Type of lines ?  Not the best question.
Answer: Perpendicular, first choice
The little 90 degree angle indicator at the intersection marks these lines as meeting at a right angle, which is called perpendicular.
 
        
                    
             
        
        
        
Answer:
(5,-3)
Step-by-step explanation:
Rewrite the equation in vertex form
y =-(x-5)^2 - 3
You take the value of -5 (that would be your x value) and change it to the opposite sign -> +5
Then you take -3 (that would be your y value) and take it as it is
therefore the answer is (5, -3)
 
        
             
        
        
        
Answer:
7 friends
Step-by-step explanation:
Given the inequality expression
17(g+2)+45.99<200
We are to find the value of g that satisfies the inequality
Expand
17g+34 +45.99<200
17g+79.99<200
Subtract 79.99 from both sides
17g+79.99-79.99<200-79.99
17g<120.01
g<120.01/17
g<7.059
Hence the max number of friend that can attend is 7friends.
 
        
             
        
        
        
Answer:
   4π in ≈ 12.57 in
Step-by-step explanation:
One full revolution (2π radians) is made in 60 minutes. In 40 minutes, the hand moves through an angle θ of (40/60)(2π) = 4π/3 radians. The length of the arc is ...
   s = rθ = (3 in)(4π/3) = 4π in ≈ 12.57 in
