Answer:

Option D. two complex roots

Step-by-step explanation:

we know that

In a quadratic equation of the form ax^{2} +bx+c=0 the discriminant D is equal to

D=(b^{2}-4ac)

in this problem we have

3x^{2} -2x+1=0  

so

a=3\\b=-2\\c=1

substitute the values

D=(-2^{2}-4(3)(1))

D=(4-12)

D=-8

The discriminant is negative

therefore

The quadratic equation has two complex roots

HELP! will give brainlest or whatever its called... Triangle ABC has vertices A(–2, 3), B(0, 3), and C(–1, –1). Find the coordin
Tomtit [17]

Answers:

A ' = (-2, -3)

B ' = (0, -3)

C ' = (-1, 1)

=======================================================

Explanation:

To apply an x axis reflection, we simply change the sign of the y coordinate from positive to negative, or vice versa. The x coordinate stays as is.

Algebraically, the reflection rule used can be written as (x,y) \to (x,-y)

Applying this rule to the three given points will mean....

  • Point A = (-2, 3) becomes A ' = (-2, -3)
  • Point B = (0, 3) becomes B ' = (0, -3)
  • Point C = (-1, -1) becomes C ' = (-1, 1)

The diagram is provided below.

Side note: Any points on the x axis will stay where they are. That isn't the case here, but its for any future problem where it may come up. This only applies to x axis reflections.

A student factors a6 - 64 to (a2 - 4)(a4 + 4a2 + 16).Which statement about (a2 − 4)(a4 + 4a2 + 16) is correct?
IrinaK [193]

Answer:

Option (b) is correct.

The expression is equivalent, but the   term is not completely factored.

Step-by-step explanation:

Given :  a student factors  to

We have to choose the correct statement  about   from the given options.

Given   is factored to

Consider    

Using algebraic identity,

comparing  and b = 4, we have,

Thus, the factorization is equivalent but we can simplify it further also, as

Using algebraic identity,

Thus,

Can be written as

Thus, the expression is equivalent, but the   term is not completely factored.

Option (b) is correct.

Solve this system of equations<br>{2x + y = 11<br>{5x - y = 10​
34kurt

Answer:

solution:  (3, 5)

Step-by-step explanation:

Solve this system of equations

{2x + y = 11

{5x - y = 10​

add the equations to use elimination method.

2x + 5x + y - y = 11 + 10;

7x = 21

x = 21/7 = 3

x = 3

y = 11 - 2x = 11 - 2*3 = 11 - 6 = 5
