Answer:

The roots of the polynomial are;

3 + 2i

and 3-2i

Step-by-step explanation:

Here, we want to solve the given polynomial using the completing the square method

We start by dividing through by 8

This will give;

x^2 - 6x = -13

To complete the square, we simply divide the coefficient of x by 2 and square it

We have this as -6/2 = -3

square it;; = (-3)^2 = 9

Add it to both sides

x^2 - 6x + 9 = -13 + 9

x^2 - 6x + 9 = -4

(x-3)^2 = -4

Find the square root of both sides

x-3 = ±2i

x = 3 + 2i

or x = 3-2i

Grandma is making her grandson french toast. The pan can only fit two pieces of bread at a time. To cook each side of the bread
Anni [7]

Grandma should be able to make three slices of French toast by slicing one of the original slices into two.

<h3>How can grandma make three slices of French toast?</h3>
  • Put two slices of bread in the pan and cook them for one minute (first minute)
  • Turn both slices over and cook ( second minute)
  • Remove both slices and slice one of this into two. This will mean the new slices will have one side cooked and another one that is not cooked.
  • Cook these thinner slices  (third minute).
  • The result would be three cooked slices, although two of them would be thinner.

If fg + gh = fh,which of the following statements must be true?
Oksanka [162]
The only safe conclusion is that point G lies on line FH or that point G lies somewhere between line FH. We cannot conclude that point G is the midpoint of line FH eventhough by virtue of definition of midpoint, the given equation is a proof equation. If G were to be midpoint, segment FG must be equal to segment GH in line FH.

5(2x + 4) = 50 (Given) 10x + 20 = 50 (Distributive Property) 10x = 30 (?) x = 3 (Division Property) Fill in the missing reason f
mestny [16]

We go from 10x+20 = 50 to 10x = 30 after we subtract 20 from both sides. So we use the subtraction property (of equality).

Answer:

2 and - \frac{1}{2}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3y = 6x + 9 ( divide all terms by 3 )

y = 2x + 3 ← in slope- intercept form

with slope m = 2

(i)

Parallel lines have equal slopes, thus

the slope of line t is 2

(ii)

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{2}, thus

the slope of line r is - \frac{1}{2}
