therefore the M (slope) is 2.5

Answer:

y = 2.5x + 3

Step-by-step explanation:

y2 - y1/x2 - x1 = slope

5.5 - 3 = 2.5

2 - 1 = 1

2.5/1 = 2.5

if cot a =5/12 then find the value of cosec A​

Answers

Answer:

cosec A = 13/12

Step-by-step explanation:

Mathematically, we want to find the value of cosec A

sides 5,12 and 13 represent a Pythagorean triple. This means the last side of the right-triangle that contains 5 and 12 is 13

cot is the ratio of the adjacent to the opposite

Hence ; 5 represents the adjacent while 12 represents the opposite

cosec is the inverse of sine which is the hypotenuse to the opposite ratio

So, we have ;

cosec A = 13/12

The perimeter of a triangle is 27. Each side of the triangle has length 2x-3. What is the value of x?

Answers

Answer:

x=6

Step-by-step explanation:

To find the perimeter of the triangle you need to add up all the sides, so if all the sides are 2x-3 the equation will look like this;

2x-3+2x-3+2x-3=27

which when combining like terms will leave it to be;

6x-9=27

Than move all the factors besides x over to the right side;

6x-9+9=27+9

6x = 36

6x/6 = 36/6

x = 6

so your answer will be x=6

Answers

Answer:

Area = 100m²

Step-by-step explanation:

Given :

Height of triangle = 10 m

Length of base = 2 * height = 2 * 10 = 20 m

Area of right angle triangle :

1/2 * base * height

Area = 1/2 * 20 * 10

Area = 0.5 * 10 * 20

I need the answer for Number six

Answers

Step-by-step explanation:

Although I can't give you a written answer, here's how you do it.

For y = -x + 7,  we know 7 is our y coordinate, so place a point on 7 on the y axis.

-x is equal to -1/1, so when graphing the line, go down 1 over 1 and place your point. Continue until you reach the edge of the graph.

For 5x + 5y = 10, subtract 5x from the left side of the equation. This will leave you with:

5y = -5x + 10. Divide every term by 5, leaving you with y = -x + 2. Your teacher may want you to phrase this as y = 2 - x.  2 is your y coordinate, and once again -x is -1/1. Start at 2 and go down 1 over 1 on the graph.
