Point slope formula: y-y1=m(x-x1). Answer: y-7=6(x-(-4))
4x^2 + 5xy - y^2 = 6
Implicitly differentiating both sides,
4(2x) + 5(x y' + y) - 2yy' = 0
where y' = dy/dx
8x + 5xy' +5y -2yy' = 0
combining y' terms
y' (5x-2y) +8x +5y = 0
y'(5x-2y) = -(8x+5y)
dy/dx = -(8x+5y)/(5x-2y)
or
dy/dx = (8x+5y)/(2y-5x)
B=8.5 all that you have to do is add the inverse of the number that's no b
Answer:
Total Price = 1.07(0.65x)= 0.6955x.
Step-by-step explanation:
The discount percentage is, <em>d</em>% = 35%.
The sales tax percentage is, <em>s</em>% = 7%.
The variable <em>x</em> represent the original cost of the item(s).
The discount is subtracted from the original amount.
So, the discounted amount will be, 0.65x.
And the sales tax is added to the original amount.
So, the value of tax plus price will be, 1.07x.
Then the final price of the item(s) will be:
Total Price = 1.07(0.65x)= 0.6955x.
<h3><u>Solution:- </u></h3>
Let the number to be added be A
Now,

Transposing (−5x³+ 4x − 3 ) to other side-

Remember if there is a -ve sign before a bracket the signs of whole of the terms changes on opening bracket

Putting like terms together -


Therefore, 5x³+x²-5x +2 should be added to −5x³+ 4x − 3 to get x²− x − 1
