Answer:
Step-by-step explanation:
1. add the side lengths

Answer: y = 2x - 2
Explanation: The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
y = mx + b
Subtract 2x from both sides of the equation.
-y = 2 - 2x
Multiply each term in -y = 2 - 2x by -1
(-y) . -1 = 2 . -1 + (-2x) . -1
Multiply (-y) . -1
Multiply -1 by -1
Multiply y by 1
y = 2 . -1 + (-2x) . -1
Simplify each term
Multiply 2 by -1
y = -2 + (-2x) . -1
Multiply -1 by -2
y = -2 + 2x
Reorder -2 and 2x
y = 2x - 2
What are the medians for the height and weight distribution, respectively?
A. 170, 179
B. 183, 167
C. 167, 183
D. 179, 170
E. 165, 175
Arranged Height distribution (cm): 154, 158, 159, 163, 165, 167, 167, 174, 177, 178, 181, 186, 191
Arranged Weight distribution (lbs): 157, 163, 168, 173, 173, 177, 183, 184, 187, 189, 190, 192, 193
The median is the middle number. [there are 13 numbers each. hence the respective median are the 7th numbers]
Median Height = 167
Median Weight = 183
Answer: 
<u>Step-by-step explanation:</u>
Notes: Coefficients condense to exponents.
Subtraction condenses to division

1 day = 750 m
1 * 7 = 750 * 7
7 days = 5250 m
Now, since 1 km = 1000 m, this means in order to convert from meters to kilometers you must divide by 1000
5250 / 1000
= 5.25 km
Or, you could do the hard way by going to wolfram alpha / google and typing 5250 m to km.
Hope this helps!
