Answer:
Option 1: {-7,5,18,24,32}
Step-by-step explanation:
Observing the number line we can see that the solution is
x≤18 and x>22
So we will check the options one by one
For {-7,5,18,24,32}
The number set satisfies the solution translated from the number line.
For {-9,7,15,22,26}
As this number set includes 22 which is not included in the solution so this option is not correct.
For {16,17,22,23,24}
This number set also includes 22 so the option is not correct.
For {18,19,20,21,22}
This number set includes 19,20,21,22 which is not a part of the solution. Therefore, this option is also not correct ..
Answer:
see explanation
Step-by-step explanation:
• Parallel lines have equal slopes
• The slopes of perpendicular lines are the negative reciprocal of each other
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 7x + 2y = 7 into this form
Subtract 7x from both sides
2y = - 7x + 7 ( divide all terms by 2 )
y = -
x +
← in slope- intercept form
with slope m = - ![\frac{7}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B2%7D)
Thus
slope of perpendicular line = ![\frac{2}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B7%7D)
slope of parallel line = - ![\frac{7}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B2%7D)
71.25 . First, I did 19/2 = 9.5. Then, I multiplied 9.5 by 7.50 to get 71.25
