Answer:
x=-20
Step-by-step explanation:
add 17 to both sides
-37 + 17 =-20
11H=C. The independent variable is how much she gets paid an hour
Answer:
perpendicular = 10.24 cm
Step-by-step explanation:
by pythagorus theorem,
![h {}^{2} = b {}^{2} + h {}^{2}](https://tex.z-dn.net/?f=h%20%7B%7D%5E%7B2%7D%20%20%3D%20b%20%7B%7D%5E%7B2%7D%20%20%2B%20h%20%7B%7D%5E%7B2%7D%20)
( where, h = hypotenuse, b = base,
p = perpendicular )
so,
=》
![13 {}^{2} = 8 {}^{2} + p {}^{2}](https://tex.z-dn.net/?f=13%20%7B%7D%5E%7B2%7D%20%20%3D%208%20%7B%7D%5E%7B2%7D%20%20%2B%20p%20%7B%7D%5E%7B2%7D%20)
=》
![169 = 64 + p {}^{2}](https://tex.z-dn.net/?f=169%20%3D%2064%20%2B%20p%20%7B%7D%5E%7B2%7D%20)
=》
![169 - 64 = p {}^{2}](https://tex.z-dn.net/?f=169%20-%2064%20%3D%20p%20%7B%7D%5E%7B2%7D%20)
=》
![p = \sqrt{105}](https://tex.z-dn.net/?f=p%20%3D%20%20%5Csqrt%7B105%7D%20)
perpendicular = 10.24 ( root 105 )
The missing exponent of 1/169=(1/13)
Two equations are given
b+t <=9
30b + 20t > 200
WE graph each inequality
b + t <= 9
Make a table for b + t < = 9
b --- > t
0 --> 9
2 --> 7
Plot the point and make a graph. WE shade the bottom region because we have <= symbol
The graph is attached below.
WE graph the inequality
30b + 20t > 200
Make a table for 30b + 20t > 200
b --- > t
0 --> 10
6 --> 1
Plot the point and make a graph. WE shade the upper region because we have > symbol
The intersection of shaded region is our solution.
