Answer: The derivative of the function 
is 
.
Step-by-step explanation:
We know that the derivative of 
with respect to x is given by :
(1)
The given function is
Differential both sides with respect to x , we get
( Using (1))
Therefore , the derivative of the function is .
Answer:
The value of the expression is 382
Step-by-step explanation:
x = 77 and the expression given is 5x - 3
5x - 3
input the given
5(77) - 3
solve
5 times 77 is 385
so now we have
385 - 3 which equals 382
so our final answer is 382
Answer:
Equation Form:
x=7,y=−2
Step-by-step explanation:
Multiply each equation by the value that makes the coefficients of x
opposite.
(−1)⋅(2x+5y)=(−1)(4)
2x−2y=18
Simplify.
−2x−5y=−4
2x−2y=18
Add the two equations together to eliminate x
from the system.
(−2x−5y=−4) +(2x−2y=18) = (-7y=14)
Divide each term by −7 and simplify.
y=−2
Substitute the value found for y into one of the original equations, then solve for x.
x=7
The solution to the independent system of equations can be represented as a point. (7,−2)
The result can be shown in multiple forms.
Point Form:
(7,−2)
Equation Form:
x=7,y=−2
