Step-by-step explanation:

Answer:

Step-by-step explanation:

Dilation of a line about a point not on the line shifts the line but leaves the slope intact .

New line slope will be -2

As both A and C lie on a horizontal line y = 2, C' will also lie on the same line

The distance between A and C is 0 - 2 = -2

a scale factor of 3 means C' is -2(3) = -6 units left of A

C' = (2 - 6, 2) = (-4. 2)

Answer:

  3340

Step-by-step explanation:

The even digits in our number system are 0, 2, 4, 6, 8. Any integer with one of these digits in the ones place is an even number. Even numbers are divisible by 2.

Of the numbers listed, only 3340 is an even number. 3340 is divisible by 2.

Answer:

Ф = 19.80 °

Step-by-step explanation:

by using pythagoras theorem

h² = p² + b²

13² = 5² + b ²

b = √194

b = 13.93

now

tanФ  = p/b

Ф = tan¬1( 5 / 13.93)

Ф = 19.80 °

Answer:

About 4 months give or take

Step-by-step explanation:

Answer:

C. 4 months

Step-by-step explanation:

In order to find what is the equivalent number of months in 120 days, we can apply the following methods:  

Since there are 30 days in one month, then we can establish the following proportion statement in colon form:

30 days: 1 month = 120 days : x months

The expression of proportion in colon form, (a : b = c : d):

We could also establish the proportion statement in fraction form (ratio):

     [tex]\large \mathsf {\frac{30\:days}{1\:month}\:=\:\frac{120\:days}{x\:months}}[/tex]

Then, use the Cross-product property, which involves the multiplication of extremes and the means:

30 days ×  x months = 1 month × 120 days

30x = 120

Then, divide both sides by 30 to solve for the value of x:

[tex]\large\sf{\frac{30x}{30}\:=\:\frac{120}{30}}[/tex]

x = 4

Therefore, there are 4 months in 120 days, making Option C as the correct answer.

Answer:

   The decimal point moves 4 places to the right

Step-by-step explanation:

Take a simple case using the whole number 3.

  3.    —   whole number we're starting with

  3.×10^4 = 3.×10,000 = 30,000.   —   multiplied by 10^4

The decimal point moves 4 places to the right.

_____

Additional comment

Multiplying be a positive power of 10 moves the decimal point a number of places equal to that power. Effectively, the number of zeros added on the right is equal to the power of 10. Above, you will notice multiplying by 10^4 added 4 zeros to the right of the number.

Answer:

  (c)  g(x) = (x/4)^2

Step-by-step explanation:

The graph of f(x) is expanded horizontally by a factor of 4. That means ...

  g(x) = f(x/4) . . . . transformation for horizontal expansion by 4

  g(x) = (x/4)^2

Answer:

a) 16-x=x+4

add x to both sides

16=2x+4

subtract 4 from both sides

12=2x

divide both sides by 2

x=6

b) (8-x)-5=2

add 5 to both sides

8-x=7

add x to both sides

8=7+x

subtract 7 from both sides

x=1

c) 4+x=x+4

subtract 4 from both sides

x=x

x belongs to all real numbers.

Answer:

A) 16-x=x+4

Answer:

i think ur on the right path

Step-by-step explanation:

if it is looking for the percent it would be 23%

Answer:

[tex]i)a + 2b = 2 + 2(3) = 2 + 6 = 8 \\ ii)a + b + c = 2 + 3 + 3 = 2 + 6 = 8[/tex]

Answer:

a = 2, b = 3 and c = 3

a + 2b

2 + 2(3) = 2 + 6 = 8

a + b + c

2 + 3 + 3 = 8

Thus, The answer of i.) is 8 and ii.) is 8

Answer:

12

Step-by-step explanation:

Answer:

12

Step-by-step explanation:

Answer:

12

Step-by-step explanation:

This is easy. Select different values for x to find y values.

For example, let x = 0.

y = 8x + 12

y = 8(0) + 12

y = 0 + 12

y = 12

On your table, you have x = 0 and y = 12.

Do the same using other values of x.

Answer:

Solve equation [2] for the variable y

[2] y = -2x + 1

// Plug this in for variable y in equation [1]

[1] (-2x+1) + 4x = -3

[1] 2x = -4

// Solve equation [1] for the variable x

[1] 2x = - 4

[1] x = - 2

// By now we know this much :

y = -2x+1

x = -2

// Use the x value to solve for y

y = -2(-2)+1 = 5

Solution :

{y,x} = {5,-2}

Answer:

x-5 = 20

x = 25

Step-by-step explanation:

If it's five less than a number and it equals 20, you would add 20 to 5 and get 25, but to make it as an equation, you would do x - 5 = 20.
