i think its c hop this help sorry if it dont
(4) Halving the value of b
Example #1:
a = 4 , b = 2
x = (4^2) / 2
x = 16 / 2
x = 8
a = 4 , b = 1
x = (4^2) / 1
x = 16 / 1
x = 16
Example #2:
a = 8 , b = 4
x = (8^2) / 4
x = 64 / 4
x = 16
a = 8 , b = 2
x = (8^2) / 2
x = 64 / 2
x = 32
Answer:
I'm not exactly sure but I think it is 8.5
Step-by-step explanation:
I did 12-3.5=8.5
Answer:
1 hour 37 minutes
Step-by-step explanation:
From the image attached, we can see the start and end time represented by the clock. To calculate the length of time that Maria and her friends rode, we just have to subtract the start time from the end time.
From the end time clock, we can see that the end time is 2:24, while from the start time clock, we can see that the start time is 12:47. Hence, the length of time they rode is:
Length of time for bike ride = 2:24 - 12:47 = 1 hour 37 minutes
If they are all in a line then we can find the equation of their line using: y = mx + b
First find m using points (2,5) and (3,3)
m = (5-3)/(2-3) = 2/-1 = -2
Now using (3,3) and m= -2 to solve for b:
3 = -2(3) + b
3 = -6 + b
9 = b
So our equation is y = -2x + 9
That is the solution for question b)
Now to find the mystery point, solve:
1 = -2x + 9
-8 = -2x
4 = x
So our mystery point is (4,1)
So for part a) the answer is k = 4
