Which is the best first step to write this in standard form?
goldenfox [79]

Answer:

<em>Set the function equal to 0</em>

Step-by-step explanation:

<u>Standard Form of the Quadratic Equation</u>

The form

ax^2+bx+c=0

is called the standard form of a quadratic equation. It can be clearly identified the terms of a second-degree polynomial equated to 0.

The equation is given in the form:

2(x-4)^2-3=8

And we need to operate the expression to make it look like a standard form. The first logical step should be to set the function equal to 0 and then start to operate the resulting expression. It can be done by subtracting 8 on both sides of the equation:

2(x-4)^2-3-8=0

Answer: Set the function equal to 0

The​ U.S.-based motorcycle manufacturer says that it expects to build 139,000 motorcycles this​ year, up from 126, 000 last year
german

The formula is (new-original)/original.

(139,000 - 126,000)/126,000

= 13,000/126,000

= .103

Now, convert the decimal into a percent by moving the decimal two places to the right and including the percent sign.

.103 = 10.3%

Answer: 10.3%

John paid $32.16 for groceries. This included 7% sales tax. What was the cost of groceries before the sales tax? A. $2.25 B. $30
hoa [83]
If 32.16 includes the sales tax....then the price before the sales tax will be less then 32.16

that only leaves 2 choices.....
so lets check them...
7% sales tax on 2.25 = 0.07(2.25) = 0.16....so if u spent 2.25 on groceries and added the sales tax of 16 cents....then u would have spent 2.41...thats a long way from 32.16

if u spent 30.06...with 7% sales tax....u would spend 30.06 + 0.07(30.06) = 32.16

so the cost of the groceries before the sales tax is 30.06 <==

The first three steps of completing the square to solve the quadratic equation x^2 + 8x +5 = 0, are shown below.
evablogger [386]

Answer:

see explanation

Step-by-step explanation:

step 4 take the square root of both sides

\sqrt{(x+4)^2} = ± \sqrt{11}

x + 4 = ± \sqrt{11}

step 5 subtract 4 from both sides

x = - 4 ± \sqrt{11}

step 6 solve for x

x = - 4 - \sqrt{11} or x = - 4 + \sqrt{11}
