Answer:
1) Solution (2,-3)
2) Solution (-1, 
)
3) Solution (
)
Step-by-step explanation:
We need to solve equations using elimination
1) 
Let:
Adding both equations:
We get value of x = 2
Now, put value of x into equation 1 to find value of y
So, we get y = -3
Solution (2,-3)
2) 
Let:
Adding both equations
We get: y= -3/2
Now find value of x by putting value of y in eq(1)
We get x = -1
Solution (-1, )
3) 
let:
Add both equations:
We get x = -1/2
Now, put value of x in equation 2
We get y = -5/2
Solution ()
Answer:
4x^4y + 20x^2y^2 - 28x^3y
Step-by-step explanation:
4xy(x^3 + 5xy - 7x^2)
= 4xyx^3 + 4xy * 5xy - 4xy * 7x^2
= 4x^2y + 4xy * 5xy - 4xy * 7x^2
= 4x^4y + 20x^2y^2 - 4xy * 7x^2
= 4x^4y + 20x^2y^2 - 28x^3y
Answer:
1/2 of 4/5 = 1/2 of four fifths = two fifths
Step-by-step explanation:
1/2 x 4/5 = 4/10
4/10 simplified is 2/5
4 divided by 2 = 2
---- ----
10 divided by 2= 5
Answer: There are lots of common polar curves that are bounded therefore a polar curve is not always bounded all the time. A polar curve is required to have an unbounded function (right side of r = f(Θ)) to be an unbounded polar. An example of an unbounded curve would be r = Θ for 0 ≤ Θ.
