Answer:
the vertex is (1,-1)
Step-by-step explanation:
y = −3x^2 + 6x − 4
the vertex is at
h= -b/2a where ax^2 +bx+c
h= -6/2(-3)
h= -6/-6
h=1
substitute this in to find the y value
y = -3(1)^2 +6(1)-4
y = -3+6-4
y = -1
the vertex is (1,-1)
Answer: nonsense
Step-by-step explanation:
7x+3=5(x-3)+2x
7x+3=5x-15+2x
7x+3-5x+15-2x=0
18=0

Answer:
$31.8
Step-by-step explanation:
Assuming the 6% tax is separate from the $30, we can use this equation:
Total = Cost + Tax (pretty self explanatory)
Method 1
Total = $30 + (6% * $30)
Total = $30 + $1.8
Total = $31.8
Method 2
Total = $30 * 1.06 (The 1 is the original cost, the .06 is the 6% tax)
Total = $31.8
<span>Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own.But these things will change direction of the inequality: ...<span>Don't multiply or divide by a variable (unless you know it is always positive or always negative)</span></span>
just use the standart recursive for geometric sequence
