what is the area of the triangle

Answers

Answer 1

Answer:

Step-by-step explanation:

There are several ways to find area of triangle from vertex coordinates, the easiest is: (x₁*(y₂-y₃) + x₂*(y₃-y₁) + x₃*(y₁-y₂)) / 2

Area = ((-1)*(-6 - -6) + (-6)*(-6 - 2) + (3)*(2 - -6)) / 2

= (0 + 48 + 24) / 2

= 72/2

= 36

What is the equation of this line written in slope-intercept form?
y − 5/2 = −2(x+1)

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

The members of the city cultural center have decided to put on a play once a night for a
week. Their auditorium holds 600 people. By selling tickets, the members would like to raise $3,300
every night to cover all expenses. Let d represent the number of adult tickets sold at $7.50. Lets
represent the number of student tickets sold at $4.50 each. If all 600 seats are filled for a
performance, how many of each type of ticket must have been sold for the members to raise exactly
$3,300? At one performance there were two times as many student tickets sold as adult tickets. If
there were 300 tickets sold at that performance, how much below the goal of $3,300 did ticket sales
fall?

Answers

To answer the first question, we have these two equations:

x + y = 500 and 7.5x + 4.5y = 2550

We can use substitution to solve for x and then plug it back into any equation and find y.

y = 500 - x

7.5x + 4.5 (500 - x) = 2550

7.5x + 2250 - 4.5x = 2550

3x = 300

x = 100 adults

100 + y = 500 → y = 400 students

To answer your second question, we have two new equations:

2x = y (This may be confusing, but since there were more student tickets sold, it is the larger number.)
x + y = 300

We can rewrite the first equation and add them together:

2x - y = 0
x + y = 300

3x = 300

x = 100 adults

100 + y = 300 y = 200 students

The money earned from these 300 people is 100 * 7.5 + 200 * 4.5 = 750 + 900 = $1650.

$2550 - $1650 = $900

The 300 tickets sold had a $900 fall in ticket sales.

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

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%
