Factorise fully the following:
a) x^2 + 3x
b) 2x^2- 8x
c) 6x + 9x^3
d) 12x^3- 4x^2​

Think of a mirror, something that produces your reflection. The Y axis is the line that is vertical on the graph.

D) Is not the answer because it does not reflect over the y-axis.

B) Is not the answer because the figure is not reflected, even though it went across the y-axis.

C) Is not the answer because it reflected over the x-axis, not the y-axis.

Therefore, your answer is A)

The figure is reflected across the y-axis and each figure faces one another.

Answer:

rational because they end

Step-by-step explanation:

Answer:

27.5 and 11.5 are both rational numbers.

Step-by-step explanation:

This is because they do not continue on forever. You know what they are. So numbers like 1, 1.5, 1.234, and 100 are rational. Numbers like pi, 1/3 (1.33333 forever) are irrational.

Answer:

N = L/P

8/3 pieces

Step-by-step explanation:

Length of the board = 5/6 ft

A carpenter wants to cut a board that is five sixth ft long into pieces that are five sixteenths ft long.

Length of each piece = 5/16 ft

Number of pieces that can be cut from the board = Total length of board / length of each piece

Let

N = Number of pieces that can be cut from the board

L = Total length of board

P = length of each piece

N = L / P

= 5/6 ÷ 5/16

= 5 / 6 × 16 / 5

= 80 / 30

= 8/3

The number of pieces that can be cut from the board is 8/3

Answer:

Answer:

b. The slope is -10, and the y-intercept is 1.

Step-by-step explanation:

Y = slope(x) + y-intercept

Answer: B) slope = -10, y intercept = 1

The general form is y = mx+b

m = slope

b = y intercept

Comparing y = -10x+1 to y = mx+b we see that

m = -10

b = 1

The simplest form of the function is f(x) = x2. The graph is a parabola often called the basic parabola.

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.

here, we have,

Three different parabolas exist. Vertex form, standard form, and intercept form are the three forms. You can access a unique key feature for the graph on each form.

Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve.

Solve f{x}=x-2?

f(x)=x-2    x∈R

x≤0

x-2≤2

Range of f(x)=[∞,2)

9. Which of the following statements are true? Check the boxes of the true statements.

and, attached below.

Answer:

Step-by-step explanation:

The translation rule:

The parent function is translated 5 units to the right and 7 units up.

Let the functions f(x) and g(x) be two real functions.

And g (x) = f (x) + k, where k is real numbers.

The function can be sketched by shifting f (x), k units vertically.

The direction of shift can be found by the value of k:

if k > 0, the base graph shifts k units up, and

if k < 0, the base graph shifts k units down.

The function provided by the basic function f(x) and the constant

g(x) = f(x - k),

may be drawn by horizontally moving the f(x) k unit coordinates.

The shift's direction depends on the value of k. Specifically,

The base graph moves k units to the right if k > 0, and

The base graph moves k units to the left if k < 0.

To graph the function g(x) = ∛(x - 5) + 7, we need to transform the parent function f(x) = ∛x.

We can achieve this transformation by first translating the function 5 units to the right and then 7 units up.

This is because the "x - 5" inside the cube root shifts the function horizontally to the right by 5 units, and the "+7" outside the cube root shifts the function vertically up by 7 units.

Therefore, the correct answer is to translate the parent function 5 units to the right and 7 units up.

The answer is -3<x≤2

Answer:

[tex]\frac{22}{3}[/tex] = b

or

7[tex]\frac{1}{3}[/tex] = b

(they are the same value, just different ways of writing it)

Step-by-step explanation:

4 = -[tex]\frac{2}{3}[/tex] (5) + b

simplify

4 = -[tex]\frac{10}{3}[/tex] + b

now use inverse operations

4 = -[tex]\frac{10}{3}[/tex] + b

+[tex]\frac{10}{3}[/tex]  +[tex]\frac{10}{3}[/tex]

[tex]\frac{22}{3}[/tex] = b

Answer:

24º

Step-by-step explanation:

90-66 = 24º. So since complementary angles are 2 angles that add up to 90 degrees. That means that 66 + x = 90 using the information given. Then we use algebra and get that x =24. Therefore the answer is 24º.

Answer:

The supplement of 66° is the angle that when added to 66° forms a straight angle (180° ).

Step-by-step explanation:

A supplementary angle is an angle that equals 180°. So now we know that the two angles added together will give us 180°, we can use this to check at the end.

Let's call the smaller angle x

We also know that the larger number is 66° more than the smaller. This gives us:

x+x+66°=180°.

x is equal to the smaller angle, and the second angle is (x) - the smaller number with an extra 66°, giving us the difference.

Now we can simplify this by subtracting 66° from both sides.

Answer: x is greater than 9 x>9

Step-by-step explanation:

You see -4 times 9 equals to -36. And -36+plus 40 equals to -4. The question is asking you to make sure the left side is greater. So, it has to be greater than 9. for example -4 times 8 equals to -32. And -32+40 equals to 8. So your answer is X>9. I hope that helped you.

Answer:

25 is the 14th term.

Step-by-step explanation:

The nth term of a sequence is given by the following explicit rule:

f(n) =5.5n - 52

We need to find the position n of the term of value 25. In other words, find n in the equation:

5.5n - 52=25

Adding 52:

5.5n =25+52=77

Solving:

n=77/5.5

n=14

25 is the 14th term.

Answer:

46 (23%)

Step-by-step explanation:

If 10% of x is 20, we can assume that 100% of x is 200. This is because since 10% is such a nice number to work with, we can simply add a zero to the end of it and the number. Now, we can see that 50% is 100 and 25% is 50. 20% is 40 and 10% is 20. 5% is 10 and 1% is 2. That being said, we need to do 50% + 3%. Which leaves us with 50 (25%) - 4 (2%). That being said, the answer is 46 (23%).

Answer:

-4

Step-by-step explanation:

To solve, you need to isolate the number with the variable (in this case, 4n). To do that, get rid of the 20 on the left side. To do THAT, do the opposite which is subtract; do it to both sides. This leaves you with 4n= -16.

Now, to get rid of the 4 and be left with just the n, do the opposite of what is given. In this case, n is multiplied by 4 so divide by 4 on both sides to isolate n. This gives you the answer of -4.
