Answer:
(2,-3)
x=2 y=-3
Step-by-step explanation:
2x+y=1 y=1-2x
3x+2y=0
3x+2(1-2x)=0
3x+2-4x=0
-x+2=0
-x=-2
x=2
2x+y=1
2(2)+y=1
4+y=1
y=-3

<h2>
The greatest possible value of the second root, β = 54 </h2>
Step-by-step explanation:
The given quadratic equation:
Let α and β be the roots of the given quadratic equation.
α = 36
To find, the greatest possible value of the second root ( β) = ?
∴ The sum of the roots,
α + β =
⇒ 36 + β =
⇒ 5m = 36 + β ............. (1)
The product of the roots,
α.β =
⇒
⇒ ............. (2)
From equations (1) and (2), we get
⇒
⇒
⇒
⇒ β(β - 54) - 24(β - 54) = 0
⇒ (β - 54)(β - 24) = 0
⇒ β - 54 = 0 or, β - 24 = 0
⇒ β = 54 or, β = 24
∴ The greatest possible value of the second root, β = 54
Alright let’s see the question
There are 360 degrees in a circle. That means that we first divide 360 by 9. We have the measure for one of the nine parts of the circle, but we need two. All we do is multiply 40 by 2 to get 80 degrees.
