ΔTXV is an <span>isosceles triangle because ∡T = ∡X therefore TV = VX.
3x - 24 = 2x + 1 |subtract 2x from both sides
x - 24 = 1 |add 24 to both sides
x = 25

Answer:
x=2. or. x=8
Step-by-step explanation:
x^2-10x+16=0. s=-10
x^2-8x-2x+16=0. p=16
x(x-8)-2(x-8)=0. [-8,-2]
(x-2)(x-8)
x=2. or. x=8
Answer:
Step-by-step explanation:
Equation of line k is y = (-4/7)x + 1
point (-5,-10); m = -4/7
Line L is perpendicular to k so the perpendicular slope will be 7/4
Equation of line L is (y - y1) = m(x-x1)
y+10 = (7/4) (x +5)
4y + 40 = 7x + 35
4y = 7x - 5
y = (7/4)x - (5/4)
Answer:
Relative minimum:
, Relative maximum: 
Step-by-step explanation:
First, we obtain the First and Second Derivatives of the polynomic function:
First Derivative
(1)
Second Derivative
(2)
Now, we proceed with the First Derivative Test on (1):


The critical point is
.
As the second derivative is a constant function, we know that critical point leads to a minimum by Second Derivative Test, since
.
Lastly, we find the remaining component associated with the critical point by direct evaluation of the function:


There are relative maxima.
