Answer:
It's the first one
Step-by-step explanation:
If you would like to know what is the constant for the quadratic equation 9 * y = 4 * x^2, you can calculate this using the following steps:
<span>9 * y = 4 * x^2 /9
</span>y = 4 * x^2 / 9
y = 4/9 * x^2
The correct result would be B. 4/9.
Answer: x= 1, 
Step-by-step explanation:
The quadratic equation is

and

So we just need to sub in the proper numbers from the equation given, in this case, it would result in

and

Once we get this we can either manually simplify or use a calculator, using a calculator would result in the answers
x= 1, 
Answer:
7/3
Step-by-step explanation
4y+8=29-5y
First you are going to subtract 8 from both sides of the equation.
4y=21-5y
Next you are going to add 5y to each side of the equation.
9y=21
Now write it as a fraction,
9/21
Last but not least simplify.
3/7
