Answer:
(-4,-6),(-2,-5),(0,-4),(4,-2)
Step-by-step explanation:
(x,y)
x represents the x co-ordinate of a point
y represents the y co-ordinate of a point
It is given in the question that the end of a pendulum with a length of 21 cm travels an arc length of 24 cm.
So here radius is 21 cm and the arc length is 24 cm .
Now we use the arc length formula , which is
Where s is the arc length and r is the radius.
Substituting these values, we will get
And now we need to convert radian to degree, and for that we have to multiply by
That is
Answer: C) three times a number minus two is more than 16
Explanation: < represents greater than
Answer:
The answer to your question is There is only one solution (0, -2)
Step-by-step explanation:
Data
Equation 1 x - y = 2
Equation 2 x + y = -2
Solve for y
Equation 1 y = x -2
y = x - 2
Equation 2 y = - x - 2
See the graph below
These lines cross in point (0 ,-2), that is the only solution.
If the lines have not crossed, they were parallel lines.
