One way to determine if you have a closed set is to actually find the open set. The closed set then includes all the numbers that are not included in the open set. For example, for the open set x < 3, the closed set is x >= 3. This closed set includes the limit or boundary of 3

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a,b and c integers and a&gt;1
Pavel [41]

Answer:

4(5x + 6)

Step-by-step explanation:

To start, let's expand things out, as we cannot learn anything from this form. We get 30x + 20 - 10x + 4, or 20x + 24. To find the GCD (Greatest Common Divisor), we take the terms and try to find the number (or term) that divides them. It must be a constant, because of the 24, and 4 goes into 20 and 24. So, our final answer is 4(5x + 6).

What is the equation of the line with slope of ½ , and which passes through the point <br> (4, - 5)?
Cerrena [4.2K]

Answer:

y = 1/2x - 7

Step-by-step explanation:

y = mx + b

m (slope) = 1/2

x = 4

y = -5

<em>substitute</em>

-5 = 1/2 * 4 + b

-5 = 2 + b

-5 -2 = b

-7 = b

y = mx + b

y = 1/2x -7

Find the ratio in which y-axis divides the line segment joining the points A(5, -6), and B (-1, -4). Also find the coordinates o
lora16 [44]

Answer:

Something like this

Step-by-step explanation:

distance √(-1 - 5)² + (-6 - -4)² = √36 + 4 = √40 = 6.32

slope = 2/-6 = -1/3

distance (-1,-4) to (0, -4.63)

√(-1 - 0)² + (-4 - -4.63...)² = √1.4 = 1.18

6.32 - 1.18 = 5.14

1.18 : 5.14
