QUESTION POSTED AT 26/03/2020 - 02:29 PM

Let's consider all of the possible arrangements for words that DO NOT have the x-letter in it.

Start by drawing a line for the five available slots:

_ _ _ _ _

These will represent the different arrangements of letters.

Since letters may be repeated, these are independent events, meaning the previous does not affect the concurrent term.

Thus, we can have 25 of the 26 different letters, since we're not counting the x.

The second slot can have 25, as well as the third, fourth, and fifth.

We can simplify this to become:

Now, let's consider all of the ways in which a five letter word can be made. Using the same logic, we get:

[tex\text{Arrangements: } 26^{5}[/tex]

Thus, the total number of ways in which we can arrange a 5-letter word with at least one X in it is:

The calculator should do the rest.

It's D: (0,0)

This is because when you put 0 in for x your y value will equal 0 and that is one of your answers, so it's the point (0,0)

**Answer:**

**C) Horizontal compression **

**Step-by-step explanation:**

Since, if y = f(x) is a function,

Then y = a f(x) gives a **vertical stretch** if **a > 1** and gives a **vertical compression** if **0 < a < 1.**

Also, y = f(bx) gives a **horizontal stretch** when** 0 < b < 1** and gives a **horizontal compression** if **b > 1**.

Here,

The given parent function is,

f(x) = 2x

And, 3 > 1

Thus, by the above statements,

f(3x) will give a horizontal compression.

Hence, **Option C is correct.**

QUESTION POSTED AT 28/03/2020 - 12:43 PM

If you want an answer to question: You can make the equations equal to each other and solve for x. So, since the y values are the same, we can do

(+x)5x+6 = -x-7. (+x)

(-6)6x+6= -7(-6)

(1/6) x 6x= -13 x (1/6)

x= -13/6

Substitute −13/6 for x in y=5x+6:

y=5x(−13/6) + 6

y = -29/ 6.

**y= -29/6 and x= -13/6**

(+x)5x+6 = -x-7. (+x)

(-6)6x+6= -7(-6)

(1/6) x 6x= -13 x (1/6)

x= -13/6

Substitute −13/6 for x in y=5x+6:

y=5x(−13/6) + 6

y = -29/ 6.

**Answer:**

The function started facing up with a vertex at (0,0) since 7 was added before squaring , the graph shifts 7 units up so the vertex at (7,0) also , the function is negative do the graph is pointing down.

This means that there are two x- intercepts in g(x) and there was one x- intercepts in f(x).

Choice A. Work done below:

4x-1=5x-8 ( Set the opposite sides equal to each other).

4x-5x-1=-8 (Subtract 5x on both sides)

-x-1=-8 (Combine like terms)

-x=-8+1( Add 1 on both sides)

-x=-7 (Now since you have a negative sign on both sides you can cancel them)

x=7 ( Making that as your answer!!)

4x-1=5x-8 ( Set the opposite sides equal to each other).

4x-5x-1=-8 (Subtract 5x on both sides)

-x-1=-8 (Combine like terms)

-x=-8+1( Add 1 on both sides)

-x=-7 (Now since you have a negative sign on both sides you can cancel them)

v(x)=(s/t)

= (3x - 6) / (-3x+6)

= [3(x-2)] / [-3(x-2)] --> 3 is factored out

= 1/-1 ---> common terms are cancelled out.

= -1 ---> This is the
simplified formula.

To find the domain, we equate the denominator to 0.

-3x+6 = 0

3x = 6

x = 2

Domain: all values except 2.

w(x)=(t/s)(x)

= (-3x+6)x / (3x-6)

= [-3x(x-2)] / [3(x-2)] --> 3 is factored out

= -x --> The common terms are cancelled out. This is the simplified formula.

Solving for domain:

3x-6 = 0

3x = 6

x = 2

Domain: all values except 2.

2) y=0

3) x=3

4) 2y + (3*3y) = -15

11y=-15

y = -15/11

5) 4x + 7x + 63 = 19

11x = -44

x = -4

1)2x=4 -> 4/2 = 2 so x=2

**Step-by-step explanation:**

Given : Maria will spin the arrow on the spinner 2 times.

To find : What is the probability that the arrow will stop on the same letter twice.

Solution : We have given a spinner that spin twice and stop on the same letter.

Formula for probability = .

Here, total part of spinner = 3 and it spin two times

So, total possible outcome = 6. Arrow ston on same letter twice( favorable outcome) =2.

Plugging the values in formula :

Probability = .

Probability = .

**Therefore, probability that the arrow will stop on the same letter twice = (c).**

Period: the length of one full cycle of the cos graph. On the unit circle it is the circumference. The distance around a circle with radius = 1.

Domain: the x value or the values on the horizontal axis. On the unit circle these would be the radian measures around the unit circle such as pi/6, pi/4,

pi/3, pi/2.

Range: the y value or the values on the vertical axis. On the unit circle it would be the cosine value for each radian measure. Such as cos pi/4 = (sqrt2)/2, cos pi/3= 1/2.

X-intercepts: the points where the graph crosses the horizontal axis. On the unit circle these are the cosine values when theta is at the vertical points of the unit circle, pi/2 and 3pi/2.
