Algebra basically consists of mathematical operations, but using letters. To solve the exercises you only have to say that is the variable X

for Example: 4x= 8
                       x= 8 divide by 4
                       x= 2

In particular to the equations above, your goal is to find the value of x.

Step 1: isolate the variable (in this case,x).
Isolating the variable makes you narrow down what you are solving for.

Step 2: solve for the variable.
You can solve for the variable by making x alone (meaning with no coefficient).

If you have any questions on how you can do these while it still being mathematically legal, let me know and I will help.

What is the image of (-1, 1) after a dilation of 2?<br> (1,3)<br> (-2, 2)<br> (2, 2)
Amanda [17]
The answer is b. (-2,2)

Since it is a dilation of 2, multiply each number by 2.

-1*2=-2
1*2=2

So after the dilation, it would be (-2,2)

A sequence can be generated by using fn = 2f(n-1)+1, where f1 = 4 and n is a whole number greater than 1. What are the first fou
hoa [83]

Answer:

<em>{9,19,39,79}</em>

Step-by-step explanation:

<u>Recursive Sequences</u>

The recursive sequence can be identified because each term is given as a function of one or more of the previous terms. Being n an integer greater than 1, then:

f(n) = 2f(n-1)+1

f(1) = 4

To find the first four terms of the sequence, we set n to the values {2,3,4,5}

  • For n=2

f(2) = 2f(1)+1

Since f(1)=4:

f(2) = 2*4+1

f(2) = 9

  • For n=3

f(3) = 2f(2)+1

Since f(2)=9:

f(3) = 2*9+1

f(3) = 19

  • For n=4

f(4) = 2f(3)+1

Since f(3)=19:

f(4) = 2*19+1

f(4) = 39

  • For n=5

f(5) = 2f(4)+1

Since f(4)=39:

f(5) = 2*39+1

f(5) = 79
