Answer:

48/37

Step-by-step explanation:

Use the formula (y1 - y2)/(x1 - x2).

Plug in your x and y values to get (92 + 4)/(81 - 7).

Simplify down to get 96/74 and simplify again to get 48/37.

L varies directly with the square of Z. L is 12 when Z is 2. Find the value of L when Z is 4.
kow [346]

Answer:

L = 48

Step-by-step explanation:

Given that L varies directly with Z² , then the equation relating them is

L = kZ² ← k is the constant of variation

To find k use the condition L = 12 when Z = 2 , then

12 = k × 2² = 4k ( divide both sides by 4 )

3 = k

L = 3Z² ← equation of variation

When Z = 4 , then

L = 3 × 4² = 3 × 16 = 48

You have $2 and earn $0.50 for each cup of lemonade you sell. Write an equation in two variables that represents the total amoun
Pani-rosa [81]
So because you will have $2 no matter how many cups you sell the equation starts off as AA = 2 

Next, you add the dependent variable, because 1 cup of cc = $0.50 you add 0.5cc to the equation (it can also be written as 1/2cc), to complete the equation.
AA = 1/2cc +2

The glee club is having their annual Spring performance. The equation 5a+2s=48 represents the money collected on the first night
V125BC [204]
First, put them directly above each other.
5a+2s=48
3a+2s=32

You need to combine these, but in order to do so, we want to get rid of one of the letters. The S's line up very well, and all we need to do is multiply the bottom equation by a negative 1. This will look like this,
-3a-2s=-32                        (and add it to the other equation)
5a+2s=48
                         This gives you
2a=16
Divide both sides by 2 to get a by itself.

a=8, is your answer!

If it asked for s, you would put 8 into whichever equation seems easier for you, and then its just simple crunching it out.

Hope this helped!
