2 x + y equals negative 9

The correct answer is B. The function has a constant rate of change, decreasing for all x at a rate of 6.

In order to find the rate of change, we have to identify the slope. The slope is always the coefficient of x when in slope intercept form. In this case it is -6, which means it decreases at a rate of 6.

To describe the rate of change of the function \( f(x) = -6x - 7 \), we first need to understand that the rate of change in the context of a function, particularly a linear function, is another term for its slope.

Now, let's recall what the slope of a linear function means. A linear function is of the form \( y = mx + b \), where \( m \) is the slope, and \( b \) is the y-intercept. The slope \( m \) determines how steep the line is, and it represents the change in the y-value (the output of the function) for a unit change in the x-value (the input of the function).

Looking at the given function \( f(x) = -6x - 7 \), we can see it is in the same form as \( y = mx + b \), with the slope \( m = -6 \) and the y-intercept \( b = -7 \).

The slope being -6 means that for every one unit increase in \( x \), the function's value decreases by 6 units. This is a constant rate of change because it does not matter what the value of \( x \) is; the function will always decrease by 6 for every one unit increase in \( x \).

Now, let's examine the given statements:

 A. The function has a varying rate of change when \( x < 7 \).
    - This statement is incorrect because the slope is constant at -6, regardless of the value of \( x \).
 
 B. The function has a constant rate of change, decreasing for all \( x \) at a rate of 6.
    - This statement is correct; it accurately describes the behavior of a linear function with a slope of -6.
 
 C. The function has a varying rate of change when \( x < 6 \).
    - This statement is also incorrect because, once again, the rate of change (slope) is constant for all values of \( x \).
 
 D. The function has a constant rate of change, decreasing for all \( x \) at a rate of 7.
    - This statement is incorrect; the coefficient of \( x \) in the function, which represents the slope, is -6, not -7.

Based on our analysis, the correct answer is:

 B. The function has a constant rate of change, decreasing for all \( x \) at a rate of 6.

Assuming each movement is in a straight​ line, the composition

represents the moves.

Each movement is in a straight line, the composition represents the moves <-5, 1>, <-3, 4>, <1, 4> and <2, 7>.

Given that, a robot travels from position A to B to C to D.

We need to find what composition of rigid motions represents those moves.

Any way of moving all the points in the plane such that

a) the relative distance between points stays the same and

b) the relative position of the points stays the same.

There are four types of rigid motions that we will consider: translation, rotation, reflection, and glide reflection.

In a translation, everything is moved by the same amount and in the same direction. Every translation has a direction and a distance.

Therefore, each movement is in a straight line, the composition represents the moves <-5, 1>, <-3, 4>, <1, 4> and <2, 7>.

The ratio of 16 days to 2 weeks, when converted to the same units and reduced to its simplest form, is 8:7.

To write the comparison of 16 days to 2 weeks as a ratio in the lowest terms, we first need to express both quantities in the same units. There are 7 days in a week, so 2 weeks equal 14 days. The ratio between 16 days and 14 days is therefore 16:14. This ratio can be reduced to lowest terms by dividing both numbers by their greatest common divisor, which is 2. This gives us the reduced ratio of 8:7.

So, the ratio of 16 days to 2 weeks, reduced to lowest terms, is 8:7.

Answer:

Rhonda: 39 hours; Chris: 18 hours.

Step-by-step explanation:

If you subtract the extra 3 hours from the total, you have Chris's hours plus twice Chris's hours adding to 54. That is, Chris worked 54/3 = 18 hours, and Rhonda worked 57-18 = 39 hours = 2·18 +3 hours.

If you insist on equations, you can write two of them:

... r = 2c +3

... r + c = 57

Substitute for r in the second equation:

... (2c +3) +c = 57

... 3c +3 = 57 . . . . . from here down, the explanation above matches this math

... 3c = 54

... c = 54/3 = 18

... r + 18 = 57 . . . . . . substitute for c in the second equation

... r = 57 - 18 = 39

First, change the mixed fraction into improper fraction. Change the whole number into a fraction, and add.

1 8/11 = 11/11 + 8/11 = 19/11

To find the reciprocal, flip the fraction.

