2y - 3.5 = 6.5

Answer:

Step-by-step explanation:

Number of days = y

Number of weeks = x

1 week = 7days

Formula = 7x = y

13 weeks = 7(13) = 91 days

29 weeks = 7(29) = 203 days

7.5 weeks = 7(7.5) = 52.5 days

Answer:

-7/(x-5) - 3

Step-by-step explanation:

First off, to reflect an equation in the y axis, just multiply by -1. Now that it is reflected, to stretch an equation by a factor of 7, multiply it by 7. Now we have -7/x.

Then, to move an equation down by 3 units, simply subtract it by 3. Now we have -7/x - 3.

Lastly, since you want to translate it 5 units to the left, you want the equation to be undefined at x = 5 (because originally it is undefined at x = 0). To do that, set the denominator to x - 5. We arrive at our answer: -7/(x-5) - 3.

Using translation concepts, it is found that the new definition for the function is:

[tex]g(x) = -\frac{7}{x - 5} - 3[/tex]

----------------------------

The parent function is:

[tex]f(x) = \frac{1}{x}[/tex]

[tex]g(x) = 7 \times \frac{1}{x} = \frac{7}{x}[/tex]

[tex]g(-x) = \frac{7}{-x} = -\frac{7}{x}[/tex]

[tex]g(x) = -\frac{7}{x - 5}[/tex]

[tex]g(x) = -\frac{7}{x - 5} - 3[/tex]

The answer is C 2^3

hope this helps!!!

Answer:

2^3

Step-by-step explanation:

Ok, let's jump right in!

Multiply 2^6 by 2^−3 by adding the exponents.

Use the power rule a^m a^n = a^m+n to combine exponents. Therefore, we get:

2^ 6-3

Subtract 3 from 6.

2^3

TIP: For next time remember that when you have to multiply exponents you that have the same base number you really just have to add the exponents.

Answer:

Let's name the angle right close to 51 as c.

c = 180°-51° since angles on a straight line is equal to 180°.

so c= 129°

so x = 129° since it corresponds to c

Answer:

Step-by-step explanation:

Notice that the line that the variable x is on is equal to 180 degrees. Because the angle that it is next to is equal to 51 degrees, you subtract 180 from 51:

180-51=129

The final answer to this problem is 129 degrees.

Answer:

62.4

Step-by-step explanation:

1. 1.3x+37.44=1.9x

2. 1.3x+37.44-1.3x=1.9x-1.3x

0.6x=37.44

3. x=37.44/0.6=62.4

The weight of 1 cubic foot of water is 62.4 lb.

Representing Equation with variable on both sides

Let 'x' pounds be the weight of 1 cubic foot of water.

We know one aquarium contains 1.3 cubic feet of water. So, the weight of 1.3 cubic feet of water = 1.3x

The other aquarium contains 1.9 cubic feet of water. So, the weight of 1.9 cubic feet of water = 1.9x

It is given in the question that the water in the larger aquarium weighs 37.44 pounds more than the water in the smaller aquarium.

The equation would be

1.9x  =  1.3x + 37.44

The above equation quality the condition of variable on both sides.

To find out the weight of 1 cubic foot of water, we will solve the above equation to find the value of x.

1.9x  =  1.3x + 37.44

1.9x - 1.3x = 37.44

0.6x  =  37.44

x = 37.44/0.6

x  =  62.4

So, the weight of 1 cubic foot of water is 62.4 lb.

Local Min and Local Max

Step-by-step explanation:

Since our end behavior of our graph is goes on to infinity and negative infinity, we know that we will not have an absolute min or max. However, we will have relative/local min and max.

The local min and max are mins and maxes relative to the surrounding points. We see that our local min would happen around x ≈ 0.75 and our local max will happen at x ≈ -1.9.

Answer:

Ratio of length of cell A to cell B is 20 : 1

Step-by-step explanation:

Length of cell A = [tex]8\times 10^{-6}[/tex] m

Length of cell B = 0.0000004 m

Convert the length of cell B into scientific notation.

Length of cell B = [tex]4.0\times 10^{-7}[/tex]

Now the ratio of the lengths of cell A and cell B = [tex]\frac{8.0\times 10^{-6}}{4.0\times 10^{-7}}[/tex]

                                                                                = [tex]2\times 10^{7-6}[/tex]

                                                                                = 20

Therefore, ratio of length of cell A to cell B is 20 : 1
