1) take away the brackets and distribute the plus:
13x + 9y + 38x + 33y

2) add the like terms
13x + 38x + 9y + 33y
= 51x + 42y

A function f(x) is graphed on the coordinate plane.
Sidana [21]

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:

  • y = - 4x - 2

The price of an electronic puzzle was reduced be $7
Nimfa-mama [501]

Answer:

Step-by-step explanation:

total price was reduced by $ 7

let x = the total price........ x - 7

he bought 10.....and it cost him $ 130

10(x - 7) = 130

10x - 70 = 130

10x = 130 + 70

10x = 200

x = 200/10

x = 20 <====== original price
