it’s 321 because whether negative or positive it’s absolute value
A=4 b=-10 c=5
10+-√100-(4)(4)(5)/8
10+-√20/8
10+-2√5/8
x= (5+√5)/4 and x =(5-√5)/4
the parentheses just mean that it is all over 4
Given,
y = -3x+1 (EQ1)
y = 2x-4 (EQ2)
Equate EQ1 and EQ2
EQ1 = EQ2
-3x+1 = 2x-4
-3x-2x = -4-1
x = 1
y = -3x+1
y = -3(1)+1
y = -3+1
y = -2
(1, -2)
