It should be 180 degrees cuz “x” is a flat line
Answer:
y = 2x -5
Step-by-step explanation:
Given points: (0,-5) (1,-3)
(x1, y1) = (0,-5)
(x2, y2) = (1,-3)
Calculate the slope:
m = (y2 - y1)/(x2 - x1)
m = [-3 - (-5)] / [1 - 0]
m = (-3 + 5) / 1
m = 2/1 = 2
Next, the y-intercept is the value of y when x = 0. One of your given points is the y-intercept, (0, -5). The y-coordinate is the value of b.
Therefore, the linear equation is: y = 2x -5

Answer:
k=-2
Step-by-step explanation:
-1*-2=2
-1*-2=20*-2=0
-1*-2=20*-2=02*-2=-4
-1*-2=20*-2=02*-2=-45*-2=10
Answer:
<u>25 minutes</u>
Step-by-step explanation:
From the table,
2 laps takes time 10 min.
4 laps takes time 20 min.
6 laps takes time 30 min.
8 laps takes time 40 min.
10 laps takes time 50 min.
So, we can deduce the relation between the number of laps and time
the time over the number of laps at each row = 5
Which mean 1 lap takes 5 minutes
Therefore, to run 5 laps, it takes = 5 * 5 = 25 minutes
Answer:
6%
Step-by-step explanation:
Estimated distance = 80 miles
Actual distance covered = 75.5 miles
We need to find the percent error of the cyclist's estimate. Its formula is given by :
Put all the values,
or
= 6%
So, the percentage error is 6%.
