Answer:

The correct answer should be B: y = -3x + 2.

Since the line crosses the y axis at 2, your y-intercept should be 2. Using rise over run you can compare the equations to the graph. If you convert 3x to a fraction, it would be 3/1x. Since the line is going down 3 and the rise of the y = -3x + 2 is -3, that part is correct. The line also moves over 1 unit, so the run is 1, therefore the correct slope would be -3 or -3/1. Now if you combine what you have it should be y = -3x - 2, which is the same equation as B.

Zinfandel is a popular red wine varietal produced almost exclusively in California. It is rather controversial among wine connoisseurs because its alcohol content varies quite substantially from one producer to another. In May 2013, the author went to a certain website, randomly selected 10 zinfandels from among the 325 available, and obtained the following values of alcohol content (%). 14.9 14.5 16.2 14.3 15.9 13.7 16.2 14.6 13.9 15.1A. Calculate the interpret several measures of center.B. Calculate the sample variance using the defining formula.

B. Initially the pipe leaks at 17 gallons per year.

C. Initially the pipe leaks 17 gallons.

D. Initially the pipe leaks at 4 gallons per minute.

E. Initially the pipe leaks 4 gallons.

F. Initially the pipe leaks at 17 gallons per minute.

Answer: F. Initially the pipe leaks at 17 gallons per minute.

Step-by-step explanation:

Given the equation below:

R = 17 + 4t

Where R is the rate of leakage in gallons per minute,

And t is the age of pipe in years.

The rate of leakage at time t = 0 ( initial rate of leakage )

R(0)= 17 + 4(0)

R(0)= 17 gallons per minute.

Therefore the initial rate of leakage is 17gallons per minute

The constant 17 in the function R = 17 + 4t represents the initial rate of water leakage from the pipe when it is brand new. The correct answer is option C. Initially the pipe leaks 17 gallons.

The constant 17 in the function R = 17 + 4t represents the initial rate of water leakage from the pipe when it is brand new. This means that **option C. Initially the pipe leaks 17 gallons** is the correct answer.

B. r > 1 7/8

C. r ≥ 1 1/8

D. r > 1 1/8

(The fractions are mixed numbers!!!!)

**Answer:**

the answer is C

**Step-by-step explanation:**

this is because he needs at least 1 1/2, it's already rained 3/8 inches, so to simplify the equation change 1 1/2 to 1 4/8 which is still equivalent to 1 1/2, then subtract 3/8 from 1 4/8 which will give you 1 1/8. now here is where it gets kind of tricky, both C and D seem to have 1 1/2, but the difference between them is the symbols > and ≥ are CRUCIAL!!!! (">" means that the number at the left is greater than the number at the right while "≥" means that the number at the left is greater than OR EQUAL TO the number at the right) so as you can see you also need to pay attention to what the text says, because it is mention quote on quote "Hector waters his lawn if it does not rain at least 1 1/2 inches each week," this means that if it's not at least (in other words the same as or more) 1 1/2 inches of rain a week, he will water his plants

The **distance **between the **midpoints **of the first **segment **and the third **segment **is __2k/3__. Hence, __option A__ is the right choice.

The **mid-point** of a **line segment** is the **point **from which the **distance **to both ends of the **line segment** is **equal**.

In the question, we are given a **line segment** of **length **k units, which is divided into 3 equal parts.

We are asked to find the **distance **between the **midpoints **of the first and third **segments**.

Firstly, we divide the **line segment** at **points **k/3 and 2k/3, to get three **equal **parts of **lengths **k/3 each.

Now, the **mid-point** of the first **segment **= (0 + k/3)/2 = k/6.

The **mid-point** of the third **segment **= (2k/3 + k)/2 = 5k/6

Therefore, the **distance **between the **midpoints **of the first **segment **and the third **segment **is (5k/6 - k/6) = 4k/6 = __2k/3__. Hence, __option A__ is the right choice.

Line segment of length k is divided into 3 equal parts.

so first segment is 0-k/3 and third segment is 2/3k-k

so mid-pt of 1st = k/6 and 3rd = 5/6k

so the distance in between = 5/6k-k/6 = 4/6k = 2/3k

ans is A

This is written in slope-intercept form; y = mx + b

m = slope

b = y-intetcept

In the equation we are given;

m = -3

b = -2

Therefore, the y-intercept is -2

Best of Luck!

**Answer:**

**-2**

**Step-by-step explanation:**

__ y = mx + b__is how slope intercept form is written. The "mx" is the slope while the "b" is the y-intercept. In the equation y = -3x -2, we can see that -2 is the y-intercept because it is the value of "b".

The **cost **of 1 hot dog is** $1.75 **and the cost of 1 hamburger is **$2.**

Let x be the cost of one hot dog and y be the value of one hamburger. we will set up a **system **of **linear equations **to solve for x and y:

From the first statement, we recognize that:

7x + 2y = 16.25 ----(1)

From the second statement, we know that:

2x + 7y = 17.50 ----(2)

We will use both **substitution **or elimination method to solve this system of equations. let's use elimination method right here. we are able to multiply equation (1) through 7 and equation (2) by 2 to eliminate y:

49x + 14y = 113.75 ----(3)

4x + 14y = 35 ----(4)

**Subtracting **equation (4) from equation (3), we get:

45x = 78.75

Dividing each sides by using 45, we get:

x = 1.75

Substituting x = 1.75 into **equation **(1), we can solve for y:

7(1.75) + 2y = 16.25

12.25 + 2y = 16.25

2y = 4

y = 2

Consequently, the cost of 1 hot dog is **$1.75 **and the cost of 1 hamburger is** $2.**

Answer:3813

Step-by-step explanation:

First, turn the discount percentage to a decimal

18%= .18

Multiply the decimal by the original price

.18 x 4650= 837

Subtract that amount from the original price to get the discount

4650-837= 3813
