Answer:
v = ± 
Step-by-step explanation:
Given
E = 
( multiply both sides by 2 to clear the fraction )
2E = mv² ( divide both sides by m )
= v² ( take the square root of both sides )
v = ±
Answer:
y ≤ 1/3 x - 1.3.
Step-by-step explanation:
First find the equation of the line:
The slope = (-0.3 - (-1.3) / (3 - 0).
= 1/3 so the equation is y = 1/3x + b where b is a constant.
b is the y-intercept which is the value of y when x = 0 . We see that it is -1.3 ( from the point 0, -1.3).
Since the line is continuous and the shading is below this line the inequality sign is 'less than or equal to', ≤.
Answer:
The best thing to do here is to put each of these into fractions, with the total (31) as the denominator.
14/31= silver
6/31= black
8/31= copper
3/31= various colours.
As you're looking for the keys that are silver or copper, you've got to add the two denominators together, which gives you 14+8= 22.
This cannot be simplified further, therefore, the probability of choosing either a silver or copper key is 22/31.
Hope this answer helps you :)
Have a great day

Answer is 264
4y-5x=20
. Just give numbers for x or y . Then, find the x value or y value from the equation.
Remember that y-axis is the vertical and x-axis is the horizontal line.
For example, just give x = 0 . 4y=20 y = will be 5 .
Now, write these on your graph.
As you see, 0 means orijin point , but if y=5 , use vertical line for writing 5.
Then, find the values while x=1 , x=2 ,and also x= -1 , x= -2 .
Finally, find the points from the connection of x and y points.
Then, combine all of connected points as a curve .
