Answer:
x^2 - 25 ✔
Step-by-step explanation:
(x+5)(x-5)
x(x-5) +5(x-5)
x^2 - 5x + 5x - 25
x^2 - 25

Step-by-step explanation:
Slope=9
i)
When line is parallel
y+5=9(x-6)
y+5 = 9x - 54
<h3>59 = 9x-y </h3>
When line is perpendicular
y+5=-1/9(x-6)
9(y+5)= -1(x-6)
9y + 45 = -x+6
<h3>
x+9y = -39</h3>

Answer:
(2,-3)
x=2 y=-3
Step-by-step explanation:
2x+y=1 y=1-2x
3x+2y=0
3x+2(1-2x)=0
3x+2-4x=0
-x+2=0
-x=-2
x=2
2x+y=1
2(2)+y=1
4+y=1
y=-3
Answer:
Option B.
Step-by-step explanation:
Option A.
f(x) =
Derivative of the given function,
f'(x) =
=
=
Since derivative of the function is negative, the given function is decreasing.
Option B. f(x) =
f'(x) =
=
=
Since derivative is positive, given function is increasing.
Option C. f(x) =
f'(x) =
=
=
Since derivative is negative, given function is decreasing.
Option D. f(x) =
f'(x) =
=
Since derivative is negative, given function is decreasing.
Option (B) is the answer.
