Question

Please help:
Solve for x: 5|2x − 2| + 8 = 18

Answer 1

Part 1: Create an absolute value equation that has no solutions. Explain why this equation has no solutions. Part 2: Create an absolute value equation that has one solution. Explain why this equation has one solution. Part 3: Create an absolute value equation that has two solutions. Explain why this equation has two solutions.

Answer 2

Assume a 115 pound person burns 36 calories after 12 minutes of walking and 54 calories after 18 minutes of walking.
Part 1 (2 points): Use calories as the y−coordinate and minutes as the x-coordinate. After writing two ordered pairs, find the slope. What does the slope represent in terms of the information provided?
Part 2 (2 points): Write an equation, in slope intercept form, to represent this data.
Part 3 (2 points): How many calories will this person burn after 35 minutes of walking? Using complete sentences, explain how the equation, slope, or graph can help to predict calories burned.

Answer 3

thats all

Answer 4

\[5|2x-2|+8=18\]ou have to isolate the absolute value (2x-2)\[5|2x-2|=10\]\[|2x-2|=2\]now you have to account for the outcome being both negative and positive like this\[2x-2=2~~~~~~~~~~2x-2=-2\]\[2x=4~~~~~~~~~~~~~~~~2x=0\]\[x=2~~~~~~~~or~~~~~~~x=0\]

Answer 11

Part 1: Create an absolute value equation that has no solutions. Explain why this equation has no solutions.
|x| = -2 (no solutions) ... guess why???
Part 2: Create an absolute value equation that has one solution. Explain why this equation has one solution.
|x-2| = 0 (one solution) ... guess why??
Part 3: Create an absolute value equation that has two solutions. Explain why this equation has two solutions.
|x| = 2 (two solutions) ... guess why??

Answer 12

Assume a 115 pound person burns 36 calories after 12 minutes of walking and 54 calories after 18 minutes of walking.
Part 1 (2 points): Use calories as the y−coordinate and minutes as the x-coordinate. After writing two ordered pairs, find the slope. What does the slope represent in terms of the information provided?
http://www.wolframalpha.com/input/?i=Plot+points+ {%2812%2C36%29%2C+%2818%2C+54%29}
Part 2 (2 points): Write an equation, in slope intercept form, to represent this data.
use this formula:
y - y1 = (y2 -y1)/(x2 - x1) * (x-x1)
Part 3 (2 points): How many calories will this person burn after 35 minutes of walking? Using complete sentences, explain how the equation, slope, or graph can help to predict calories burned.
y - y1 = (y2 -y1)/(x2 - x1) * (35-x1)
put ^^ 35 in this equation

Answer 13

and your
((x1,y1),(x2, y2)) -> {(12,36), (18, 54)}
