Answer:
x = 5 and x = 1 are the factors
Step-by-step explanation:
<h2>step 1) </h2>
identify the a, b, and c values (a=1 b= -6 c=5)
<h2>step 2) </h2>
plug them into the quadratic formula
x = -(-6) ± √(-6)² - 4(1)(5) / 2(1)
<h2>step 3) </h2>
multiply -1 by -6 to get 6
x = 6 ± √(-6)² - 4(1)(5) / 2(1)
<h2>step 4)</h2>
multiply -6 by -6 to get 36
x = 6 ± √36 - 4(1)(5) / 2(1)
<h2>step 5)</h2>
multiply 4 by 1 to get 4
x = 6 ± √36 - 4(5) / 2(1)
<h2>step 6) </h2>
multiply 4 by 5 to get 20
x = 6 ± √36 - 20 / 2(1)
<h2>step 7)</h2>
subtract 36 by 20 to get 16
x = 6 ± √16 / 2(1)
<h2>step 8) </h2>
take the square root of 16 to get 4
x = 6 ± 4 / 2(1)
<h2>step 9)</h2>
multiply 2 by 1 to get 2
x = 6 ± 4 / 2
<h2>step 10) </h2>
add 6 by 4 to get 10
x = 10 / 2
<h2>step 11) </h2>
divide 10 by 2 to get 5 (now you know the first factor is x=5)
x = 5
<h2>step 12)</h2>
subtract 6 by 4 to get 2
x = 2 / 2
<h2>step 13)</h2>
divide 2 by 2 to get 1 (now you have found the final factor x=1)
<h2>step 14)</h2>
you know know that the factors of x²- 6x + 5 are<em><u> x = 5 and x = 1</u></em>
Y = 12x - 40
the x variable represents the number of hours Sam works at the airport
the y value represents the amount in dollars that Sam has after paying Daniel
the 12 is the amount in dollars that Sam earns per hr
the 40 is the amount in dollars Sam owes Daniel
Answer: 40%
Step-by-step explanation:
There are 70 cookies in total.
The gingerbread cookies number 28.
The percentage that are gingerbread will therefore be:
= Number of gingerbread/ Total number of cookies * 100%
= 28 / 70 * 100%
= 40%
