It's 3/4 because (y2-y1)/(x2-x1)
numerator = top part of the fraction
denominator = bottom part of the fraction
* means multiply
a.
you can only add the numerator when the denominator is the same
cant add the denominator
denominator has to be the same
1/5 = 4/20
4/20 + 7/20 = 11/20
b.
1 7/8 = 15/8
3/4 ÷ 15/8 =
3/4 * 8/15 =
24/60 = divide both top and bottom by 12 =
2/5
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,
![(x +2)^2=a](https://tex.z-dn.net/?f=%28x%20%2B2%29%5E2%3Da)
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>
![(1 +2)^2=a\\(3)^2=a\\9=a\\a=9](https://tex.z-dn.net/?f=%281%20%2B2%29%5E2%3Da%5C%5C%283%29%5E2%3Da%5C%5C9%3Da%5C%5Ca%3D9)
Thus, the value of the <em>a, </em>in the provided quadratic equation for which Nancy found one solution as x=1 is 9.
