2|7 − 7x| = 2x + 4
|7 - 7x| = x + 2
7 - 7x = x + 2 or 7 - 7x = -(x + 2)
-8x = -5 or 7 - 7x = -x - 2
x = 5/8 or -6x = -9
x = 5/8 or x = 9/6
x = 5/8 or x = 3/2
To check for extraneous solutions, we check both solutions in the original equation.
<em>Check solution 5/8:</em>
2|7 - 7x| = 2x + 4
|7 - 7x| = x + 2
|7 - 7 * 5/8| = 5/8 + 2
|56/8 - 35/8| = 5/8 + 16/8
21/8 = 21/8
<u>Solution x = 5/8 works.</u>
<em>Check solution 3/2:</em>
2|7 - 7x| = 2x + 4
|7 - 7x| = x + 2
|7 - 7 * 3/2| = 3/2 + 2
|14/2 - 21/2| = 3/2 + 4/2
|-7/2| = 7/2
7/2 = 7/2
<u>Solution 3/2 also works.</u>
Answer: x = 5/8 or x = 3/2
Answer: He is more likely to win more money than lose money, but he has a equal chance of winning/losing.
The answer is number B
Answer:
y = 2/3x - 3
Step-by-step explanation:
First calculate the slope: y2 - y1 divided by x2 - x1
Slope: -6/-9 = 2/3
The y-intercept is -3
The equation of a line: y = mx + b
y = 2/3x - 3
This is the answer for the calculation
Answer:
1. YES, BECAUSE WITH TAX, IT WOULD BE 9.88
2. MOVE THE DECIMAL OVER TO THE LEFT BY ONE PLACE
ANSWER IS 5.356
Step-by-step explanation:
IF TAX IS 13% YOU MULTIPLE 8.75 BY 1.13. YOU GET 1.13 FROM THE ORIGINAL PRICE PLUS .13 IN TAX.
