Answer:

The appropriate choice is the 2nd one ...

... Reflection over the y-axis followed by a translation down by 5 units.

Step-by-step explanation:

The transformed figure has the opposite orientation (A'B'C'D' is counterclockwise, whereas ABCD is clockwise), so a reflection is involved. The sgment C'D' is still at the bottom, as is CD, so the reflection must be across a vertical line.

In the attached, the light-blue figure A''B''C''D'' shows the reflection of ABCD across the y-axis. It is easy to see that figure A'B'C'D' is a translation of that 5 units downward.

The appropriate choice is the 2nd one ...

... Reflection over the y-axis followed by a translation down by 5 units.

Answer:

k=2

Step-by-step explanation:

2x-8y+k/2=0

puting the values of x and y

2*2-8*1+k/2=0

4-8+k/2=0

-4+k/2=0

k/2=4

sing changes if side changed

k=4/2

k=2

We first substituted the X and Y in the equation, so 2 instead of X and 1 instead of Y.

Then I moved the K to make it the subject of the equation by algebra which gave me a -K, but I want k not negative k so I multiplied everything by -1 because, -1 × -1= +1 so K=2.

memorize this formula so you always know slope for 2 points given.

y is the second number in parentheses.

whichever you choose as y2 or y1, the x values will match those numbers as well.

(y2-y1) = (1-5)

Answer:

$32.50

Step-by-step explanation:

The equation for simple interest is

Simple Interest=P×r×n

where:

P=Principal amount

r=Annual interest rate

n=Term of loan, in years

​so

P=200

r=0.0325

n=5

so 200*0.0325*5=32.5

Your answer would be 2/10

Step-by-step explanation:

So first do -1/4 + 3/8 which is 0.125 in decimal form if you prefer to do decimal way

Next: 5/8 is 0.625

Finally: 0.125 divided by 0.625 is 0.2 which in fraction form is 2/10

Answer:

7.4

Step-by-step explanation i took the test

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

x - x/2 - 6.8 = -3.1

x = 7.4

The temperature at the beginning of the day was 7.4°F.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The temperature at the beginning of the day = x

The temperature during the day = x/2

The temperature after the sun goes down = 6.8°F

The temperature at the end of the day = -3.1°F

Now,

We can write an expression as,

x - x/2 - 6.8 = -3.1

x - x/2 = -3.1 + 6.8
x/2 = 3.7

x = 7.4°F

Thus,

The temperature at the beginning of the day was 7.4°F.

Answer:

D 36

Step-by-step explanation:

Write the information algebraically

c = 3a

c + a = 48

c = children, a = adults

In the second sentence (in bold), we can replace c with 3a

c + a = 48 → 3a + a = 48

Simplify

3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)

We can then substitute or plug in a = 12 into the original equation:

c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)

Answer:

no

Step-by-step explanation:

1. Pi is an irrational number, and irrational numbers CANNOT be written as a fraction. Pi is a non-repeating, non-terminating decimal number.

2. While 22/7 and 3.14 is often used as a value for pi, these are just approximations, so they're not completely exact.

Answer:

C

Step-by-step explanation:

The given function h (x) = [x] + 4 as the greatest integer function which is the correct answer would be option (B).

The greatest integer function takes the greatest integer that is less than or equal to a specified value. The biggest integer less than or equal to a number x is expressed as ⌊x⌋. It will round off the input number to the nearest integer that is less than or equal to the number itself.

Mathematically, the greatest integer function ⌊x⌋ can be defined as follows:

⌊x⌋ = n, where n ≤ x < n + 1 and 'n' is an integer.

According to the given question,

The function is below as

⇒ h (x) = [x] + 4

Here ⌊x⌋ = 4, where 4 ≤ x < 4 + 1 and '4' is an integer.

The given function as the greatest integer function takes the greatest integer that is less than or equal to a value of 4.

Hence, the correct answer would be an option (B).
