Answer:
1m/s^2
Step-by-step explanation:
the formula for acceleration is change in velocity divided by time
the change in velocity is 4m/s (subtract 5 from 9)
the change in time is 4 seconds
so 4m/s ÷ 4s
this gives you 1m/s^2
Answer:
The second option you listed: x + y = 4 gives the same line as H, and therefore renders infinite number of solutions (as many as every point on the line)
Step-by-step explanation:
We need to look for the equation that exactly matches the given one :
2 x + 2 y = 8
notice dividing both sides of this equation by "2" we get:
x + y = 4
SO this equation represents exactly the same line as 2 x + 2 y = 8 does, and therefore their graphs overlap completely
Answer: 45cm
Step-by-step explanation:
The spring stretches 1/3 of the weight attached. 1/3 of 15 is 5. However, the spring is already 40cm long so we must add 5 to 40 to find the total length and of the spring.
Vertical lines have undefined slope. They are not y=mx+b equations, but simply x= equations.
This line passes through the point (-1,12) has an x-value of -1. Therefore the equation of the line is simply x=-1
