△GHD ≅ △EDH by SAS Congruency , so Option A is the right answer.
<h3>What is a Triangle ?</h3>
A triangle is a polygon with three sides , three angles and three vertices.
It is given that
∠GHD and ∠EDH are right
GH ≅ ED Triangles G H D and E D H overlap and intersect at point F.
The triangles share side H D.
Sides G H and E D are congruent.
angles G H D and E D H are right angles.
Given that in triangles GHD and EDH
∠ GHD ≅ ∠ EDH (given)
GH = ED, (given)
side HD= HD (common side )
△GHD ≅ △EDH (side angle side )
Therefore, the correct option is A

Y- Axis
Bc it is being reflected from the Y- Axis
Answer:
y= (-9/2)*x-5/2 or 2y+9x+5=0
Step-by-step explanation:
given the following equation
y² = 5*x⁴ - x²
we can take the derivative with respect to x in both sides to get the slope of the tangent line , and knowing that y=f(x) we can apply the chain rule , therefore
d(y²)/dx = d(5*x⁴ - x²)/dx
2*y*dy/dx = 5*4*x³ - 2*x
dy/dx = (10*x³-x)/y
replacing values (x=-1,y=2)
m=dy/dx = (10*(-1)³-(-1))/2 = -9/2
now from the equation of the line
y= m*x+h
we know that (x=-1,y=2) belongs also to the line since it is tangent to the curve, thus
2= (-9/2)*(-1) + h
h = 2 - 9/2 = (-5/2)
thus
y= (-9/2)*x-5/2
or
2y+9x+5=0
Answer:
9
Step-by-step explanation:
Take half of the coefficient of x and square it.
-6/2 = -3
Square -3 to get 9.
Answer: 9
Step-by-step explanation:
z = b - ma
z - b = ma
z - b / m = a
