3y = -x + 3

y= (-1/3)x + 1

perpendicular: 3

y + 1 = 3(x - 6)
y + 1 = 3x - 18

y = 3x - 19

The sum of 444 consecutive integers is 326326326.<br> What is the second number in this sequence?
Nookie1986 [14]

Answer:

82

Step-by-step explanation:

Let's first figure out what the first number is and use that to solve for the next. The problem states that the numbers are consecutive. So the 2nd number word be 1 plus the first.

The sum of 4 consecutive numbers:

1st = x

2nd = x + 1

3rd = x + 2

4th = x + 3

The sum of 4 consecutive number is 326.

1st + 2nd + 3rd + 4th = 326

x + (x + 1) + (x + 2) + (x + 3)  = 326

Combine like terms:

4x + 6 = 326

Then we subtract 6 from both sides to isolate 4x:

4x + 6 - 6 = 326 - 6

4x = 320

Then we divide both sides by 4 to isolate x:

4x/4 = 320/4

x = 80

So the first number is 79

Now to get the second, let's just add 1.

80 + 1 = 81

Let's check if our answer would be correct:

80 + 81 + 82 + 83

= 326

24. Find the slope and y-intercept of the line.<br> Y=7/5x-3
Ad libitum [116K]

Answer:

slope = m = 7/5

y-intercept = b = -3

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

y = 7/5 x - 3

slope = m = 7/5

y-intercept = b = -3

Can someone help with this question

Question # 55

We can see the trend from the given graph. From Monday to Thursday the price kept on decreasing while on Friday it increased. So first the price decreased and then increased.

Therefore, the correct answer to this question is option C. The price decreased at the beginning of the week and then increased at the end of the week.

Question # 56.

The schedule of athlete allows no more than 75 minutes of training. This means the training time is 75 minutes or less. One round of strength training requires 8 minutes. So s rounds of strength training will require 8s minutes. One round of endurance training require 12 minutes, so e rounds of endurance training will require 12e minutes.

The total time of both these trainings can be written as:

8s + 12e

We know that the time can be 75 minutes or lesser. So we can write the inequality as:

8s + 12e ≤ 75

So, option H is the correct answer

Question 57

The given equation is:

2y = - 3(x - 2)

In order to identify the slope we need to write the equation if slope intercept form. When written in slope intercept form, the coefficient of x term is the slope of the line. In order to write in slope intercept form, isolate y on one side as shown below:

2y=-3(x-2) \\  \\ &#10;2y=-3x+6 \\  \\ &#10;y=- \frac{3}{2}x+3

So, the slope of line is -3/2.

Hence option B is the correct answer

Solve for X.<br> - 3x + 2 = -10x + 30
Nataly_w [17]

Answer:

x = 4

Step-by-step explanation:

-3x + 2 = -10x + 30

Add 10x to both sides and you get

7x + 2 = 30

Subtract 2 from both sides and you get

7x = 28

Divide both sides by 7 to get x by itself and you get

x = 4

Reminder whatever you do to one side you have to do to the other side!

Hope this helps!

456 students participate in and switch day the students raise money for charity so that the principle approve the day if you tur
alexandr402 [8]

Answer: The amount of money each student raised = $2

Step-by-step explanation:

Given : In charity

Total students participate= 456

Total collection = $912

Each student brought in the same amount of money , then the amount each student raised = \dfrac{\text{Total collection }}{\text{Total students}}

=\$\dfrac{912}{456}\\\\=\$2

Hence, the amount of money each student raised is $2.
