Given: 
1. Combining like terms (here terms 6x and 2x both contain x, then we can combine them):
2. Distributive postulate:
The equation is
3. Zero product postulate (zero product postulate state that if a product of two factors is equal to zero, then first factor is equal to zero or second factor is equal to zero):
4. Subtraction property of equality:
a) subtract 6 from the first equation:
b) subtract 2 from the second equation:
Answer:
49.3%
Step-by-step explanation:
37 / 75 = 49.3%
Answer:
8
Step-by-step explanation:
The formula for the area of a square is s^2, where s is the length of one side. 64 is a perfect square, so square root it and you find that one side is 8.
Answer:
See below
Step-by-step explanation:
<em>Quadratic function is in general form of:</em>
- <em>y = ax^2 + bx + c</em>
<em>The function has a minimum if a > 0 and maximum if a < 0</em>
<em>The minimum or maximum point is a vertex of the graph</em>
- <em>A vertex is the point x = -b/2a</em>
<em>When b = 0, the min or max point equals to value of c.</em>
- 33. It has maximum of -1
- 34. It has minimum of 7
- 35. It has minimum at x = - 8/4 = -2
f(-2) = 2*(-2)^2 + 8(-2) + 7 = 8 - 16 + 7 = - 1
- 36. It has maximum at x = -18/2(-3)= 3
g(3) = -3*3^2 + 18*3 - 5 = -27 + 54 - 5 = 22
- 37. It has minimum at x = - 6/(2*3/2) = - 2
f(-2) = 3/2*(-2)^2 + 6(-2) + 4 = - 6 - 12 + 4 = - 14
