Answer:

If point A = (4,4) and B = (8,7)

The slope of M would be 3/4.

Step-by-step explanation:

m = y^2 - y^1/x^2 - x^1 = 7 - 4/ 8 - 4 = 3/4. m = 3/4.

y = mx + b

y = 3/4 x + b

4 = (3/4)(4) + b

b = 4 - 3 = 1

The equation of line AB is y = 3/4 x + 1.

I hope this helps and that it is easy to understand and read! :)

Answer: I couldn't find the answer but I did find the formula? Sorry if this doesn't help much :(

Update:

Center at (-3,0)

Radius = 1

Step-by-step explanation:

(x-x1)^2 + (y-y1)^2 = r^2

(x-x2)^2 + (y-y2)^2 = r^2

Answers:

Perimeter = 58.5 centimeters

Area = 163.15 square centimeters

===============================================

Explanations:

To get the perimeter, you add up the three exterior (aka outer) sides. So you add up everything but the length measuring 13 cm, as this segment is not on the outside of the triangle. Imagine this is a parking lot and you want to put fencing around the outer sides. You won't build any fencing to run through the middle of the lot (assuming you don't want to subdivide)

So we add up 15.4, 18 and 25.1 to get 15.4+18+25.1 = 58.5 centimeters. The units stay at centimeters. We don't go to "square centimeters" like we do with the area below.

------------

To get the area of the largest triangle, we multiply the base and height, then divide by 2. The base is always perpendicular to the height

base = 25.1

height = 13

area = base*height/2 = 25.1*13/2 = 163.15 square cm

You write "square" before the "cm" to indicate the proper units for the area. Think of a 1 cm by 1 cm rectangle which has area of 1*1 = 1 square cm. This idea applies to triangles as well because we can subdivide the triangle into smaller squares, or you can move one piece of a triangle to another side to reshape the figure into a rectangle.

Answer:

The average is exactly 26,375 gallons of gas per hour.

How I found this is buy subtracting each numbers like 422,000 - 369,250 = 52,750. 369,250 - 316,500 = 52, 750 and so on. They all ended up being 52,750, but then I realized that they are all 2 hours apart and the question asks of gallons of gas per 1 hour so then I divided 52,750 in half and got my final answer, 26,375.

Step-by-step explanation:

This is how much gas the jet uses per 1 hour

my question doesn't ask me to create a linear model but it asks for gasoline per hour, and it's just like this question with the same graph so if you have the same as me this is the answer.
