Answer:
Step-by-step explanation:
solid line means >=
y >= x+1
dotted line mean >
y > -x-2
combining
the system of inequalities is y >= x+1 and y > -x-2
Answer:
16
Step-by-step explanation:
Given the equation,
, let's solve for x as follows,
Subtract 200 from both sides


Subtract 15x from both sides


Divide both sides by -5


Use this word problem just change the numbers
Answer:
x=4
Step-by-step explanation:
Divide both sides by 6.
Complete the square:
<span>y = 3x^2 - 12x + 4 </span>
<span>y = 3(x^2 - 4x) + 4 </span>
<span>y = 3(x^2 - 4x + 4 - 4) + 4 </span>
<span>y = 3(x^2 - 4x + 4) - 12 + 4 </span>
<span>y = 3(x - 2)^2 - 8</span>
