Answer:
(0.25x, 0.25y)
Step-by-step explanation:
Since the origin is the center of the scale factor of dilation, we don't need to add or subtract anything
Multiplying the x and y values of the ordered pair by 0.25 represents what the value would be with the scale factor, meaning multiplication.
Let x = width x + 30 = length 2x + 2(x+30) = 340 4x + 60 = 340 4x = 280 x = 70 Width x = 70 yd
Length x + 30= 100 yd
Perimeter = 2l + 2w= 2l=200 w=140 200+140 = 340 yd
The cost is what the manufacturer spends to make something
First differences are ... 0-7 = -7, -1-0 = -1, 4-(-1) = 5, 15-4 = 11, 32-15 = 17.
Second differences are -1-(-7) = 6, 5-(-1) = 6, 11-5 = 6, 17-11 = 6.
The second differences are constant at 6, so the table values would be best fit by a function that is ...
_____
The degree of the polynomial function corresponds to the level of differences that are constant (when the x-values are evenly spaced).
The quadratic function that matches these values is
... y = 3x² +2x -1
... y = (3x-1)(x+1) . . . . in factored form
I know that one other form is
800,000+1,000+6
