Answer:2.8333
Step-by-step explanation:
Answer: -x
step-by-step explanation:
convert the mixed numbers to improper fractions 125/6 = 77/6
77/6x-14x+1/6x
77/6x-14x+1/6x = -1 times x
= 1 times x
multiply 1 times x = x
= x
E.) 15/53
F.) 15/53
G.) 18/53
H.) 12/53
Answer:
Step-by-step explanation:
f(x,y)=10-x^2-y^2
To find derivative of z w.r.t. x is treat any other variable as a constant.
dz/dx=0-2x-0
dz/dx=-2x
Evaluating this at (7,-3) gives us dz/dx=-2(7)=-14.
Since this result is negative, it mrans as x increases z decreases.
f(x,y)=10-x^2-y^2
To find derivative of z w.r.t. y is treat any other variable as a constant.
dz/dx=0-0-2y
dz/dx=-2y
Evaluating this at (7,-3) gives us dz/dy=-2(-3)=6.
Since this result is positive it mrans as y increases z decreases.
