50 mph y=50x+25 where x is hours traveled and y is total distance
The gradient is the slope right?
If yes, then your answer is -4.
m=(y2-y1)/(x2-x1)
m=(10-2)/(-2-0)
m=-4
Answer:
D = n/5 - m^2
Step-by-step explanation:
work:
n = 5(m^2 + D)
distribute the 5
n = 5m^2 + 5D
move the 5 to the other side by subtracting from both sides
n - 5m^2 = 5D
Divide both sides by 5 to isolate D
n/5 -m^2 = D
use reflexive property to get the answer on the left side
D = n/5 - m^2
Answer: For no solution it would mean that there is no answer to the equation. For infinite solutions it would mean that any value for the variable would make the equation true.
Explanation: For example of no solution 6=5 as you can tell 6 is not the same to 5 so there is no solution. More examples are 2=3, 8=10, and 1=0. For infinite solutions examples are 2=2, 7=7, and 10=10 as we can see 2 does equal 2 and 7 equals 7 which makes it true and infinite.
