Answer:
1). Y= x² -4x+6
Y = 3x-4
2) X= 5 and x= 2
3).
X= 5
Y= 11
X= 2
Y= 2
Step-by-step explanation:
1).
Y = (x-2)²+2
Y= x² -4x+4+2
Y= x² -4x+6
Y+4= 3x
Y = 3x-4
2).
Y = x² -4x+6
Y = 3x-4
x² -4x+6= 3x-4
X² -7x+10= 0
X²-5x-2x+10= 0
X(x-5)-2(x-5)= 0.
(X-5)(x-2)= 0
X= 5 and x= 2
3). substituting the value of x into the linear equation
Y = 3x-4
X= 5
Y= 3(5)-4
Y= 15-4
Y= 11
Y = 3x-4
X= 2
Y= 3(2)-4
Y= 6-4
Y= 2
