Answer:
Dr. Potter provides vaccinations against polio and measles.
Each polio vaccination consists of 444 doses, and each measles vaccination consists of 222 doses. Last year, Dr. Potter gave a total of 606060 vaccinations that consisted of a total of 184184184 doses.
How many polio vaccinations and how many measles vaccinations did Dr. Potter give last year?
Step-by-step explanation:
Answer:
The scale factor is 2/3.
Step-by-step explanation:
Given data,
The given image is (6,9)
The image after dilation is (4,6)
The scale factor is calculated by dividing the resultant image by the initial image.
For example, if the initial dimensions are (x1, y1) and the final dimensions are (x2,y2). The scale factor is calculated using x2/x1 = y2/y1 = Scale Factor
In our scenario,
x1 = 6
x2 = 4
y1 = 9
y2 = 6
Scale Factor = x2/x1
=> 4/6
=> 2/3
Similarly for y axis,
Scale Factor = y2/y1
=> 6/9
=> 2/3
Therefore, the scale factor is 2/3.
If you meant...
(x^2+2x-5)/(6x-2)-(3x-2)/2
You need a common denominator of 2(6x-2)=(12x-4)
(2x^2+4x-10-(3x-2)(6x-2))/(12x-4)
(2x^2+4x-10-18x+6x+12x-4)/(12x-4)
(2x^2-8x-14)/(12x-4)
(x^2-4x-7)/(6x-2)
The value of A is 6 and B is 8
I think this is how it’s done.
