Answer:105
Step-by-step explanation:55-66=74 74times
Answer:
A- b: the y value when y changes; the point where a line crosses the v-axis
B- m: What happens to y when x is one; the ratio of the y change to the x change
C- k: The y value when x is zero b x increases by one
Step-by-step explanation:
If this is about slope intercept form as i think it is
C sounds a little bonkers in this case though because when y is zero then x increases by one
Answer:
Obtuse Angle
Step-by-step explanation:
It is greater than 90˚
QUESTION 1
The given system of equations are:
We equate the two equations to get:
When x=0,
The solution is (0,1)
QUESTION 2
The given equations are:
and
We equate both equations to get:
Group similar terms,
We put x=0 into any of the equations to find y.
The solution is (0,-1).
QUESTION 3
The given equations are:
and
We equate both equations:
Group similar terms:
This is not true.
Hence the system has no solution.
If the track is 10km long, and X travels at 40 km/h, it will take 1 hour to do 4 laps. this means that car X will do one lap in 15 minutes. Y travels at 30 km/h, which means it will do 3 laps in 1 hour, meaning that car X will do 1 lap in 20 minutes.
X- 15, 30, 45, 60
Y-20, 40, 60
Therefore, after an hour, they will pass again.
