Which represents the solution(s) of the graphed system of equations, y = –x2 + x + 2 and y = –x + 3? (1, 2) (1, 2) and (0, 3) (–1, 0) and (2, 0) (2, 1)
y = -x^2 + x + 2
y = -x + 3
-x + 3 = -x^2 + x + 2
x^2 - x - 2 - x + 3 = 0
x^2 -2x + 1 = 0
(x - 1)(x - 1) = 0
x - 1 = 0 y = -x + 3
x = 1 y = -1 + 3
y = 2
solutions are : (1,2) , (1,2)
Answer:
(1,2) , (1,2)
Step-by-step explanation:
Given : \(y = -x^2 + x + 2\)
\(y = -x + 3\)
To Find : Which represents the solution(s) of the graphed system of equations
Solution:
\(y = -x^2 + x + 2\)
\(y = -x + 3\)
Now, to find the solution
\(-x + 3 = -x^2 + x + 2\)
\(x^2 - x - 2 - x + 3 = 0\)
\(x^2 -2x + 1 = 0\)
\((x - 1)(x - 1) = 0\)
So, \(x = 1,1\)
Substitute the value of x
\(y = -x + 3\)
\(y = -1 + 3\)\(y = 2\)
Thus the solutions are : (1,2) , (1,2)
