Step-by-step explanation:
- Masses of the bodies are x and y
- Distance at which they are kept is r
- When two bodies are of masses x and y are placed at a distance r then the gravitational force acting on them is given as:
- Where G is the gravitational constant.
Answer:
2x^9(6x^3+x^2-4x+5x^-9)
Step-by-step explanation:
2x^9(6x^3+x^2-4x+5x^-9)
The answer is
Exact form: -35/18
Decimal form:-1.94444444...
Mixed number form: -1 17/18
Algebra always makes things sound harder than they actually are, and weird vocabulary can mix up the steps we knew so well.
Part 1: Multiply the first equation by a 2 so that you can cancel out the y variable.
6x - 2y = 0
5x + 2y = 22
Part 2: Actually cancel out the y variables, and combine like terms.
11x = 22
Part 3: Solve for "x" by dividing both sides by 11
x = 2
Part 4: Substitute the variable "x" with the value we just solved for in the original equation.
3(2) - y = 0
6 - y = 0
Then, solve for y by adding y to both sides
6=y
Solution Set = {2,6}
Answer:
9, y=9
Step-by-step explanation:
So, there is one thing we always need to remember to find the y intercept.
This is that the y intercept can always be found on the middle line of the graph, when x is at 0.
What we must do is look at the graph, look at where the function hits x=0, and see what the y value is.
In this case, when x equals 0, we can see that y is 9.
So the y intercept is 9.
Hope this helps! :D
