Answer:

x>-8

Step-by-step explanation:

5 − (x + 5) > −2(x + 4)

Distribute the minus sign and the -2

5 - x -5 > -2x-8

-x > -2x-8

Add 2x to each side

-x+2x > -2x+2x-8

x>-8

Kristina used synthetic division to divide the polynomial f(x) by x−2, as shown on the table. What is the value of f(2)? −14 −11

UNO [17]

Answer:

-11

Step-by-step explanation:

The answer to the first one sould be -11

2x^3 +5x^2−x−6

Write 5x^2 as 4x^2 + x^2......and we have.....

2x^3 + 4x^2 + x^2 - x - 6

2x^2 ( x + 2) + ( x + 2)(x - 3)

(x + 2) [ 2x^2 + x - 3]

(x + 2) (2x +3) (x - 1)

x^3−4x^2−3x+18 = 0

Using some synthetic division, we have

3 [ 1 - 4 -3 18 ]

3 -3 -18

_______________

1 -1 -6 0

The remaining polynomial is x^2 - x - 6 which factors as (x - 3) ( x + 2)

So .... the factored form is (x - 3) ( x - 3) ( x + 2) = ( x + 2) ( x - 3)^2 = 0

What is the equation of the line that has a slope of -3 and passes through the point (4,-2)

sukhopar [10]

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0 or (0,y))

You know m = -3, so you can plug it into the equation

y = mx + b

y = -3x + b

To find "b", plug in the point (4,-2) into the equation

y = -3x + b

-2 = -3(4) + b

-2 = -12 + b Add 12 on both sides

10 = b

y = -3x + 10 Your answer is B

Elements in a Circle

Before drawing the 8 required elements in the circle, let's recall some basic definitions:

Chord: A straight line whose extremes both lie on the circle
Tangent: A straight line that touches the circle in one point and is perpendicular to the radius at the point of tangency
Radius: It's a straight line from the center of a circle to its circumference
Secant: It's a line that that intersects the circle in exactly two points
Point of tangency: Is the point where the tangent line touches the circumference
Diameter: It's a straight line from one point to the circle going through the center.
Minor arc: Is an arc of a circle that measures less than or equal to 180 degrees
Mayor arc: Is an arc of a circle that measures more than 180 degrees

Please refer to the image below to see all the elements described above
