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? dr. potter gave polio vaccinations and measles vaccinations.

x - number of polio vaccinations

y - number of measles vaccinations:

x + y = 60    / * ( - 2 )

4 x + 2 y = 184

- 2 x - 2 y = - 120

+

4 x + 2 y = 184

2 x = 64

x = 64 : 2

x = 32

32 + y = 60

y = 60 - 32

y = 28

There were 32 polio and 28 measles vaccinations.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

y=mx+b

step-by-step explanation:

m slope, b y-intercept
