answer is C 1410.01 mark as brainliest

If x = -6

Plug in -6 for x

f(x) = 3x + 4

f(-6) = 3(-6) + 4

Remember to follow PEMDAS. First, multiply

3 x -6 = -18

Finally, add

-18 + 4 = -14

f(-6) = -14

f(-6) = -14 is your answer

The attempt to solve the provided system of equations by elimination encountered a misunderstanding in the manipulation of the equations. A straightforward correction highlighted the importance of accurately aligning coefficients before attempting to eliminate a variable, underscoring the necessity of precise calculations in solving such problems.

To solve the given system of equations by elimination, we start with the system:

Our goal is to eliminate one of the variables, either x or y. To do this efficiently, we aim to make the coefficients of either x or y the same or exact opposites. In this case, we can easily adjust the second equation to align the coefficients of y by multiplying the entire equation by a suitable number.

Multiply the first equation by 1 (effectively keeping it the same) and the second equation by 7/4 to align the y coefficients:

However, there seems to be a misunderstanding in the calculation or transcription of the equations provided. Instead, let's correct the approach based on the equations listed in the inquiry.

Looking at the original system provided:

We see an opportunity to simplify the first equation by dividing everything by -7:

Now, to proceed with elimination effectively, aligning coefficients or a straightforward substitution should be re-evaluated, given the error in initial steps noted. Let's correct it:

Notice the instructional error in application; hence, a direct solution via the provided method is not feasible without the correct system alignment or revised equations. When solving similar problems, getting coefficients to align through multiplication or division is key before adding or subtracting equations to eliminate a variable.

Elimination becomes difficult with inaccurate steps, so it's crucial to double-check each phase of your work.

The occupation staged by American Indians in 1969 was in order to to raise awareness about unfair treatment.

American Indians in 1969:

The reason they did this was to draw attention to the injustices they were subjected to and the unfair treatment of American Indian tribes by the U.S. government. This led to the federal government giving more land to them.

A flying disc is assumed to be in the shape of a circle. Since we know it is in the shape of a circle, we can use the formula for circumference of a circle.

The formula for circumference of a circle is d * pi, where d represents the diameter of the circle and pi is the representation of 3.14.

You can find the circumference of a circle by multiplying the diameter by pi, and since the question gives us the diameter of the flying disc we can substitute in 9 inches for the diameter to solve for the circumference.

diameter * pi

(9 inches) * ([tex]\pi[/tex]) = 28.2743...

The question wants the final answer to be rounded to the nearest tenth, so rounding 28.2743... to the nearest tenth would make it into 28.27.

The answer to this problem is the circumference of the disc is 28.27 inches.

Answer:

60 mph

Step-by-step explanation:

Let distance travelled by both the cars equal to d.

Also assume speed of Car A as x and speed of Car B as y

Then using distance formula,

d = 2x

Similarly for car B, d = 1.5 y

Also given that

speed of car B = speed of car A +15

y =x+15

Hence we have 2 x = 1.5 y  Or x =0.75 y

Substitute in y =x+15 :  y =0.75y+15

0.25y = 15

y = 15/0.25 = 60 mph

Speed of car B = 60 mph

To cover costs and achieve a $90 profit, each collar should be sold for $175 divided by the number made.

To determine the selling price for each dog collar, we need to consider both the cost of materials and the desired profit.

1. **Calculate total cost**:

  - Cost of materials: $85

  - Desired profit: $90

  Total cost = Cost of materials + Desired profit

             = $85 + $90

             = $175

2. **Determine number of collars**:

  Since you anticipate selling all the collars, the total profit should cover the cost of materials and the desired profit.

3. **Calculate selling price per collar**:

  Divide the total cost by the number of collars to determine the selling price for each collar.

[tex]\[ \text{Selling price per collar} = \frac{\text{Total cost}}{\text{Number of collars}} \][/tex]

Substitute the values:

[tex]\[ \text{Selling price per collar} = \frac{\$175}{\text{Number of collars}} \][/tex]

Without knowing the exact number of collars, we can't determine the exact selling price per collar. However, if you know the number of collars you're making, you can use this formula to find the selling price for each collar.

The commutative property is illustrated by option D, where adding sprite and orange juice to a punch mixture shows that the order in which the ingredients are mixed does not affect the final product.

The commutative property primarily relates to mathematical operations like addition and multiplication, where changing the order of the numbers does not change the result. For example, in addition, 4 + 5 is the same as 5 + 4. Applying this concept to the options provided, the pair that is an example of the commutative property is adding sprite and orange juice to a punch mixture (Option D). Whether you add sprite to the orange juice or orange juice to the sprite, the resulting punch mixture remains the same.

x^2 + y^2 - 2x + 8y - 47 = 0

x^2 + y^2 - 2x + 8y = 47

(x^2 - 2x) + (y^2 + 8y) = 47

(x^2 - 2(1)x) + (y^2 + 2(4)y) = 47

(x^2 - 2(1)x + 1^2) + (y^2 + 2(4)y + 4^2) = 47 + 1^2 + 4^2

(x - 1)^2 + (y + 4)^2 = 64 = 8^2

Refillable mug:

Fixed cost is $3.50 including 16 oz of coffee

Each additional 16 oz of coffee cost $0.50

Disposable cup:

Cost is $1.00 per 12 oz of coffee

We can build up a table showing number of purchases, cost, and amount of coffee for each type of purchase until we see the refillable cup becoming cheaper.

                Refillable Mug              Disposable cup

               Cost     Amount              Cost       Amount

1               3.50        16                    1.00                  12

2              4.00        32                   2.00                24

3              4.50         48                  3.00                 36

4              5.00         64                  4.00                 48

5              5.50         80                  5.00                 60

Notice that with 3 fill ups of the refillable cup, you have bought 48 oz of coffee for $4.50. With the disposable cup, the same 48 oz of coffee represent 4 cups, but at only $4.00, so up to the amount of 48 oz of coffee, you are better off buying the disposable cups.

When you spend $5.00, you can have 64 oz of coffee using the refillable cup or 60 oz of coffee using the disposable cup. When you spend $5.00 and up, then the refillable cup gives you the better price.

Answer: The refillable cup becomes cost effective at 64 oz.
