Hello :
<span>y = –2x² +6x – 1.
y = -2(x²-3x)-1
y= -2( x² -2(3/2)x +(3/2)² - </span>(3/2)²)-1
y = -2((x-3/2)² -9/4))-1
y = -2(x-3/2)² +7/2
the <span>axis of symmetry is the line : x = 3/2 and vertex : (3/2 , 7/2 ) </span>
Answer:
Step-by-step explanation:
Equation
3x + 9 + 2x = x - 2x - 3
Solution
Combine all the like terms.
3x+2x+9 = x - 2x - 3
5x + 9 = -x - 3 Add x to both sides of the equation
5x+x +9 = -x+x -3 Combine
6x + 9 = - 3 Subtract 9 from both sides of the equation
6x+9-9 = - 3-9 Combine
6x = -12 Divide both sides by 6
6x/6 = -12/6
x = - 2
Answer x = - 2
