Answer:

x=7

Step-by-step explanation:

Step 1: Put the variables and constants on the same side and change their signs so it'll look like this 5x-2x = 28 - 7, you always move the smaller number to either the left or right depending on its position in the problem.

Step 2: solve each side normally like this, 3x = 21

Step 3: to get x by itself divide 3 on both sides and you should get x=7

Here's a run through of the steps

5x+7=2x+28

   -7       -7(subtract 7 from both sides

5x=2x+28-7

-2x   -2x(subtract 2x from both sides)

5x-2x=28-7

3x=21

3x/3 = 21/3 (divide 3 from both sides)

x=7

Respond to each of the following questions. Be sure to include and thoroughly describe each transformation.
sergeinik [125]

Answer:

31. 1) Vertical shift up 4 units.

     2) Horizontal shift right 1 unit.

     3) Vertically stretched by a factor of 3.

32. g(x)=-(x+3)^2+7

Step-by-step explanation:

Some transformations for a function f(x) are shown below:

- If f(x)+k, the function is shifted up "k" units.

- If f(x)-k, the function is shifted down "k" units.

- If f(x+k), the function is shifted left "k" units.

- If f(x-k), the function is shifted right "k" units.

- If -f(x), the function is reflected over the x-axis.

- If bf(x) and b>1, the function is stretched vertically by a factor of "b".

31. Given the function f(x)=x^{2} and the function g(x) = 3(x - 1)^2 + 4, we can notice that the transformations from the graph of f(x) to the graph of g(x) are:

1)  f(x)+k

2)  f(x-k)

3)  bf(x), being b>1

Therefore, we can conclude that the transformations necessary to transform the graph of f(x) to the graph g(x) are:

1) Vertical shift up 4 units.

2) Horizontal shift right 1 unit.

3) Vertical stretch by a factor of 3.

32. Knowing the parent function:

 f(x)=x^{2}

And given the transformations:

1) Reflection over the x-axis.

2) Horizontal shift left 3 units.

3) Vertical shift up 7 units.

We can define that the function g(x) is:

g(x)=-(x+3)^2+7

The miniature pinscher weighs 0.12 times the weight of a Doberman pinscher that weighs 32.65 kilograms. How much does the miniat
anastassius [24]

Answer:

3.918kg

Step-by-step explanation:

Given parameters:

 Doberman Pinscher weight  = 32.65kg

Unknown:

 Miniature Pinscher weight = ?

Solution:

From the first sentence;

       Miniature Pinscher's weight is  0.12 times Doberman Pinscher

   Miniature Pinscher's weight  = 0.12 x 32.65kg

 

Miniature Pinscher's weight  = 3.918kg
