The vertex form equation is y = a(x-h)^2+k
Lets substitute our given information.

y = a(x-1)^2+5

Now, lets put in the coordinate it needs to pass through.

8 = a(2-1)^2 + 5
8 = a + 5
a = 3

Now, lets make the equation now that we know a.

y = 3(x-1)^2+5

Hope this helps!

The computation shows that the average monthly amount is 61.64.

<h3>How to calculate the value?</h3>

The amount that's left will be:

= 3314.85 + (2 × 926.65) - (1800 × 2) - 1075

= 3314.85 + 1853.3 - 3600 - 1075

= 493.15

The average monthly amount will be:

= 493.15/8

= $61.64

I really need help <br> it’s very hard

Answer:

The angle ZLK has a value of 75 degrees.

Step-by-step explanation:

We can calculate this as:

m\angle MLZ+m\angle ZLK=m\angle MLK\\\\(x+66)+(x+86)=130\\\\2x+152=130\\\\2x=130-152\\\\x=-22/2=-11\\\\\\m\angle ZLK=x+86=-11+86=75

We replace the angles values in the equation, as both angles that are formed with Z (MLZ and ZLK), when added, gives as the angle MLK. This allows us to calculate x. The value for x is -11.

Then, with the value for x we can calculate any of both angles.

The cost (c) to hire a dog trainer is varies directly with the amount of time (h) in hours spent training the dog.
NNADVOKAT [17]

Answer:

Part A) The proportional equation is c=55h

Part B) 8 hours of training

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Let

c -----> the cost to hire a dog

h ----> the amount of time in hours

The linear equation is equal to

c=kh

Sue spent $660 on 12 hours of obedience training for her dog Muffin

Find the value of k (constant of proportionality)

k=y/x

substitute the values

k=660/12=55

therefore

The linear equation is

c=55h

For c=\$440

Find the value of h

substitute in the equation and solve for h

440=55h

h=440/55=8\ hours