The reciprocal of 19/11 is 11/19

hope this helps

Final answer:

The reciprocal of 1 ⁸/₁₁ is 11/19, which is calculated by first converting the mixed number to an improper fraction (19/11) and then flipping the numerator and denominator to get the reciprocal.

Explanation:

To find the reciprocal of 1 ⁸/₁₁ , you first need to convert the mixed number to an improper fraction. To do this, multiply the whole number by the denominator, add the numerator, and then write the result over the original denominator. In this case, 1 ⁸/₁₁ becomes (1×11 + 8)/11, which simplifies to 19/11.

Now, the reciprocal of a fraction is obtained by flipping the numerator and denominator. So the reciprocal of 19/11 is 11/19. Therefore, the reciprocal of 1 ⁸/₁₁ is 11/19.

Understanding the concept of reciprocals is important in mathematics because dividing by a number is the same as multiplying by its reciprocal. In this context, dividing by 1 8/11 is equivalent to multiplying by 11/19.

Isolate the f. Note the equal sign. What you do to one side, you do to the other.

First, subtract 6e from both sides

6e (-6e) - 7f = 8g + h (-6e)

-7f = 8g + h - 6e

Divide -7 from both sides

(-7f)/-7 = (8g + h - 6e)/-7

f = -8/7g + h/-7 + 6/7e

f = -8/7g + h/-7 + 6/7e is your answer

To simplify 7(x-4), distribute 7 over x and -4 to get 7x - 28. This is an application of the distributive property in algebra.

Explanation:

To simplify the expression 7(x-4) using the distributive property, you multiply the number outside the parenthesis, which is 7, by each term inside the parenthesis. The distributive property allows us to remove the parentheses by distributing the multiplication over the subtraction within.

Here is the step-by-step simplification:

Multiply 7 by x, which is 7x.

Multiply 7 by -4, which is -28.

Combine the results to get 7x - 28.

Therefore, 7(x-4) simplifies to 7x - 28.

Answer:

375

Step-by-step explanation:

Did it on Edge

The total distance of the race is 375 miles.

Given data:

To find the total distance of the race, multiply the distance of the loop by the number of times Carlos raced around it.

Total distance = Distance of the loop * Number of times raced

Distance of the loop = 15 miles

Number of times raced = 25

Substituting the values into the formula:

Total distance = 15 miles * 25

On simplifying the equation:

Calculating the product:

Total distance = 375 miles

Hence, the total distance was 375 miles.

after everything you've ran the total would be 9.7 but you'll need to run a total of 13.1 so you still need to run 3.4 miles so you Thursday and Friday you'll run 1.7 each.

so if the original price of the bicycle is $360 and the sale price is 5/6 of that you would multiple $360 by 5/6 which equals 300 now thats NOT your final price you have one more step which is to subtract the sale (money off) the original price 360-60 so the sale price of the bicyle is $300

answer:

$300

step-by-step explanation:

our original price is $360 and we need find 5/6 of 360

our first step is to multiply 360 by 5 which is equal to 1,800

our next step is it divide by 6 which is equal to 300

so our sale price is $300

i think the answer is 214 i am not sure but i think it is

The number you are looking for is 211.

To find the number that meets the given criteria, we need to consider a few steps

1. The number, when rounded to the nearest ten, is 210.

2. The sum of the digits of the number is 4.

First, let's consider the numbers that round to 210 when rounded to the nearest ten. These numbers fall within the range of 205 to 214 (inclusive).

Next, let's identify which of these numbers has digits that sum to 4.

- 205: (2 + 0 + 5 = 7)

- 206: (2 + 0 + 6 = 8)

- 207: (2 + 0 + 7 = 9)

- 208: (2 + 0 + 8 = 10)

- 209: (2 + 0 + 9 = 11)

- 210: (2 + 1 + 0 = 3)

- 211: (2 + 1 + 1 = 4)

- 212: (2 + 1 + 2 = 5)

- 213: (2 + 1 + 3 = 6)

- 214: (2 + 1 + 4 = 7)

From this list, the number 211 is the only number within the range that has digits summing to 4.

We know that the perimeter of a rectangle is:

The long is y

The width is y-5.
