PLEASE HELP what is an equation of the line?

Mathematics

The equation of line is y+3=2(x+2)

Option A is correct.

Step-by-step explanation:

We need to find the equation of the line.

Looking at the graph the two points are: (2,5) and (-2,-3)

We will first find the slope of these points using formula:

Slope=\frac{y_2-y_1}{x_2-x_1}

Here x₁ = -2, y₁=-3, x₂=2 and y₂=5

Putting values and finding slope

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{5-(-3)}{2-(-2)}\\Slope=\frac{8}{4}\\Slope=2

So, slope of the line is 2.

Considering that both lines are parallel (as not given in question). both lines will have same slope.

Now using Point slope form to find the equation.

y-y_1=m(x-x_1)

Using point (-2,-3) and slope m= 2

y-y_1=m(x-x_1)\\y-(-3)=2(x-(-2))\\y+3=2(x+2)

So, the equation of line is y+3=2(x+2)

Option A is correct.

You are standing in one big palace where a king and his 5 queens stay. Each queen has 5 rooms. In each room there are 5 big cats
Paladinen [302]
(5+1+1)*2 + 5*5*5*(1+5)*4 = 3014
Rooms = 5*5 = 25
Cats per room = 5 + 5*5 = 30
All cats legs = 25*30*4 = 3000
All humans = 1+1+5 = 7
All humans legs = 7*2 = 14
All legs = 3000 + 14 = 3014

Given the trinomial 2x*2 + 4x + 4, predict the type of solutions. a. Two rational solutions b. One rational solution c. Two irra
OverLord2011 [107]

Answer:

d. Two complex solutions

Step-by-step explanation:

We have been given a trinomial 2x^2+4x+4 and we are supposed to predict the type of solutions of our given trinomial.

We will use discriminant formula to solve for our given problem.

\text{Discriminant}=b^2-4ac, where,

a =\text{Coefficient of }x^2,

b =\text{Coefficient of }x,

c =\text{Constant }

Conclusion from the result of Discriminant are:

D

D=0\text{ means one real zero with of multiplicity two}

D>0\text{ means two distinct zeroes}

Upon substituting our given values in above formula we will get,

\text{Discriminant}=4^2-4*2*4

\text{Discriminant}=16-32

\text{Discriminant}=-16

Since our discriminant is less than zero, therefore, out given trinomial will have two complex solutions and option d is the correct choice.
