<span>Slope-intercept form is y = mx + b
m is the slope
b is the y-intercept
7x = 14y - 8
7x + 8 = 14y {added 8 to each side}
(1/2)x + (8/14) = y
slope is 1/2
A line perpendicular would have a slope of -2 {the negative reciprocal of 1/2}
#1 y = -2x - 7 {it is the only one with a slope of -2}</span>
So if one bit of the length, is half the size of the other bit then we can make the following equation, for x being the length of rope:
x + 2x = 66
3x = 66
x = 22
That is the length, of the smaller one (half the big one), so 2x = 44. Hence d) is your answer.
Hope I helped!

This should be answered with the mean. The lower the mean, the lower the score it took to get the mean. So B is the answer.
I think it’s d. A percent is out of 100 so it’s 156/100
Answer:
16
Step-by-step explanation:
you do 2+2 which is 4 then 8/2 is 4 and you multiple 4*4
