Answer:

Option C is correct.

Step-by-step explanation:

y = x^2+4x+5

We need to find the vertex of the above equation.

The above equation represents the parabola.

The slope of parabola can be found by taking derivative of the given equation

dy/dx = 2x+4

The slope of the parabola at the vertex is zero SO,

2x+4 = 0

2x = -4

x = -4/2

x = -2

Putting value of x =-2 to find the value of y

y = x^2+4x+5

y =(-2)^2+4(-2)+5

y = 4-8+5

y =9-8

y = 1

So, the vertex is (-2,1)

Option C is correct.

How do i solve 2x(n 3) ??
forsale [732]
<span>Simplifying 2x + n = 3
 
Reorder the terms: n + 2x = 3
 Solving n + 2x = 3
 
Solving for variable 'n'.
 
Move all terms containing n to the left, all other terms to the right.
 
Add '-2x' to each side of the equation. n + 2x + -2x = 3 + -2x
 
Combine like terms: 2x + -2x = 0 n + 0 = 3 + -2x n = 3 + -2x
 
Simplifying n = 3 + -2x</span>

Which is the equation for ---
ratelena [41]
Equation of the line: 
y=mx+b
Ordinate at the origin (where the line cut the y-axis): b=1

B=(-5,5)=(xb,yb)→xb=-5, yb=5
C=(0,1)=(xc,yc)→xc=0, yc=1
m=(yc-yb)/(xc-xb)
m=(1-5)/(0-(-5))
m=(-4)/(0+5)
m=(-4)/(5)
m=-(4/5)

y=mx+b
y=-(4/5)x+1
Multiplying the equation by 5:
5[y=-(4/5)x+1]
5y=-4x+5
Adding 4x both sides of the equation:
5y+4x=-4x+5+4x
4x+5y=5

Answer: The equation for BC is: Third option 4x+5y=5
