Answer:

Last year Dr. Potter give<u> 32 </u>Polio vaccination and <u>28</u> measles vaccination.

Step-by-step explanation:

Given:

Each Polio vaccination consists of 4 doses , and each measles vaccination consists of 2 doses.

Last year ,Dr. Potter gave a total of 60 vaccinations that consisted of a total of 184 doses.

Now, to find the number of polio vaccinations and many measles vaccination.

Let the number of Polio vaccination be x.

And let the number of measles vaccination be y.

So, the total number of vaccinations:

x+y=60

y=60-x .......(1)

<em>As, given each Polio vaccination consists of 4 doses , and each measles vaccination consists of 2 doses.</em>

Thus, the total number of doses:

4x+2y=184

Substituting the value of y from equation (1):

4x+2(60-x)=184

4x+120-2x=184

2x+120=184

<em>Subtracting both sides by 120 we get:</em>

2x=64

<em>Dividing both sides by 2 we get:</em>

x=32.

<em>The number of Polio vaccination = 32.</em>

Now, putting the value of x in equation (1):

y=60-x

y=60-32

y=28.

<em>The number of measles vaccination = 28.</em>

Therefore, last year Dr. Potter give 32 Polio vaccination and 28 measles vaccination.

A line is perpendicular to y = - x - 2 and intersects the point (-5, 10)
Lady_Fox [76]

Answer:

y = x + 15

Step-by-step explanation:

If two lines are perpendicular to each other, they have opposite slopes.

The first line is y = - x - 2. Its slope is -1. A line perpendicular to this will have a slope of 1.

Plug this value (1) into your standard point-slope equation of y = mx + b.

y = 1x + b or y = x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (-5, 10). Plug in the x and y values into the x and y of the standard equation.

10 = (-5) + b

Simplify.

10 = -5 + b

Now, add 5 to both sides to isolate b.

15 = b

Plug this into your standard equation.

y = x + 15

This equation is perpendicular to your given equation (y = -x - 2) and contains point (-5, 10)

Hope this helps!

What does initial value mean?<br><br> (The topic matter is linear functions)
vagabundo [1.1K]
Initial value can mean many things, but what I believe it means in this area is the value that you start with (obviously), so in the equation (y=mx+b), the initial value is the b. It is where the line intercepts the y-axis, and that is your initial value, I believe!
I hope this was helpful and answered your inquiry! If you have any further doubts or questions, please let me know so that I can help you!

What is 96-8c=20-12
galben [10]

Answer:

c = 11

Step-by-step explanation:

96 - 8c = 20 - 12 , that is

96 - 8c = 8 ( subtract 96 from both sides )

- 8c = - 88 ( divide both sides by - 8 )

c = 11
