Answer:
<em>Set the function equal to 0</em>
Step-by-step explanation:
<u>Standard Form of the Quadratic Equation</u>
The form
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:
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:
Answer: Set the function equal to 0
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%
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 <==
Answer:
I'm pretty sure it's H
Step-by-step explanation:
25/100 is 25% times 8/x
Answer:
see explanation
Step-by-step explanation:
step 4 take the square root of both sides
= ± 
x + 4 = ±
step 5 subtract 4 from both sides
x = - 4 ±
step 6 solve for x
x = - 4 - or x = - 4 +
