The value of the <em>a, </em>in the provided quadratic equation for which Nancy found one solution as x=1 is 9.
<h3>What is the solution of equation?</h3>
The solution of the quadratic equation is the solution of the variable of the equation, for which the equation satisfies.
Nancy found that x=1 is one solution to the quadratic equation. The quadratic equation is,
For this equation, one solution is <em>x</em>=1. Put this value in the above equation to get the value of <em>a,</em>
Thus, the value of the <em>a, </em>in the provided quadratic equation for which Nancy found one solution as x=1 is 9.

Answer:
20x-8y+ 7/20
Step-by-step explanation:
Answer: 13
Step-by-step explanation:
Equilateral triangle means that all sides are equal
Soo
3x + 1 must be equal to 5x - 9
3x + 1 = 5x - 9
-2x = -10
x = 5
Substitute x as 5 into either side value
3(5) + 1 = 15 + 1 = 16
So, all sides equal 16
Which means that y + 3 also equals 16
y + 3 = 16
y = 13
= 20y + 3y -4(-2y)
= 20y + 3y + 8y
= 31y
In short, Your Final Answer would be 31y
Hope this helps!
X=y-4 Let's make this eqn 1 and
2x-5y=3 this eqn 2..
Two things are possible here...
Its either you substitute for x in equation 2... Or you substitute for y...
x=y-4 put this in the equation 2..
2x-5y=3.. Replace the x with (y-4)
2(y-4)-5y = 3...
Since this is In the option no point in substituting for y...
Hope this helped...?
