Answer: y = - 4x + 2
Explanation:
The graph shows a linear function, which is a first degree polynomial, whose form is ax + b.
The rule or fucntion is f(x) = y = ax + b. This form is called the slope-intercept form, because the coefficient a is the slope of the line and b is the y-intercept.
The graph permits you to calculate both parameters.
1) The slope, a is defined in this way:
- a = rise / run = [change in y] / [change in x] = [y₂ -y₁] / [x₂ - x₁]
- you can use the points (0, - 2) and (-1,2):
⇒ a = [ 2 - (-2) ] / [ -1 - 0 ] = 4 / (-1) = - 4
2) b, the y-intercept, is the value of the function, y, when x = 0. In the graph you can see that this is - 2. b = - 2.
3) Substituting the values of a and b in the form y = ax + b, you the rule:

Step-by-step explanation:
Rectangle: 7x6=42
1/2 Circle: 1/2x3x3x
=14.137
42+14.137=56.137
The producy means multiplication so : 6256 ×486=
=3,040,416
Answer:
f = (N² - H)/6
Step-by-step explanation:
Step 1: Write equation
N² = 6f + H
Step 2: Solve for <em>f</em>
- Subtract H on both sides: N² - H = 6f
- Divide both sides by 6: (N² - H)/6 = f
- Rewrite: f = (N² - H)/6
