Answer:

k = - 6

Step-by-step explanation:

Since (x - 2) is a factor then x = 2 is a root

Substitute x = 2 into the polynomial and equate to zero, that is

2³ + k(2)² + 12(2) - 8 = 0

8 + 4k + 24 - 8 = 0

4k + 24 = 0 ( subtract 24 from both sides )

4k = - 24 ( divide both sides by 4 )

k = - 6

Answer:

ax + ab

Step-by-step explanation:

Step 1: Write expression

a(x + b)

Step 2: Distribute a to each term

ax + ab

[tex]\huge\boxed{Hello!}[/tex]

The Distributive Property states that

a(b+c)=ab+ac

Now, let's use this property to simplify the given expression:

a(x+b)

ax+ab

This is our final answer.

Answer:

every integer is a whole number

Answer:

let the number be a.

now,

5a-13=10

or, 5a= 10+13

or, a = 23/5

or, a = 4.6

therefore, the number is 4.6

Answer:

48 meters squared or 48m^2

(Both are correct. Whichever you prefer is fine.)

Step-by-step explanation:

The formula to find area is A=height*base

So since the base = 6 and height = 8

Just multiply to combine the two

6*8=48

If you want to show with only numbers write this.

A=b*h

6*8=48

48 meters squared or 48m^2

y-2=5(x--8)

Step-by-step explanation:

Formula for point slope form equation: y-y1 = m(x – x1)

After that just plug in the given numbers

Answer:

C (-6,-8) → C' (6,8)

D (-2,-8) → D' (2,8)

E (-2,-4) → E' (2,4)

F (-6,-4) → F' (6,4)

Step-by-step explanation:

When you rotate a point 180° counterclockwise about the origin, the point A (x,y) becomes A' (-x,-y). So, if the points are positive, they will become negative.

Because all the points are negative, rotating them 180° counterclockwise will make them positive.

Hope that helps.

The expression for temperature change in City A is 9 + (-8)

The amount the temperature changes for City A = 1°F

The expression for temperature change in City B is -1 + (-3) = -4°F

The amount the temperature changes for City B = -4°F

Based on the available data:

The expression for that represents the temperature change from 8 am to 10 am is, therefore;

The temperature change from 8 am to 10 am are

Sum, change from 8 am to 10 am = 9 + (-8) = 1°F

The temperature change from 8 am to 10 am are

Sum, change from 8 am to 10 am = -1 + (-3) = -4°F

Answer:

Step-by-step explanation:

Answer:

1. No vertical compression or stretching but will open up downward.

2. 1/4 vertical stretch

3. 4 vertical compression

Step-by-step explanation:

Any time your dealing with vertical stretching or compression it will always be the number before the parentheses.

So in 1. it is - or basically -1 which means the parabola will be open up downward. And in this problem there is no stretching or compression

2. Is the 1/4 is a vertical stretch

3. 4 is a vertical compression.

Or what also could help is when the number before the parentheses is bigger such as number 4 the closer together the parabola will be. And the smaller the number like 1/4 the wider the parabola will be.
