If A(x', y') & B(x",y") the the distance AB is given by the following formula:

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

**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.**

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.

QUESTION POSTED AT 28/03/2020 - 12:36 PM

**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)

**Answer:**

Height of the dam is 45.45 meters.

**Step-by-step explanation:**

From the attached figure, AB is the height of dam NM is Scarlett's height. We have to find the height of the dam. NM = CB = 1.65 m

Using trigonometric equations as:

**AC = 43.8 m**

**So, the height of the dam is AC + CB = 43.8 m + 1.65 m = 45.45 m**

**Hence, the height of the dam is 45.45 meter.**

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.
