Which of the following correctly represents the set of numbers using interval notation?

Answer:

If you made $33 in 8 hours, then you should divide 8 into 33 to see how much you make per hour. 8÷33= (explaining how to get answer) can 8 go into 3? No. put a zero on top of the first three. Now can 8 go into 33? yes, 4 times, 4×8= 32, so we have 1 left over. add 2 decimals to the number so that it is $33.00, (still that same number just with zeros on the end). So far the answer is $04.??. How many times can 8 go into 10? 1 time with 2 left over, so write the one on top of the .0! Now with 2 left over we have to see how many times 8 can go into 20, 8×2= 16 16+8=24, so it can only go in 2 times without going over 20. Now that we have rounded it up to 2 decimals we don't have to keep going and your answer is

$4.12 times that by 5 and you will get the final answer.

4.12

Answer:

[tex]k=-72[/tex]

Step-by-step explanation:

[tex]38=\frac{1}{8} k+47[/tex]

Switching the sides of the equation isn't required, but it helps to reduce confusion.

[tex]\frac{1}{8}k+47=38[/tex]

Since there is a positive 7, we are going to do the opposite operation, which is addition.

[tex]\frac{1}{8}k+47-47=38\\\text\:\:\:\:\:\:-47\:\:\:\:\:\:\:\:\:-47[/tex]

Simplify

+47 - 47 will cancel each other out, so we are left with:

[tex]\frac{1}{8}k=-9[/tex]

Now, multiply 8 to both sides, since the equation gives us 1 divided 8, so the opposite operation of division is multiplication.

[tex]8\cdot \frac{1}{8}k=8\left(-9\right)[/tex]

On the right side, we have the same thing as [tex]\frac{8}{1} \cdot \frac{1}{8}[/tex], so 8 we can cancel the equation on the right side since they are both the same number.

On the left, we have [tex]8\left(-9\right)[/tex], which is -72.

Therefore, [tex]k=-72[/tex].

Answer:

.

Step-by-step explanation:

Answer:

(-3.2 , 12.3)

(0.7 , 3.6)

Step-by-step explanation:

The rule :

(x, y)→(x−7.5, y+6.8)

For the x - coordinate ; Subtract 7.5

For the y - coordinate `; add 6.8

First input : (4.3, 5.5)

Output :

x = 4.3 - 7.5 = - 3.2

y = 5.5 + 6.8 = 12.3

Output = (4.3, 5.5) →(-3.2 , 12.3)

Second input : (8.2, -3.2)

Output :

x = 8.2 - 7.5 = 0.7

y = - 3.2 + 6.8 = 3.6

Output = (8.2, -3.2)→(0.7 , 3.6)

The outputs obtained are :

(-3.2 , 12.3) and (0.7 , 3.6)

$166.71

Step-by-step explanation:

Answer:

Step-by-step explanation:

The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides. The problem concerns a polygon with six sides, so we will let n = 6. The sum of the interior angles in this polygon would be 180(6 – 2) = 180(4) = 720. The angle on the bottom left is a right angle because of the square indicator. We know that this is 90 degrees. If we take the sum of the angles that we know we get 593. 720 - 593 = 127. x = 127.

Answer:

x=127

Step-by-step explanation:

take 180(n-2) where n=6, and you get 180(6-2) which simplified is 180(4) = 720. The sum of all the other angles is 593. subtract 593 from 720 (720-593=127). 127 is the angle of x.

all the steps laid out:

1. 180(n-2)

2. n=6

3. 180(6-2)

4. 180(4) = 720

5. 126 + 112 + 155 + 110 + 90 = 593

6. 720 - 593 = 127

7. x=127

Answer:

n = 1

Step-by-step explanation:

n - 6 = 5(n-2)

n - 6 = 5n - 10

-6 +10 = 5n - n

4 = 4n

n = 4/4

Answer:

x=24

Step-by-step explanation:

8x + 4(4x - 3) = 4(6x + 4) - 4

8x + 16x - 12 = 24x + 16 - 4

24x - 12 = 24x + 12

24x = 24x + 12 + 12

24x = 24x + 24

24x/24x = 24

x = 24

Answer:

0

Step-by-step explanation:

8x + 4(4x - 3) = 4(6x + 4) - 4

8x + 16x - 12 = 24x + 16 - 4

24x - 12 =  24x + 12

-24x                  -24x

      -12 = 12

      +12   +12

        0 = 24

Answer:

D.

Step-by-step explanation:

Your graph of f(x)= [tex]x^2[/tex] is the parent function. What you need to know for this graph what the stretch or compression is and what the flip is. When you flip somehting over the x-axis, which is g(x), your [tex]x^2[/tex] is negative. Also, since your graph gets skinnier, the number before the x would be a whole number, with no fractions. The only answer that fulfills this is answer choice D.

Answer:

perimeters equal 7/6 and area equals 49/36

Step-by-step explanation:

The ratio of perimeters is equal to the scale factor. To find the scale factor setup a fraction, red/blue since that's what it says in the directions.

The ratio of areas is the scale factor squared.

Step-by-step explanation:

Step-by-step explanation:

y=−x+2

Explanation:

Alright, so this is a two-part question. First we need to find the slope, then we need to find the y-intercept. Finally we plug all this into the slope intercept equation y=mx+b

The slope is commonly referred to as m=riserun this can also be expressed as m=y2−y1x2−x1 by using the change in y and the change in x.

m=5−8−3−(−6)

m=−33

m=−1

Alright, now lets find the y-intercept by using that slope. If we plug that slope into the base formula we get y=−x+b. Since we already know one point, lets put (−3,5) into that equation and solve for b.

5=−(−3)+b

5−3=3+b−3

2=b

Now is if plug out b into out equation, we get a finally answer of y=−x+2

Even though we're done, lets check it by putting in the other point.

8=−(−6)+2

8−6=6+2−6
