-5х + Зу = -8
3х - 7y = -3

Answers

Answer:

wrong

Step-by-step explanation:

-5x + 3y, you can’t add those together since they aren’t like numbers

3x - 7y, can’t be done either since again, they aren’t like numbers.

like numbers include the same variable or no variable, which means you cant do -5x + 3y but you can to -5x + 3x. you can add those together since both of the numbers have the variable “x” while 3y and 7y have the same variable “y” therefore those can be added together.

since there isn’t a way to add those, both of those answers are not only wrong, but they’re also in simplest form.

Determine the MEDIAN of the following numbers: 8, 11, 11, 12, 13, 15, 16, 16,
18, 21
15
13
14
21

Answers

Answer:

Step-by-step explanation:

Determining Median is super easy!

1. Order the numbers, in ascending order.

8, 11, 11, 12, 13, 15, 16, 16, 18, 21

2. Cross off one number from both ends until you reach the middle number, whether you're left with one or two.

11, 11, 12, 13, 15, 16, 16, 18

11, 12, 13, 15, 16, 16

12, 13, 15, 16

13, 15

3. Determine the average of these two numbers.

(13 + 15) / 2

28 / 2

The median for this set of data is 14.

P.S. the average only needs to be calculated when left with two numbers, if you are left with only one, that number is your answer!

Hope this helps :)

A sector has an area of 50 ft sq, and a central angle of 45 degrees. Find the radius.

Answers

Answer:

Step-by-step explanation:

45° is 1/8 of a circle, so the area of the sector is 1/8 the area of the circle.

Area of circle = 8*50 = 400 sq ft

πr² = 400

r = √(400/π) = 20/√π ≈ 11.3 ft

Answer:

(5, 8)

Step-by-step explanation:

The circumcenter of a right triangle is the midpoint of the hypotenuse.

O = ((2, 6) +(8, 10))/2 = (2+8, 6+10)/2

O = (5, 8)

The circumcenter is (5, 8).

a. 9 + 4² - (4-2) • 4

9 + 4² - (4-2) • 4 –––Start with (4-2) = 2 (parentheses)

They are used for making the sides of a triangle into a ratio. Sine is opposite of the angle divide by the hypotenuse, cosine is adjacent divided by the hypotenuse, and tangent is the opposite divided by the adjacent. Sine is the y-component, cosine is the x-component, and tangent is the ratio of sine/cosine or can also be considered the slope.
