By definition
... sec(θ) = 1/cos(θ) . . . . trig identity
... sec(θ) = 1/(9/10) . . . . substitute the given value, then simplify to ...
... sec(θ) = 10/9
First, multiply 5 • x, which is 5x. Then, multiply 5 • 1, which is 5. Now you have the equation 5x + 5 = -20. Now, subtract 5 from +5 and do the same to the -20, which gets you -25. Now divide -25 by 5, which is -5. Therefor, x= -5. Check by multiplying -5 • 5, which is -25. Then add -25 + 5, which is 20 and you now know your answer is correct.
Final Answer: x = -5
Answer:
The slope is 0
Step-by-step explanation:
X1, y1 = (-5,-3)
x2, y2 = (-5, -6)
distance =√[(x2-x1)^2 + (y2-y1)^2]
=√[(-5 + (-5))^2 + (-6+(-3))^2]
= √(100+81)

Answer:
151-4=147÷3=49+1=50
151+4=155÷2=77.5×50=3875
3875 is the answer
