In the first week of​ July, a record 1,060 people went to the local swimming pool. In the second​ week, 100 fewer people went to the pool than in the first week. In the third​ week, 140 more people went to the pool than in the second week. In the fourth​ week, 252 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four​ weeks?

Answers

(Can I have Brainlist?)

Answer:

10%

Step-by-step explanation:

The following information can be gotten from the question regarding the number of people that went to the swimming pool are:

First week of July = 1020

Second week = 1020 - 100 = 920

Third week = 920 + 130 = 1050

Fourth week = 1050 - 132 = 918

The percentage decrease over the four weeks will be:

= (1020 - 918)/1020 × 100

= 102/1020 × 100

= 10%

A) y = −2x − 9/2
B) y=−2x+12
C) y = −2x + 7/2

Answers

i think you had a problem in number B which it's suppose to be 1/2 so the correct answer is B

Step-by-step explanation:

.

The equation of this line, y − 5/2 = −2 (x+1) written in slope-intercept form, is y = -2x + 1/2.

What is a line?

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

The equation of a line in slope intercept form,

y − 5/2 = −2 (x+1)

Simplify the above equation,

y - 5 / 2 = -2x - 2

y = -2x - 2 + 5/2

y = -4x - 4 + 5 / 2

2y = -4x + 1 or y = -2x + 1/2

Find three consecutive odd integers such that three times the greatest is 7 less than the
sum of the smallest and middle integer.

Answers

Consecutive odd integers are odd integers that have a difference of 2

The consecutive integers are -17, -15 and -13

How to determine the integers

Let the integers be x, y and z (from least to greatest)

So, we have:

[tex]3z =x + y - 7[/tex]

Also, we have:

[tex]y = x + 2[/tex]

[tex]z = x + 4[/tex]

So, we have:

[tex]3z =x + y - 7[/tex]

[tex]3(x + 4) = x + x + 2 - 7[/tex]

Open the bracket

[tex]3x + 12 = x + x + 2 - 7[/tex]

Collect like terms

[tex]3x -x -x = 2 - 7-12[/tex]

[tex]x = -17[/tex]

Hence, the consecutive integers are -17, -15 and -13

Kiara had the following car expenses last year: $3060 in car payments; $94 for license
and registration: $128 in tax; $1080 for insurance; $290 for parking; $398 for wear and
tear, $1520 for maintenance; and $930 for gas. If she drove 12,500 miles last year, what
was her average cost per mile?

Answers

Average cost per mile is $0.6

How to calculate the average cost per mile?

To calculate the average cost per mile that Kiara had to pay, we perform the following operations:

We add up all the payments Kiara made related to her car.

$3,060 + $94 + $128 + $1,080 + $290 + $398 + $1,520 + $930 = $7,500

Later we divide the total value, in the number of miles traveled by Kiara

$7,500 ÷ 12,500 miles = 0.6

What can be concluded about the line represented in the table? Check all that apply.
X-6,2,8
Y-7,-3,0
The slope is 2.
The slope is 1/2.
The y intercept is 4.
The y intercept is 8
The points (-2,-5) and (8,0) are also on the line
The points (-5,-2) and (1,10) are also in the line.

Answers

Answer:

The slope is 1/2The points (-2,-5) and (8,0) are also on the line

Step-by-step explanation:

According to the table there are ordered pairs:

(-6, - 7), (2, - 3), (8, 0)

Find the slope using two points:

m = (- 3 - (-7)) / (2 - (-6)) = 4/8 = 1/2

Use one point to complete the equation:

y - (-7) = 1/2(x - (-6))y + 7 = 1/2x + 3y = 1/2x - 4

So the slope is 1/2 and the y-intercept is (0, - 4)

Verify the points (-2, -5), (- 5, -2), (1, 10):

-5 = 1/2(-2) - 4 ⇒ - 5 = - 1 - 4 ⇒ - 5 = - 5, yes-2 = 1/2(-5) - 4 ⇒ - 2 = - 2.5 - 4 ⇒ - 2 = - 6.5, no10 = 1/2*1 - 4 ⇒ 10 = 0.5 - 4 ⇒ 10 = - 3.5, no

Now, correct answer choices are:

The slope is 1/2The points (-2,-5) and (8,0) are also on the line
