The ordered pair (0,0)(1,4)(2,16)(3,36)(4,64). write a rule that represents the function.
gayaneshka [121]
Let x represent first number in pair and y represent second number. We can see that x numbers are increasing by 1 on each next pair. y numbers are square of 0,2,4,6 and 8

Knowing all of that let "n" represent the position of the pair starting from 0!

than we can write that the rule is:
(n,(2n)^2)

Karen invested $2,000 in a special savings account.
WARRIOR [948]

Answer:

D. $512,000

Step-by-step explanation:

Well if the balance doubles every 5 years, then dividing 40 by 5 gives us the number of times the money will double, which is 8. We can then turn this into the equation 2000(2^{8}). 2^8 can be simplified to 256. Multiply that by 2000 and we get our answer, 512000. Hope this helps!

What is the solution to the system of equations graphed below?
Soloha48 [4]
Short Answer B
Remark

You need not do any calculations to get the answer. You are required just to read the graph. Doing the calculations would be beneficial but unnecessary.

Step One
Find the x value.
1. If you have a ruler or a straight edge of some kind, put it on the cross point of the two graphs.
2. Make the ruler go straight up and down. You will find out it goes 1 point back of the 5.
3. Count the number of squares from 0,0 or when y = 0.
4. You will find you have to count 4 squares along the x axis. 

The x value is 4.

Step Two
1. Put the ruler on the cross point again. This time make it go straight across. 
2. Count up from (0,0)
You should get 8.

The y value is 8

Answer: (4,8)
