x then move 4x to the other side to get 16=2x giving you X
X=8
Now plug in X into the equation y=x+3
y=(8)+3 giving you Y
Y=11
Now plug in both X and Y to check
4(11)=6(8)-13
44=35
Answer: E. 40
Step-by-step explanation:
<u>Concept: </u>
- When you encounter questions that state "what percent of [a] is [b]" then it means asking for a fraction of b to a, which is "(b/a)×100%".
- If you are still confused, I would provide some examples
- What percent of 20 is 5: (5/20)×100% = 25%
- What percent of 10 is 2: (2/10)×100% = 20%
---------------------------------------------------------------------------
<u>Solve:</u>
(16/40)×100% = 0.4 × 100% = 40%
Hope this helps!! :)
