The slope-intercept equation is y=mx+b.
The slope formula is 
Our three points are (5,5), (-5,-7) and (0,-1)
Using our slope formula our slope becomes 
Then, if we use one of our points (pick whichever you want, although (0,1) is the easiest) to solve the equation. So, 
. When we solve for x and y, we get -1=0+b, or b=-1.
When we plug that back into the equation, we get.

Answer:
39
Step-by-step explanation:
Yield goes down 1 lb for each tree over 23 per acre, so the yield per tree as a function of x trees per acre is ...
yield per tree = 55 -(x -23) = 78 -x . . . . . pounds of cherries
To get the yield per acre, we multiply the number of trees per acre by the yield per tree:
lb/acre = (x tree/acre)((78 -x) lb/tree) = x(78 -x)
This is a quadratic function that opens downward and has zeros at x=0 and x=78. The vertex (maximum) is on the line of symmetry, halfway between the zeros. The yield per acre will be a maximum when ...
x = (0 +78)/2 = 39 . . . . trees per acre
39 trees should be planted per acre to maximize yield per acre.
Factoring is the process of simplifying an equation into its original form. For this linear equation:
1. Get this common factor with the two terms. As what we can observe, 3 is the factor of both terms.
2. Thus, to factor the binomial, we write: 3(5x + 2)
Answer:
50.2cm
Step-by-step explanation:
16/sin(65)=17.65 (2 of those)
16/tan(65)=7.46 (base)
17.65+17.65+7.46=50.23
