I need help with prob #2 on this
Aleks [24]

Answer:

<em>x and y are not in direct variation.</em>

Step-by-step explanation:

<u>Direct Variation</u>

Two variables x and y have a direct proportion or variation if:

y = k.x

Where k is the factor of proportionality. The value of k must be constant for every ordered pair (x,y). If only one of them does not have the very same k, then the relationship is not direct.

The value of k can be solved from the equation:

\displastyle k=\frac{y}{x}

Let's substitute the given points in the table:

<em>(2,8)</em>

\displastyle k=\frac{8}{2}=4

k = 4

<em>(4,16)</em>

\displastyle k=\frac{16}{4}=4

k = 4

<em>(6,30)</em>

\displastyle k=\frac{30}{6}=5

k = 5

Since the value of k is not constant, then x and y are not in direct variation.

Each polio vaccination consists of 4 doses, and each measles vaccination consists of 2 doses. Last year, Dr. Potter gave a total
Phoenix [80]

I think there is a little error in your question. I guess You mean 60 vaccinations instead of 606060. I solved using 60 vaccinations.

Answer:Dr. Potter gave 32 polio vaccines and 28 measles vaccinations that year.

Step-by-step explanation:

STEP 1

Let number of polio vaccines be x

and number of measles vaccine be y

such that

total does of 60 vaccinations be expressed as

x+y = 60---- equation 1

And number of doses for both  vaccine to total 184 doses taken be expressed as

4x + 2y= 184 ---- equation 2

Step 2--- solving

x+y = 60---- equation 1

4x + 2y= 184 ---- equation 2

Making x the subject of formula in equation 1 and substituting it in equation 2

x= 60-y

4(60-y) +2y- 184

240-4y+2y=184

240-184= 4y-3y

56= 2y

y= 58/2 = 28

To get x , put the value of y=28 in equation 1 and solve

x+y=60

x=60-28

x=32

Therefore Dr. Potter gave 32 polio vaccines and 28 measles vaccinations that year.
