f(x) = x^2 + 16x
Completing the square.
f(x) = a(x-h)^2 + k
f(x) = (x + 8)^2 - 64
h = -8, k = -64
Vertex = (h,k)
Vertex = (-8, -64)

Answer:
After discount: $829.49. Savings is $355.50
Step-by-step explanation:
We are going to use a GE Dishwasher. The price listed is: $1184.99. If you had a 30% off coupon, The price after the discount is: $829.49. You would save $355.50
Multiply 1184.99 by .30 this will give you savings
Next subtract the savings 1184.99 - 355.50= 829.49.

Answer:
Please check the explanation.
Step-by-step explanation:
Given that we have to determine the expressions which are equivalent to 20 percent of 150.
First, we need to determine what actually 20 percent of 150 really brings.
i.e
20% of 150 = 20/100 × 150
= 30
Thus,
20% of 150 = 30
Therefore, any expression that is equivalent to 30 will be included in the answer to this question.
Answer:

Step-by-step explanation:
because it says in your thing up above to exchange but there is a 50% im wrong
C = 220T + 1890.
Solve the equation for T.
220T = C - 1890
T = C/220 - 8.6
The steel produced is expected to be sold at a price of $310 per ton.
310 $/ton is a rate or slope. Write a linear equation where x is tons of steel produced and y is selling price of the steel.
y = 310x
Write and solve an equation to find the amount of steel produced if the selling price is equal to the cost of production.
* Here, note that the cost of production and tons of steel in the first equation is in the millions. The equation we just wrote for the selling price was in x tons of steel. This only matters in regards to the units you specify because; million/million = 1
The unit multiplier of all variables must be specified as same. Either everything is in millions or not.
Here, I'll leave everything in millions, change x (tons of steel) to T (mill tons steel) and "y" to "S" in million dollars selling price.
S = 310T
Set equal to Cost equation.
220T + 1980 = 310T
Solve for T, million tons of steel produced.
1980 = 310T - 220T
1980 = 90T
T = 1980/90
T = 22 million tons steel produced
